Herbicide Cause Toxic Lake Algae

One thing about going to lake management conferences is that even though the issues remain the same, the people do not. Which means that ever year a few more homeowners or lake associations are getting educated about the things that matter for our lakes and ponds.

These meetings have given me the answer, the problem with our lakes are not the Weeds or the Algae blooms the problem is the people people who live on or near the lakes.

In Honor of Earth Day Lets Discuss Why Watershed Management is Important

by Paul Grosjean

Posted on 22-04-2016


Watershed management Strategies

With Earth Day approaching, it is prudent that we discuss watershed management as all the water that we and everything else on Earth needs to survive is funneled in some way or another through a watershed. What goes on it that watershed can affect the water quality and thus the health of every living thing that is dependent upon it. Consequently, it is vital that we take steps to protect our freshwater systems by implementing adequate watershed management strategies.

Don't be a Fool When it Comes to Lake Weed Control

Lake Weed Control April Fools

If you are fortunate enough to own a lakeside property, you may also have the misfortune of having to deal with encroaching lake weeds which will necessitate some form of lake weed control if you wish to utilize the watery domain on your doorstep. Aquatic weeds tend to proliferate when there is an abundance of nutrients flowing into the lake. This is particularly problematic when your lake is situated in close proximity to a built-up (urban or residential) area with lots of impervious concrete surfaces which promote runoff of pollutants such as fertilizers via stormwater runoff. Fertilizers are one source of nutrient enrichment; others include sewage leakage from septic tanks and manure from livestock. These pollutants can also come from non-point sources further upstream, making it extremely difficult to pinpoint or control the direct source.

Weed Blankets

Is it too late in the season to install your LBB "weed blankets"? This is a question I get all the time. The Beauty of our "Weed Blankets" is that they can be installed anytime of year. For instance, I have a customer that install there LBB's the first week in August when they go to their lake home. I have another that uses them at a lake rental home 3 separate weekends, they install 2 blankets Friday and pull them out on Sunday each weekend they go. Instant swimming area for the kids.

Kill Lake weeds - Lake Cochituate, MA Herbicides use?

by Paul Grosjean

Kill Lake weeds

Lake Cochituate, MA fighting an uphill battle trying to kill pond weeds? In Massachusetts there is a lake that sit right behind the Natick Mall, it's easily seen off Route 90 and was used as a reservoir for Boston years ago. Lake Cochituate is a beautiful lake in the suburbs of Boston, but over the last decade or so things have changed.

View of hard surfaces around lake

Take a look of this lake from the sky, there is more Grey areas then green - indicating huge amounts of impervious ground. The Natick mall and all the development to the east and south has added to huge run off issues. The watershed is currently stressed by nonpoint source pollution, primarily urban stormwater runoff from impervious surfaces, decreased groundwater recharge, growing invasive lake weeds infestation, and shoreline erosion from steep slopes, shoreline development, recreational use, and highway crossings. Give this lake no ability to fix itself. Now after years of discussion the State is allowing the use of approved herbicides for Lake Cochituate to learn how to kill pond weeds the ones that are choking the shallower areas of the lake. The homeowners are worried about the water supply, and what effect the chemical will have on it. They should be worried, but not for just the chemical but for the long term effects on the water. Herbicides are used in lakes all over the world, but studies are showing that it doesn't solve the problem, and in many cases make a much bigger problem. Algae (Please see earlier posts that describe why chemicals are not the answer to killing pond weeds). Killing pond weeds isn't the main issue at Lake Cochituate, pond weeds are just a byproduct of the root problem, which is bad watershed management due to overdevelopment. To fix the watershed in that area may not be possible, I think this is a recurring topic that will see the demise of many bodies of water over the next 25 years if not taken seriously.

What is Watershed Management?

by Paul Grosjean

Posted on 06-06-2014


Watershed Management | Lake Bottom Blanket

I throw out the phrase "Watershed Management" a lot, but what does it mean. Well in a nutshell it means the area of land that captures the rain that eventually flows to the lower lying lake, stream or even ocean. Most of our lakes get a high percentage of its water from "Runoff" from rain events. So when you look at a 1000 acre lake it can have several thousand acres of watershed feeding the lake. A watershed can be made up of forests and vast undeveloped land. In areas that are more developed it encompasses everything, roads, houses, farms, toxic waste dumps, etc. and what it ultimately is, is a funnel to the lake or body of water that is below it.

Rogers Lake Old Lyme CT

Invasive Lake Weeds | Lake Bottom Blanket

CT lakes have weed issues, like most states in the northeast, but they also have a DEP that is willing to help the property owners. Our lakes are more than just recreational area in the summer, they are habitats for animals and a source of water for many communities. The cost to own a home near a lake is much greater than homes that are not associated with a lake. So, property values are tied to the lakes and if a lake is not well maintained, IE. not usable for recreation, then the values drop. This makes homeowners very upset...so they contact a company that sells the "Pill to fix" your problems. Aquatic weed control and water quality are a difficult balance, on one hand you want uninhibited use of the water, but in the other hand you also want crystal clear water. Why can't you have both? You can if you're willing to change how you think about your lake.

Lake Weed Control

Lake Weed Control | Lake Bottom Blanket

The prevailing thought is that the late spring might reduce the amount of lake weeds or even stunt the growth of algae in our lakes and ponds. Well, that is just not the case. I have talked with several customers that believe the issues have actually gotten worse. How can that be? "Ice on the water is sure to reduce the sunlight to the bottom, so lake weeds will not grow". But you're not understanding the ecology of the lake. One thought is that the lake bottom, water column, and run off is still full of nutrients, and these nutrients are looking to feed something. If the lake weeds in your lake are slow to grow due to lack of sunlight then you're left with the production of algae. Algae doesn't need as much light to grow. The shallow area are first to see increased algae production, and as the water itself becomes more opaque you begin to naturally retard lake weed growth. This cycle causes Algal Blooms.

Aquatic Herbicide | Lake Bottom Blanket

Over the last few months I have been shown several news articles that describe how locals are hesitant when it comes to using chemicals to provide weed control on the lakes they use as water supplies.

The fact is that most thinking people view the use of such aquatic herbicides as a problem that can adversely affect their lake and themselves. Another fact is we have been using aquatic herbicides for years and the question remains are the lakes better off now? Are we healthier now after consuming all this stuff?

Milfoil Problems in Maine?

Eurasian Milfoil Invasive lakes weeds in maine

I have seen several articles that discuss the issues that Maine is facing with this exotic weed Milfoil . It seems they have woken up to the fact that this problem is getting worse. They are worried about the Variable leaf variety that has been found in over 27 lake in Maine. What's even worse is the fact that Eurasian milfoil has infiltrated some lake systems too, and that's a real tough weed to control. Both these weeds are able to reproduce by fragmentation, so motor boats and any harvesting can have an adverse effect on the entire water body.

How to kill lake weeds

Why you should not use Chemicals to kill lake weeds, For the those of you that are fortunate enough to live on or near a lake you know the answer to that question. "eeeewh, I'm not swimming in those weeds" or "Every time I take my boat out I get this mass of lake weeds tangled in my prop" In the mind of a homeowner Lake weeds add very little value to their recreation. There is this idea that if we were to kill all the lake weeds we would have this beautiful clear area to swim, boat and fish....That idea would be very wrong because of many reasons, first being the wildlife that live on or off of the weeds that you want gone wouldn't survive.
