Mother Nature Takes a Toll in Our Lake Y Project with Bassmaster

May 24, 2023

By Lochow Ranch

Episode 9 of our video series with Bassmaster to turn Lake Y into a bass fishing paradise entered some choppy waters, indeed flood waters, and includes how they and other natural catastrophic occurrences can affect your pond or lake.

The Lake Y project aims to educate anglers and pond-owners on how to identify opportunities to improve small lakes, and steps to take to turn an average lake into bass fishing bliss.

So far the series has explored topography, water source, water quality and clarity, area predators such as otters, vegetation, fertilization, pellet feeding, and electrofishing to understand the state of the 56-acre creek-fed lake.

Bassmaster editor James Hall in this episode talked about what appeared to be a 10-year flood that affected the lake. The dock he stands on had been about a foot underwater, he said, and the spillway had 3-4 feet of water going over it.

John Jones, president of Lochow Ranch, said the flooding was bad enough that it created currents that could have swept forage fish downstream. Lake Y is on a large watershed, John has said previously, and he could see a change in its water quality.

Flooding can have a lot of impacts, John said. “The first is you’re flushing the lake with new water, maybe water you want, maybe water you don’t want.”

Flooding can bring undesirable quantities of nutrients, and cause things like harmful algae blooms. “A small flood generally speaking is not going to cause too many problems for fish,” he said. “Most game fish species swim upstream. The smaller fish, the blue gill and bass, when they’re tiny, generally will go with the current, but most of the fish go upstream.

“When you get big currents in the flood like you’re talking about, you can lose a lot of your bigger sport fish. It can be heartbreaking. Maybe good for your neighbor, but not good for you.”

Managing Mother Nature isn’t easy, he said. “I would say if you’re going to grow big fish, you want to have no catastrophes, no accidents, you want to do boring things for 10 years, but Mother Nature pretty much without fail will make sure that doesn’t happen.”

James noted that Lake Y has also suffered the opposite of flooding: 45-50 days of no water, no rain whatsoever. The water dropped to the lowest point he’s seen, “probably three feet lower than we’re seeing there right now,” he said.

John explained that in some ways drought can be beneficial. “A seasonal drought can concentrate the bait fish, pull them away from the structure, and expose them to predation. You can get some really fat bass,” he said.

But probably the biggest problem with a minor drought is it will cause weed growth and lead to a devastating fish kill, he added, especially in the summer.

James also mentioned natural predators, such as cormorants, pelicans and otters – all of which can have a big impact on fish numbers.

John said cormorants can mainly hit your bait fish and on average eat about two pounds of bait per bird per day, so put a retail value of 25 bucks a pound on your bait and that’s $50 a bird a day.

Pelicans, he said, also eat bait and medium-sized bass but are generally a problem in bigger lakes. “We don’t see them as often in smaller lakes. Of course, you know both birds are protected so there’s not a whole lot you can do about them,” he said. But lake owners can do non-lethal things to deter them from the area.

As for otters, John said they’re a sign of a healthy ecosystem, but they can also put a big hurt on your fish population. An otter will eat about 7 pounds of fish per day and can kill up to 28 pounds of fish per day, he said, which he’s seen destroy bass fisheries. Though otters are nocturnal, he said there are several signs that out them as culprits

“It’s important to understand what can happen so you can kind of prepare and take action and do things that might prevent some of these catastrophes from happening,” James said.

John answered, “Absolutely. You can stave off most of those. You can stave off a turnover by having an aeration system. You could stave off a blue-green algae kill by doing proper treatments. You can work on the predators. You’re never going to eliminate Mother Nature, but you can mitigate the impacts of those type of things.

“Floods, not so much. If you try to keep your fish in with fences and things, you could end up hurting your dam and you certainly don’t want to do that. A drought, you know you can pump supplemental water. So there are ways to mitigate every one of these, but generally you want to identify it as it’s happening and not wait till your point of no return and then try to fix it. That rarely works.”

Electrofishing in Action: Bassmaster’s Lake Y enters its Third Year

February 12, 2023

By Lochow Ranch

Our partnership with Bassmaster to turn Lake Y into a bass fishing paradise enters its third year in the latest episode.

Bassmaster editor James Hall says it’s about 12 months since a truck full of coppernose bluegill were added into the underperforming Alabama lake and since then, it has gone through some significant flooding.

