Weekend reservoir release related to recreational whitewater event
NYC DEP increased the Ashokan Release Channel flow rate from 15MGD to 150 MGD to mitigate the impact of a NYS DEC requested whitewater release from Shandaken Tunnel Portal this weekend for an event on the upper Esopus Creek sponsored by the Kayak and Canoe Club of New York. Releasing water from the reservoir in advance and during the whitewater release from the tunnel will mitigate any potential spills from the reservoir since reservoir level is close to 100% capacity.
