The Chautauqua County NY Department of Planning and Economic Development, in partnership with the Chautauqua Lake Management Commission, oversaw development of a watershed management plan for the lake. The plan, completed in September of 2010, characterizes historic and current conditions related to the flow of water, sediment, and nutrients from the watershed to the lake. It makes numerous recommendations for ways that landowners, visitors, and municipalities can reduce the flow of those materials from the watershed in the long-term. Though the Plan was written for Chautauqua Lake, many of the recommendations are applicable throughout the Conewango Creek watershed.