John Jones, president of Lochow Ranch, leads Hall through some good, some medium, and some bad (but recoverable) news. The flooding was bad enough that it created currents that could have swept the bluegill forage fish downstream, he says.

But only an electrofishing survey would provide a clear snapshot of what was happening, he adds. The last such survey had been performed about a year prior.

The Lake Y project aims to educate anglers on how to identify opportunities to improve small lakes, and steps to take to turn an average lake into bass fishing bliss. So far in the series, John and James have explored topography, water source, water quality and clarity, area predators such as otters, vegetation, fertilization, pellet feeding, and electroshocking to understand the state of the 56-acre creek-fed lake.

Lake Y is on a large watershed, John says, and he could see a change in its water quality from the flooding, making it less desirable. “You can see the creek influences on the lake,” he says.

The electrofishing shows bait and bass numbers are up. As he measures and weighs the fish, Lochow Ranch Fisheries Biologist Brandon Booth says it’s important to keep predator and forage numbers at proper levels so bass growth isn’t stunted.

But many of the fish have red sores, which John explains is common with flooding.

It’s “something we see a lot of especially in the spring or the fall, during years we’ve had a big influx of water,” he says. “We’ll see bacteria counts, they’ll get a little bit higher, and you may have fish that get a little bit stressed and they’re susceptible to getting infections.”

The fish will recover, he adds.

“So that’s good news. So if you all see fish like this, they have the crazy sores on your lakes, know that all is not lost. Thankfully these fish are going to survive,” James says.

The survey also reveals less desirable fish for Lake Y, such as sucker fish and channel catfish. Because the lake is shallow, they will stir up the silt, making spawning harder and managing the pond a lot tougher.

So, good news on the bass; great news on the bait, John says. “That’s the foundation. If you want fat cows, you need lots of green grass.”

The previously added structure piles “worked like a charm and so we got big fish.” More structure piles would be beneficial, he said, but because Lake Y is shallow, some owners might not like to be able to see them.

The medium news, he says, “You still have lots of nongame species there. I think that’s life on the creek.”

As for the biggest challenge moving forward: “That’s pretty straightforward, it’s gonna be the actual construction of the lake. So this lake is a shallow lake. If we improve the water quality we’re gonna grow a lot of weeds, which is gonna be undesirable for some of the people out here,” John says.

“Just getting around how this lake was constructed to begin with is our biggest single challenge,” John says. “We’re already making progress on the bait. We’re making progress on the bass. We’re going to make progress on the genetics. But we are still dealt the hand that we’re dealt here.”

“I’m excited about the progress for Lake Y,” James adds.

Focus on Feeding: Where do you get the most bang for the buck?

June 30, 2022

By Lochow Ranch

Fish feeders are a common sight at many private lakes and ponds. But if your goal is to grow trophy bass, is your feeding strategy tuned to maximize growth?

That was one of the points our president, John Jones, made in his recent interview with Bassmaster Radio.

Host Thom Abraham asked John about his advice for feeding options for pond and lake owners who are looking to maximize growth of gamefish and panfish.

“First off, of course, in the well-balanced pond or lake, you do not need to stock fish repetitively,” John said.

“There’s an amount of growth that a body of water can sustain that’s based on water quality inputs, fertilizer, generally the health of the water, because that’s the base of the food chain,” he said.

In the interview, Thom and John discussed a range of lake management and fishery management tips, stemming from our work with Bassmaster on the Lake Y Project. They explored a topic that many people ask about, supplemental feeding and other steps to spur fish growth.

John explained that supplemental feeding is sometimes accompanied by pond or lake fertilization, which can nourish the whole lake food chain. “If you want to supplement what that natural process will grow – and a lot of times in a private lake, that’s somewhere between 40 and 300 pounds of total fish per acre – you can move to fertilization, which can raise the total poundage of fish 500 or maybe even 1,000 pounds per acre. But really, probably 500 would be a max with a really heavy fertilization program.”

He continued, “But a safer way to do that is to use a pelleted fish food. Pelleted fish food is how commercial farms grow fish. It’s the cheapest way to grow fish safely.

“And generally speaking, depending on the quality of the feed, if you use a good quality feed you’re going to grow about a pound of bait fish for every 2 pounds of feed.”

