Oswego River and Finger Lakes Watershed

Including Otisco, Skaneateles, Owasco, Cayuga, Oneida, Seneca, Keuka, Canandaigua and Canadice Lakes; Oneida River, Clyde River, Cayuga Lake Tributaries and Seneca Lake Tributaries

High Flow:

• Keuka Lake Outlet is flowing much above normal this week, 315% above mean at 266 cfs
• Canadaigua Outlet is also flowing over the 90^th percentile, 464% above mean, 301 cfs

HABs: From the Fall 2020 Water Bulletin, Newsletter of the Community Science Institute, we get a detailed picture of water quality in the Finger Lakes region, including specific toxin levels (microcystin and anatoxin-A) While we have previously reported that the pattern of release of these cyanotoxins is still not well understood, there are patterns emerging in the distribution of the higher toxicity producing blooms.

The period of activity for observed HABs in Finger Lakes ranges from June to October, where last season, the peak number of blooms occurred in September, and the concentration of toxins reached as high as 1556.7 micrograms per liter (Cayuga Lake), 398 x the safe limit for recreational water. 

Knowing when toxins are present in the water is important for recreational users, as even the spray from a boat motor can expose people to the toxins associated with skin rash, nausea and other health effects.
