Skaneateles Lake water quality monitoring intensifies as 2026 summer recreation season begins
Syracuse’s primary unfiltered drinking water source remains one of the cleanest of the Finger Lakes.
Skaneateles Lake, the 16-mile-long lake on the western edge of Onondaga County and the eastern edge of Cayuga County, holds water that has been the primary unfiltered drinking water supply for the City of Syracuse since 1894. The lake’s clarity, depth, and watershed characteristics qualified it for an Environmental Protection Agency Filtration Avoidance Determination, one of only a handful of public water supplies in the United States that meets the strict standards required to operate without conventional water treatment filtration.

The 2026 summer recreation season has just begun. The Village of Skaneateles, on the lake’s northeastern shore, is one of the most-visited Finger Lakes village centers each summer, and the lake itself supports a substantial recreational boating and fishing economy.
What the monitoring program covers
The City of Syracuse Department of Water, in cooperation with the New York State Department of Health and the EPA Region 2 office, operates a continuous monitoring program for the Skaneateles watershed. The program includes regular intake sampling at the lake’s western shore intake structure, tributary monitoring on the major streams that feed the lake, and an agricultural best-management-practices program for the working farms in the watershed.
The watershed protection program
The Skaneateles Watershed Agricultural Program, funded in part by the City of Syracuse and administered through the Onondaga County Soil and Water Conservation District, works with farm operators in the watershed on nutrient management, streambank stabilization, and cover crop adoption. The agricultural community in the watershed includes more than 200 working farms across Onondaga, Cortland, and Cayuga counties.
What the recreation calendar looks like
The Village of Skaneateles operates Clift Park on the lake’s northeastern shore, including a swimming area, a fishing pier, and seasonal boat launch. The New York State Department of Environmental Conservation maintains additional access points around the lake. The Skaneateles Festival, the village’s classical music festival, runs through August.
Where to track water quality information
The City of Syracuse Department of Water publishes weekly intake water quality reports during the summer monitoring season. The Department of Health Onondaga County office publishes recreation-water bacteria and bloom advisories. The New York State Department of Environmental Conservation maintains the statewide harmful algal bloom notification system.
