Proposed changes to Ashokan release protocol

NYCDEP has requested a modification to the Ashokan Reservoir Interim Release Protocol (IRP).  High level changes include:

  1. the removal of the protocol to allow for Operational Releases;
  2. Modification of the Spill Mitigation Release Protocol which would require DEP to reduce the discharge to the Community Release levels should the turbidity of the Release Channel discharge meets or exceeds 20 NTU.  However, language has also been included to allow Ulster County to submit a written request to DEC and DEP for DEP to continue or restart discharge mitigation releases to achieve the void target as identified in the Conditional Seasonal Storage Objective (CSSO) when the turbidity meets or exceeds 20 NTU.

Comments can be submitted before November 2nd to:

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.
