Otisco Lake is one of the smaller Finger Lakes to the east of Rochester, and the southwest of Syracuse. The lake is 5.4 miles long and about 60 feet deep at its greatest depths.
The lake is very popular during the summer months, as many people enjoy swimming, fishing and boating. During the winter months, good ice fishing can be expected as well.
Lately, the lake has experienced problems with zebra mussels that were brought in on other boats. Due to these zebra mussels, swimmers should take caution and wear the proper footwear. A causeway across the lake was built to carry a road, flooded when the dam raised the level. The road no longer is used. A break in the causeway allows boats to pass between upper and lower parts of the lake. 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.
