NEW-YORK RESERVOIR REPORT

Last Updated: January 2, 2026

New York's reservoirs and dams play a critical role in water storage and management across the state, with current observations pointing to a mix of normal and abnormal conditions in various locations. Indian Lake near Indian Lake, NY, is showing water levels nearly consistent with the average at 1645 feet, just one inch below its average mark. Similarly, Onondaga Lake at Liverpool and Lake George at Rogers Rock are both maintaining water levels close to their respective averages of 363.08 feet and 319.25 feet. First Lake at Old Forge is slightly above its average of 1705.6 feet. However, Owasco Lake near Auburn is experiencing lower than average water levels, sitting at 709 feet compared to its average of 711.22 feet. Stillwater Reservoir near Beaver River is also registering a noticeable dip with the current elevation at 1666 feet, significantly lower than its average of 1671.89 feet. An anomaly is present with Skaneateles Lake at Skaneateles, where the temperature reading is missing, indicated by an outlier value of -999999 degrees Celsius; this is likely a data error that requires correction.

The discrepancies in water levels could be attributed to several factors, including variations in snowpack melt, precipitation, and river flows affecting the catchment areas. Owasco Lake and Stillwater Reservoir's lower levels might suggest reduced snowpack or lower-than-expected inflow for this time of year. Conversely, the slightly elevated level at First Lake could be the result of recent precipitation or increased runoff. Without specific data on snowpack or river flows, it's challenging to pinpoint the exact cause of these abnormalities. Cross-referencing with additional hydrological data, weather patterns, and historical trends would be essential to provide a more comprehensive understanding of the situation. It's also worth noting that dam and reservoir management may adjust water levels intentionally for various reasons, including maintenance, flood control, and ecological concerns, which could account for some observed variations. The missing data for Skaneateles Lake highlights the importance of accurate monitoring and the need for timely resolution of data discrepancies to ensure reliable management of water resources.

New York State has several major reservoirs and dams, including the Ashokan Reservoir, the Cannonsville Reservoir, and the Pepacton Reservoir. These reservoirs are fed by several streams, rivers, and creeks, including the Esopus Creek, the West Branch Delaware River, and the Beaver Kill. The hydrology in the area is affected by the snowpack and mountains, which can significantly impact streamflow and water levels in the reservoirs. Record levels have been observed in some reservoirs in the past, but drought conditions have also been a concern, particularly during the summer months. Seasonal trends often show lower water levels in the fall and winter, with increased flows during the spring snowmelt and summer rainfall. Overall, these reservoirs play a vital role in providing clean drinking water to millions of New Yorkers while also providing opportunities for recreation and tourism.
