Reservoir Release Workshop

The Lower Esopus Ashokan Reservoir Release Workshop
Wednesday, April 11, 2012
6:30 – 8:30 pm
@ Cornell Cooperative Extension of Ulster County
In their new Kingston Plaza location at 232 Plaza Road
RSVP cbalmer@rcapsolutions.org

Thank you to all who were able to attend the LEWP-sponsored Lower Esopus Positive Action Workshop at the end of January. We are in the process of confirming and revising the priority projects that were identified during the workshop. One of the major activities we have been pursuing since then is the removal of log/ debris jams along the stream. LEWP is helping coordinate a funding application that is being submitted by Ulster County Soil and Water Conservation District in early April. This funding is for debris sites that did not meet the imminent threat criteria required for funding through the Emergency Watershed Protection Program.

For many of you, the biggest concern is with water quality and quantity associated with releases from the Ashokan Reservoir. LEWP is holding a workshop to provide updates on this issue, including details of NYSDEC/ NYCDEP’s Interim Release Protocol; and to document your concerns and identify community action steps. Please save the date and email RSVP to Candace Balmer cbalmer@rcapsolutions.org.

Ashokan Release Channel Operations 3/2/12

The Ashokan Release Channel was increased today from 80 to approximately 120 MGD. The increase was made in one 40 MGD increment at 2:35 PM. The increases were made in response to additional snowpack in the Ashokan watershed and to offset a decrease in the diversion from the reservoir into the Catskill Aqueduct. The increased releases will help maintain the void in the reservoir for flood mitigation according to the Conditional Seasonal Storage Objective outlined in the Interim Protocol. Turbidity levels for the releases are currently less than 30 NTUs.

Volume of Ashokan releases decreased today

The Ashokan Release Channel was decreased today from 600 MGD (Million Gallons per Day) to approximately 300 MGD. The decreases were made in approximately 40 MGD increments starting at 11:30AM and completed at 3:00PM.

After months of high volume releases, the Ashokan Reservoir finally reached the Conditional Seasonal Storage Objective of 90% capacity, which allows for a 10% void for flood mitigation.

LEWP comments on interim protocol

The Lower Esopus Watershed Partnership in cooperation with Riverkeeper prepared comments on the Interim Ashokan Release Protocol. The comments from municipalities and other stakeholders along the lower Esopus were compiled into a letter and submitted to the DEC. The letter calls for a deadline by which time the interim protocol would be replaced by a SPDES permit. Limits on turbidity are also recommended. The letter is available here for download as a PDF.

Ulster County and Riverkeeper petition DEC

Ulster County and Riverkeeper submitted a formal petition to the New York State Department of Environmental Conservation concerning the releases from New York City’s Ashokan Reservoir. The petition calls upon DEC to meet its regulatory obligations and uphold water quality standards in the lower Esopus Creek. The DEC is criticized for relying on the Interim Protocol to authorize releases instead of using the SPDES permit program. In October, DEC issued an Interim Ashokan Release Protocol to govern discharges from the Ashokan Release Channel. Unlike a SPDES permit, the interim protocol did not contain any formal provisions for environmental review or public comment. The petition from UC and Riverkeeper reminds DEC of requirements spelled out in state Reservoir Release Regulations.