John said a lot of people feed their fish but use low-quality feed that is less expensive. It’s a case of you get what you pay for, and he recommended buying the best quality feed you can afford.

“And just know that if you buy the highest quality feed, for every 50-pound bag of fish food you put in, you grew 25 pounds of bait. You can skip that step and move directly to stocking bait. But buying bait, you’re cheating time and it costs a lot more money.”

John concluded, “It roughly takes about 10 pounds of bait to grow 1 pound of bass. So you could see, it could add up pretty quickly. I recommend people to stick with a good pelleted feeding program if they want to supplement the natural processes.”

Along with supplying fish feeders and feed, Lochow Ranch can provide feeding guidance to maximize the productivity of your fishery.

We teamed with Bassmaster to take an anonymous 56-acre lake in Alabama and turn it into a thriving bass fishery.

Our project with Bassmaster: ‘Let’s get shocking’

April 25, 2022

By Lochow Ranch

“It’s all about the process,” writes Bassmaster editor James Hall, referring to a favorite principle of Alabama’s football coach in the latest write-up about our Lake Y project.

And each step of the fishery management process is important for turning Lake Y into a bass fishing paradise.

That’s how we found ourselves in Alabama last fall conducting the second electrofishing survey of Lake Y.

We have teamed with Bassmaster for The Lake Y Project, as we look to turn an underperforming 56-acre lake in Alabama into a thriving fishery.

Now in year 2 of the project, we are running through the steps of the process for effective fishery management, including understanding the lake’s current conditions, creating a plan to improve it, and then executing on that plan.

“Let’s get shocking,” said John Johns, president of Lochow Ranch, as he kicked off the second electrofishing survey of the lake in Episode 6 of the video series Bassmaster is publishing about the project.

The first electrofishing survey of Lake Y last spring showed there were a number of undesirable fish species in the lake, John explained to James. The next step in the management plan and process is to conduct a second survey and take action to remove some of those fish.

The nature of Lake Y, with its water inflows and outflows, means these undesirable species will not be able to be eliminated entirely, John said, but at least they can be managed. That will give bass and forage fish the chance to thrive.

Electrofishing in action

If you have ever wondered about electrofishing and how it works, the latest Lake Y video provides a great overview of the technique.

Electrofishing is considered by fishery biologists to be the best approach to inventorying the fish population of a lake.

An electric current pushed into the water by a specially-designed boat briefly stuns the fish. The fish are collected and weighed and measured for recording by our fishery biologists, then returned unharmed to the water.

“We get to see the fish, how they’re doing, weigh them, measure them, check on their body condition, really get a sense of how and where a lake is in its development process,” explained Matt Ward, one of our fisheries biologists, in the video.

Matt showed multiple examples of undesirable species of fish that the second survey found in Lake Y. These fish can end up competing with the fish you do want in the lake, such as bass and the forage fish that they feed on.

Often these fish can be removed during an electrofishing survey. Or, as in the case of Lake Y, trotlines can also be run to catch and collect the undesirable species to remove them from the lake.

Lake Y project proceeds: pond stocking & feed

In addition to the population surveys, we conducted pond stocking at Lake Y, introducing coppernose bluegill to provide forage for bass and boost growth.

Another step was to add supplemental food for the fish. Installing our fish feeders and providing high-quality food is an important factor to further spur growth of bass.

We’re also booking electrofishing surveys for the season, as well as taking orders for pond stocking. Get in touch to schedule yours today!

Spring has Sprung: Pond Management Tips to Prep for an Epic Fishing Season

April 8, 2022

By Lochow Ranch

Now is the time of year that pond management activity starts kicking into high gear as we prep for a great fishing season.

If you are looking forward to catching some trophies in your water body this year, good fishery management needs to include surveying your fish population, and stocking your fish supply, as well as taking stock of their vegetation environment and deciding on your strategy for controlling pond weeds.

Smart managers recognize these as three of the most important spring tasks to ensure 2022 will be an angler’s dream.

Fish Surveys: Electrofishing

Knowing what lurks in your lake is key first step to planning pond stocking.

The best approach for inventorying your fish population is an electrofishing survey. This key action is perfect for both diagnosing problems in established lakes as well as a routine management tool to identify issues before they become expensive problems.

