Not only do chemicals kill off all weeds but it kills off all the fish as well and then about 5 weeks later the entire lake is overgrown with algae.

Kill Lake Weeds
Why you don’t use Chemicals to kill lake weeds
Why Kill Lake weeds in the first place:
For the those of you that are f ortunate 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 home owner Lake weeds add very little value to there recreation. There
is this idea that if we were to kill all the lake weeds we would have this beautif ul clear area to swim, boat and
f ish….
That idea would be very wrong because of many reasons, f irst being the wild lif e that live on or of f of the
weeds that you want gone wouldn’t survive. These plants provide shelter f or small f ish, and absorb nutrients
that is in constant abundance in the lake. So, killing all the lake weeds would be a bad idea.
Herbicides can be used to kill these lake weeds? NO
Sure, the use of an approved herbicide can be used to kill your lake weeds. The problem is how do you stop it
f rom killing all the vegetation? Most herbicides are either dragged of f the back of a boat or sprayed on the
surf ace of the water. How can they be controlled to only kill a percentage of the plants and not spread all
over the lake? As soon as the chemical hits the water is just spreads into solution, and goes everywhere…
When a chemical is used to kill lake weeds
that lake is lef t with several problems.
Because of its scorched earth ef f ect the
lake has no ability to use the nutrients that are in the water. Phosphorus and nitrogen f rom f ertilizers and
decaying vegetation supply the lakes plant lif e with necessary nutrients. When there are no weeds in the lake
where does the nutrients go? The weeds that are dying become part of the biomass at the bottom of the lake
which creates the ‘Muck” people talk about when they walk into the water.
Lake weeds gone, but still not swimming..
Why? What happens when the lake can’t absorb the nutrients that it produces, It has to go somewhere.
Algae, the green stuf f starts to grow and about 5 weeks af ter the chemical treatment we are lef t with this
algae blooms f loating into our swimming lanes…
If you like swimming in algae that’s f ine but f or me its worse then weeds, at least with weeds the water is clean.
How to Kill Lake weeds, correctly? Use something that will not kill every lake weed just the ones in the area
you are using… That’s a Lake Bottom Blanket – It kills lake weeds only where you place it and its 100%
