Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Why do Big Lakes not have Filamentous Algae issue?

Matt:

Late to the discussion here but here's my take:

I believe it's a combination of things, not one thing specific. Nutrient loading and water clarity.

I agree that it's not current, as I have to treat man-made streams/waterfalls for Filamentous Algae (FA) too.

It will be interesting to see what happens to the local lake this year. They treated it with Fluridone last year (all 365 acres of it) for Eurasian Water Milfoil and Curly Leaf Pondweed. Typically the majority of the shoreline out to 200' would be completely choked off by EWM, and if the water clarity allowed it, CLPW would grow in water up to 12' deep.

After the lake was treated, the lake had it's typical algae bloom and all was good. We'll see if FA shows up this Spring.