Electrofishing is an excellent tool for correcting an out-of-balance water body by assessing the numbers of forage and sport fish. Electrofishing also allows for assessing winter cormorant or otter damage, as well as providing a snapshot of species’ size, relative abundance and growth rates.

Through electrofishing, experts can also ID unwanted species and quickly remove them before they become a problem.

This standard scientific survey method causes no long-term negative effect for the fish. The fish are briefly stunned, examined and quickly returned to the water unharmed.

The survey result becomes a reference point for a long-term fishery management plan. A manager will use it to plan for corrective stocking and harvest recommendations.

Our fish experts can conduct an electrofishing survey for you using state-of-the-art techniques and equipment. Click here to learn more.

Pond Stocking: Key Considerations

Stocking of both game fish and forage fish can maximize the productivity of your fishery.

After a survey of your fish population, you can use pond stocking to reconcile winter losses and establish a proper predator-to-prey ratio.

But fish stocking itself takes some planning and awareness of the factors particular to your lake or pond. You need to know what kinds of fish will thrive in your body of water. You also need to assess the impact of using non-native species as well as the types of fish that can live together and sustain a healthy ecosystem.

Professional pond stocking advice is key because pond management must be handled with skill and exactness. Indeed, small and large ponds and lakes must be stocked and managed differently. And location, fish health and condition must be considered, as well as understanding spawning and other characteristics of the specific fish you want.

Our fish stocking professionals can help you navigate the considerations for pond stocking to arrive at the best plan for your lake or pond. Whether you are selecting specific fish for stocking or need advice on which fish to stock in your pond or lake, our team can help.

Fish stocking options often include largemouth bass Florida strain, largemouth bass native strain, trout, crawfish (or crayfish), and many types of forage fish. We are the pond stocking partners trusted by landowners across Texas, Arkansas, Oklahoma and Louisiana.

Pond Weeds: Get Ahead of the Growth

Getting an early start on controlling pond weeds is the right strategy to keep growth in check this year.

Now in the early part of the growing season is the time to take action. Pond weeds can dominate shorelines putting a hitch in fishing or swimming. Some vegetation is beneficial for fish and other organisms.

But out of control growth of pond weeds also can negatively impact aquatic organisms through a process called cultural eutrophication.

Your water body is a small ecosystem cut off from many of the elements that maintain balance in natural waters. This means active control of pond weeds is a must and you should plan for continuing such steps throughout the growing season for your pond or lake to be its best.

Treatments options include an array of products, equipment, herbicides, lake dyes and algaecides to help rid your property of nuisance aquatic plants or issues with floating, submerged or emergent pond weeds. There also is a chemical-free approach that can include stocking triploid grass carp and tilapia, which are among the most popular biological alternatives for removal of pond weeds.

You may also want to consider nutrient precipitation, pond liming and fertilizing regimes, and aeration systems to promote plankton blooms that improve the health of your pond, keep things in balance, and mitigate issues with excessive pond weeds.

Our experts can help you assess the right approach to controlling pond weeds in your body of water.

Our project with Bassmaster: Lake structures can improve an underperforming fishery

November 24, 2021

By Lochow Ranch

Our project with Bassmaster reached a very important milestone in the latest installment of the video series: the addition of structure to Lake Y.

Structure refers to the underwater features that give bait fish and young bass shelter and larger bass a place to feed.

For Lake Y, adding structure to make a fish friendly habitat will be one of the most important steps in creating a prime bass fishery, according to Lochow Ranch President John Jones.

We have teamed with Bassmaster for The Lake Y Project, focusing on turning an underperforming 56-acre lake in Alabama into a thriving fishery.

In Episode 4, John and James Hall, editor-in-chief of Bassmaster Magazine, dive into the importance and types of structures that can be added to lakes as part of fishery management.

The video installment can be viewed here on the Bassmaster website. The video features explanations of structure options and then follows members of the Lochow Ranch pond management crew as they add several structures to Lake Y.

“What we like to see in a lake is somewhere around 20 percent structure,” John explains. That much underwater structure helps the bait and game fish population to grow while still affording good fishing.

John and James survey the different types of structure that are commonly used.

A popular form of lake structure is old Christmas trees. A tree can be weighted at the base with cinderblocks so that it can float upright and fish can shelter among the branches.

