the effect of goose poop on lakes
would large amounts of goose poop adversely affect the water of a lake and if aeration was used on the lake would it offset the poop and is aeration good to do in the winter if it keeps the lake from freezing which attracts large numbers of geese to the only open water in the area. The lake is in Ft Collins, Warren Lake.
Larimer County Colorado
If the lake was landlocked and did not have an inlet or outlet, then the buildup of goose poop would most likely be a problem. The goose poop would cause the dissolved oxygen in the lake to be consumed and fish would eventually die. Warren lake is a reservoir that was built in the late 1800's that has an inlet and and an outlet, where water can easily flow into and out of the lake. Geese have been congregating at the lake for over 100 years, and it has been able regenerate itself each year. The accumulation of poop on the ice in the winter may appear really nasty, however it will eventually decompose and get flushed from the lake when the ice melts. You could install an aerator, however there should be enough water flowing through the lake to prevent the buildup of feces or their byproducts.
