Page "Otisco Lake" Paragraph 5

According to the U. S. Environmental Protection Agency, " the lake is affected by nonpoint source pollution from agriculture ( pesticide and fertilizer use, manure production, and sedimentation resulting from poor tillage practices ), residential land use ( septic systems, lawncare, and construction ), and streambank erosion.

" Currently the lake is experiencing severe problems brought on by zebra mussels which have come into the water via boaters.

Swimmers should wear appropriate footwear as the mussels can be quite sharp.