The positives of Christmas trees are that they are an inexpensive approach and can be easy to find if you ask neighbors to let you take their trees after the holiday season.

But there are several drawbacks, John says. Christmas trees disintegrate in a few months in a lake and no longer offer adequate structure. They also can snag lures, and getting a hook unsnarled from an underwater Christmas tree is very hard.

That said, Christmas tree can work very well as fish-friendly cover while they last, John says. One pond survey the Lochow team conducted found 150 bass at a single Christmas tree.

Another structure option is to sink bundles of brush including pieces of hardwood. This can be much longer lasting than Christmas trees, John says, explaining that he has seen hardwood structure that was still effective 15 years after it was placed.

When putting in brush as structure, John says, it is best to use bundles and to place the bundles in roughly the size and shape of a semi trailer.

You want brush structure placement to be long but narrow so that the fish have cover but also so that you can get access to where the fish are for good fishing.

The final type of habitat elements that John and James discuss is the manmade structure. Naturally these are very long-lasting and provide excellent cover for fish. They don’t create as many headaches with snagging lures as sunken trees do, and it is relatively easier to extract a caught hook from an artificial structure.

For Lake Y in particular, the addition of structure is key to improving the lake’s performance as a fishery.

In fact, fish were spotted around the Christmas trees shortly after they were installed in Lake Y. “To say that this lake was dying for some structure, these fish were needing some structure, may have been an understatement,” James says.

Adding structure to an underperforming pond is a very important step in fishery management, John says, but you need to make sure you have your goals in mind and realize it can take time and patience for a fishery to reach its prime.

“You want to put forth your goals and you want to make them attainable,” John advises. “So it’s not reasonable to assume we can get everything done overnight. Taking something like a lake with almost no structure and getting it to 10 to 20 percent is going to take several years.

“But once you’ve got a good plan, and you’re efficient and you stay targeted with what you’re doing, you’re going to get there.”

John started his assessment of Lake Y in the first episode with a walkabout, identifying overall problems and opportunities. The second episode focused on inventorying the lake’s existing fish population, highlighting an electrofishing survey in action. The third episode explored water quality, clarity and vegetation management considerations.

Our project with Bassmaster: Clues about clarity, pointers about plants

September 20, 2021

By Lochow Ranch

The third installment of our video venture “The Lake Y Project” with Bassmaster is short but important and focuses on water clarity and vegetation management.

Lochow Ranch president John Jones is quick to tell James Hall, editor-in-chief of Bassmaster Magazine, that all water’s not created equal as the two continue their conversation about how to transform an average lake into a fishing paradise. You can see Episode 3 here.

“We try to use water clarity to our advantage,” John says. “The perfect bass lake would have somewhere around 18 to 24 inches of visibility. The water would be a dark green color, nothing floating on top of the water. That would produce a lot of phytoplankton, grow a lot of baby fish and, importantly, shade out submerged weeds after a certain depth. We like to reduce light penetration.”

Lake Y, an anonymous 56-acre creek-fed lake in Alabama, has suboptimal water clarity, John says. “Certainly, it’s not horrible,” he explains. “We’ve had many, many lakes with 1 inch or less of visibility. Those lakes are generally very unproductive.”

For really “choked” lakes, you’ll find three main categories of pond weeds, he says: emergent plants such as cattails; submerged plants such as hydrilla; and floating plants such as the white water lily.

When designing a new lake, John likes to plan for 20-30 percent vegetation coverage. “That’s not always possible,” he says.

As he examined Lake Y, John says, “This is a very common plant community for a lake that’s got probably, honestly too many grass carp in it.”

Adding grass carp are an inexpensive route that lake owners often take to reduce submerged pond weeds, he says. “I like to say using grass carp to control your lake is like using goats to mow your yard,” he says. There are pros and cons.

Used correctly, they’re an affordable way to reduce submerged pond weeds at a tiny fraction of the cost of herbicides, and are a great tool with proper fencing and management. But unmanaged they will almost always cause a crash in your bait fish and bass conditions in the longer term.

John identified mainly woody, dense-type species of pond weeds that grass carp don’t like such as water willow and milfoil. He also pointed out emergent cattails in the dam area that could attract beaver dens and secretly damage the dam.

