What is the green floating mass in my lake?
It is probably filamentous algae, sometimes called “pond scum.” This is a common and troublesome aquatic weed that forms dense, hair-like mats. This algae forms on near shore bottom sediments or submerged objects in lakes with good transparency where light reaches the bottom. How do I control algae blooms in my lake? The best thing we can do is to reduce or eliminate the amount of nutrients (phosphorus and nitrogen) from man-made sources such as lawn fertilizers, faulty septic systems, soil erosion, and phosphorus-rich detergents. How do I minimize phosphorus inputs into my lake? Loading excessive nutrients into a lake will speed up its natural eutrophication process. You can minimize inputs of phosphorous by: • ensuring your septic tank/wastewater system is working properly • using liquid dishwasher soap-it has a of the phosphate content of powders. • using phosphorus-free soaps. Septic fields do not break down phosphorus or dilute it. • eliminating the use of synthetic fertilizers on
