Seasonal minimum releases restarted

Ashokan Release ChannelThe Ashokan Release Channel is being reactivated today at 15 million gallons per day (mgd) for community releases. The current release channel turbidity is 4.4 NTU. Ashokan Reservoir’s east basin is currently spilling over at a rate of 635 mgd. The combined spill and release rate will be maintained below 1000 mgd per the interim release protocol.

The Mount Marion gauge is currently at 16.2 ft river stage and steadily decreasing to 14.9 ft for the forecast period ending May 22 at 8:00am.

Ashokan release volume increasing to 150 MGD

Ashokan Release Channel
NYCDEP will increase flow rate on the Ashokan Release Channel from 10 mgd to 150 mgd today and maintain a draw from the West Basin into the Catskill Aqueduct. This increase is intended to keep reservoir level on target with the CSSO of 95.5% and anticipating a surplus of forecasted inflows. Release rate is expected to stay at 150 mgd through the weekend and will be reevaluated next week. Current storage in the reservoir is 94.3% with a turbidity of 5.1 NTU.

Comment period and public meeting for Ashokan turbidity study

The Draft Scope for the modification of the CATALUM SPDES permit environmental impact statement is available for review at: http://www.dec.ny.gov/lands/79771.html

The Environmental Impact Statement (EIS) will evaluate the potential for significant adverse environmental impacts to occur from implementation of the turbidity control measures proposed to be incorporated into the Catalum SPDES Permit (Turbidity Control Measures).

Written comments on the draft scope will be accepted until the close of business on July 8, 2014. Public scoping session will be held in Ulster County at 3 p.m. and 6 p.m. on May 12, 2014 at the Ulster County Community College Student Lounge, 491 Cottekill Road, Stone Ridge, New York.