John says he’d add a couple of plant species that are easy to fish, not too invasive, would thrive and be easy and inexpensive to treat, as well as being preferred by grass carp. He says using EPA-approved herbicides or algaecides around the dock areas – which are almost always too dense – is optimal for anglers of all skill levels.

As lake owners keep a close eye on weeds, they also need to be aware of harmful or invasive species, he adds. States are already responding to problems that private owners aren’t seeing yet, but most likely will.

John started his assessment of Lake Y in the first episode with a walkabout, identifying overall problems and opportunities, then followed in the second episode with an electrofishing survey to reveal the lake’s fish population.

Our project with Bassmaster: Electrofishing in action

August 31, 2021

By Lochow Ranch

In episode 2 of our Bassmaster project, we find out what lurks in the depths of “Lake Y.”

You can see an electrofishing survey in action as we categorize the fish population of the anonymous 56-acre creek-fed lake in Alabama.

Click here to check out episode 2 of our video series with Bassmaster, “The Lake Y Project.”

Lochow Ranch president John Jones chats with James Hall, editor-in-chief of Bassmaster Magazine, to discuss the species, sizes and weights of fish found during the survey.

Electrofishing briefly shocks and paralyzes fish and allows for a lake management inventory of the population to be created.

John first studied Lake Y with a walkabout, identifying problems and opportunities. John advised Lake Y owners start an improvement strategy with satellite photos identifying other water body influences and an examination of the lake’s history: when it was built, watershed influences and management approaches. He identified Lake Y as being off color and in a shallow ravine with a small dam.

His visual assessment also included evidence of otters, and identified issues surrounding the lake’s number and condition of boats, fish feeders and spillway.

Bassmaster says Lake Y “could well represent the majority of small lakes and ponds scattered throughout the country.” And, indeed, that’s exactly what John found after analyzing the data his team collected during the electrofishing survey.

“Really, this is a very average lake,” John said, “which is a great starting point. This is what people are dealing with all over America. You’re overpopulated with small stunted bass, not horrifically so but certainly so. You have all the right species in the lake. In addition, you have some species that, we’ll call them undesirable, stuff that’s not really adding to production.

“I feel like we got great data today,” he added.

There are lots of variations of electrofishing boats, John explained, but Lochow Ranch “basically builds ours in-house.” A generator using between 10-50 amps pushes about 10,000 volts through cables attached to the boat. The current puts fish in a state of temporary paralysis and allows for easy collection and analysis.

One survey will produce a dataset of about 3-5% of the lake. Lochow’s teams use it daily both for exploring new populations as well as for managing existing populations. Multiple electrofishing surveys over time will allow for an even more complete picture.

It’s an excellent tool for correcting an out-of-balance pond. Stunted fish or unwanted species can be easily and quickly removed as part of the service. And the survey acts as the reference point for a long-term pond management plan and provides clues for corrective stocking and harvest recommendations.

While on the boat, Lee Schoech, one of our fisheries biologists, identified several species, including largemouth bass; freshwater drum (which indicated the creek is substantial); channel catfish; carp; threadfin shad and gizzard shad; bluegill; crappie; redear sunfish; longnose gar and spotted gar among them.

Lee rubbed swabs on the tongues of the fish to get their genetic profile and establish a baseline for the fishery.

Asked about his gut feeling on Lake Y, John says, “I’m going to enjoy this project. … I believe this lake is going to take just some very traditional improvements. It’s going to do a heavy feeding program, a quality stocking program. We’re going to look at the genetics on the fish.”

But in the next episode, Lochow and Bassmaster are going to focus on ways to add structures and cover to the lake and create much-needed habitats to increase productivity. The structures also create areas where fishermen know they can find fish.

Capping off the episode, James asked John about some of the craziest things John has shocked up in his career of electrofishing surveys.

The largest largemouth bass he’s personally shocked was 19.1 pounds, John replied, as well as a lot of fish in the 15-16-pound category. He’s pulled alligator gar he believes were well over the state record; blue and yellow cats approaching triple digits; and goldfish over 10 pounds.

Aquarium fish such piranha are always a surprise, but the cormorants, alligators and the 60-70-pound beaver were also very memorable, he said laughing.

Avoiding Noxious Algae: What to do when blue-green algae shows up in your lake or pond

August 23, 2021

By Matt Ward

Cyanobacteria or blue-green algae is a large group of photosynthesizing organisms that are more closely related to bacteria than to green algae or pond weeds.

Technically this means that they are in a category of their own and have attributes that make them and their management unique.

This article will discuss cyanobacteria and their management, touching on major concerns and primary management techniques.

Blue-Green Algae Concerns

After the death of some dogs that drank water tainted with blue-green algae in Texas lakes in 2019, blue-green hysteria seemed to strike the country.

Concerned dog-owners quit allowing their dogs to enter our public waterways or drink from untreated surface water. The truth is that all surface waters contain some amount of blue-green algae and many of these algae are able to produce toxins that can be harmful or even fatal to living organisms that absorb those toxins.

Most intake is through drinking though theoretically enough toxin could be absorbed through the skin to cause harm. In short any water body could have blue-green algae toxin in them and cause harm to animals that use those waters.

That being said, problems are most common when blue-green algae growth is dense. This growth can produce turquoise or emerald green film or sludge, dark green matted algae, particulate plankton aggregates, or many other forms of singular or collective cellular growth.

This growth is typically accompanied by strong smells and is almost universally judged as unsightly. Dense cyanobacteria growth always has the potential to suddenly release cyanotoxins which in turn can produce acute and chronic health consequences for other living organisms including fish and mammals.

Ultimately if your water body has dense cyanobacteria growth, fish and mammals that utilize that water are potentially at risk. If you don’t have that dense obvious growth the risk is greater than zero, but certainly reduced.

Particularities of Blue-Green Algae

Blue-green algae has a handful of attributes that lake managers need to understand to better manage its growth.

First, blue-green algae loves phosphorus. In scientific terms, low N/P (nitrogen to phosphorus) ratios favor blue-green algae over vegetative and green algae growth. Practically speaking this means that when fertilizers containing phosphorus are applied to a watershed, or manure builds up in the same, phosphorus levels will peak along with blue-green algae growth.

Second, even in the absence of excess phosphorus, blue-green algae have adapted to their environment by developing a phosphorus-mining technique. To do this, filamentous blue-green algae will smother the substrate, causing the pH to drop along this interface which in turn releases phosphorus from the sediment where it is commonly found.

Regardless of how the phosphorus ends up in the water column, blue-green algae soaks it up and grows extremely rapidly in the absence of competition. This means that ponds that have a lack of beneficial growth will tend to grow more cyanobacteria than those that do.

Finally, blue-green algae grows perfectly well in extremely hot water and while other plants slow their growth in the middle of the summer. This leads blue-green algaes to experience peak growth in mid-summer.

Management Objectives

The first step in managing blue-green algae is to kill excessive growth when it shows up.

Treatments can be done with various copper formulations but may also be done with various peroxide based chemistries. Growth forms will dictate which product and what formulation is best but know that granular and liquid products are needed in different situations.

It is also important to note that sometimes when algae is treated it can actually release toxins into the water column as it dies. This is where peroxide-based chemistry is particularly useful as peroxides are able to actually neutralize some of the algal toxins.

Proactively speaking there are two main approaches to managing blue-green algae growth.

First, N/P ratios can be manipulated and, second, total phosphorus can be reduced.

Many articles have been written about manipulating the N/P ratios in a given fishery. But in our experience it is seldom that adding some nitrogen to a waterbody suddenly shifts blue-green algae growth to green algae or vascular vegetation. More commonly, reducing phosphorus is key to pushing the N/P ratio in a positive direction and reducing the amount of blue-green algae growth a lake experiences.

There are three methods for accomplishing this:

Take steps to limit phosphorus inputs by reducing livestock densities and reducing fertilizer applications in watersheds.
Remove phosphorous that does end up in a lake through mineral sequestration via applications of aluminum sulfate or lanthanum bentonite or through uptake by beneficial aquatic vegetation.
Limit phosphorus levels by aerating a lake to prevent anaerobic conditions on the sediment interface.

Vigilant Algae Control

Keep an eye out for blue-green algae and if you have it take steps to reduce the growth. Treat excessive growth, limit phosphorus inputs, and when growth is dense keep your livestock off the pond or lake. Management of blue-green algae growth is a key to pond management success and maintaining a healthy water body.
