Statement from NYC Environmental Protection Deputy Commissioner for
Water Supply Paul Rush On Tomorrow’s Activation of the Ashokan Waste Channel

“Following a request from the Town of Hurley, and with the agreement of the State Department of Environmental Conservation and Ulster County, DEP will activate the Ashokan Reservoir Waste Channel starting tomorrow morning for up to one week,” said Deputy Commissioner Rush. “Activating the waste channel is being undertaken in response to a snow storm expected to start tonight that will enhance the potential for higher flows due to snowmelt in the coming days. These releases will increase the reservoir’s ability to capture runoff by creating a void in the west basin of the reservoir, providing enhanced flood protection for communities south of the Ashokan Reservoir along the lower Esopus Creek. This will also provide an additional benefit of protecting water quality by reducing the amount and likelihood of spillage from the more turbid west basin into the higher quality east basin, thereby protecting the drinking water of approximately 8 million New York City residents and the roughly 160,000 residents of towns that rely on the Catskill Aqueduct such as New Paltz and High Falls in Ulster County, and New Windsor and Cornwall in Orange County.”

The latest information from the National Weather Service on the coming storm indicates that the reservoir could spill, increasing the potential for flooding in the lower Esopus. The action agreed to today will release up to 600 million gallons per day from the Ashokan Reservoir for the next week, depending on existing flows in the lower Esopus Creek. These releases will be discontinued if the stream gage on the lower Esopus Creek located at Mt. Marion is within one foot of flood action stage (18 feet) and the National Weather Service forecasts potential flooding.

The waste channel is a concrete canal used to convey water released in a controlled manner from the reservoir through the upper and lower gate chambers to the Little Beaverkill stream and the lower Esopus Creek. Located in Ulster County, the Ashokan Reservoir is approximately 13 miles west of Kingston and 73 miles north of New York City. It was formed by the damming of the Esopus Creek, which eventually flows northeast and drains into the Hudson River. The reservoir holds 127.9 billion gallons at full capacity and was opened in 1915.

DEP manages the city’s water supply, providing more than 1 billion gallons of water each day to more than 9 million residents, including 8 million in New York City, and residents of Ulster, Orange, Putnam and Westchester counties. New York City’s water is delivered from the Catskill, Delaware, and Croton watersheds that extend more than 125 miles from the City, and comprises 19 reservoirs, and three controlled lakes.

Flood-mitigation release announced for Ashokan

Statement from NYS Environmental Conservation Commissioner Joe Martens and NYC Environmental Protection Commissioner Cas Holloway On Today’s Activation of the Ashokan Waste Channel

“Earlier today, after close consultation with and agreement from Ulster County, the State Department of Environmental Conservation, the New York State Department of Health, and the Environmental Protection Agency, DEP activated the Ashokan Reservoir Waste Channel for up to one week,” said Commissioner Holloway. “Activating the waste channel will increase the reservoir’s ability to capture runoff from intense storms by creating a void in the west basin of the reservoir ahead of tonight’s forecasted storm, providing enhanced flood protection for communities south of the Ashokan Reservoir along the lower Esopus Creek. This action, which reduces the amount of spillage from the more turbid west basin into the higher quality east basin, will also help protect the drinking water of approximately 160,000 residents of towns that rely on the Catskill Aqueduct such as New Paltz and High Falls in Ulster County; New Windsor and Cornwall in Orange County; several towns in Westchester County, including Yorktown and Ossining; as well as the residents of New York City.”

“We concur that activation of the Ashokan diversion channel is appropriate at this time to limit adverse flooding in communities along the Lower Esopus Creek and reduce turbidity in water flowing toward the New York City drinking water system,” said Joe Martens, DEC Commissioner. “Flood ‘action levels’ in the Lower Esopus will be actively monitored and adjustments to the diversion channel output will be made as needed.”

The latest information from the National Weather Service on the coming storm indicates that the reservoir could spill, increasing the potential for flooding in the lower Esopus. The action agreed to today will release up to 600 million gallons per day from the Ashokan Reservoir for the next week, depending on existing flows in the lower Esopus Creek. These releases will be discontinued if the stream gage on the lower Esopus Creek located at Mt. Marion is within one foot of flood action stage (18 feet) and the National Weather Service forecasts potential flooding. This is the first activation of the Ashokan Reservoir release since February 1, 2011.

DEP reopens Ashokan waste channel

For the first time since closing the Ashokan waste channel in February, the NYC DEP is reopening the waste channel to make a void in the West Basin to capture anticipated stormwater runoff. See statement from NYS DEC and NYC DEP below.

DEC action against DEP

NYS Department of Environmental Conservation filed a Notice of Hearing and Complaint against the New York City Department of Environmental Protection citing unauthorized use of the Ashokan Waste Channel and failure to comply with its Catalum SPDES Permit. The DEC seeks $2.6 million in civil penalties from the DEP and an independent study of the impacts from turbid releases to the Lower Esopus. The DEC is also requiring an operating plan and parameters for use of the Waste Channel for the “beneficial interest” such as flood control for downstream communities. The entire complaint is available for download as PDF:

DEP organizing a technical committee for future releases

As a part of its obligation to assess impacts from recent turbid releases and its promise to conduct clear water releases in the future, NYC DEP announced that it is organizing a technical committee within the existing Ashokan Releasee Working Group to focus on these issues. This committee will be given the tasks of developing release protocols and impact assessments for operation of the Ashokan Waste Channel. John Vickers of the DEP made the announcement at the recent LEWP Informational Seminar in Saugerties. Bill Kimble of the Daily Freeman reported on the meeting and the announcement. The technical committee will include DEP personnel and representatives from downstream municipalities, LEWP, Ulster County, Riverkeeper, Hudsonia, NYPIRG, Ashokan Foundation, Federated Sportsman of Ulster County, NYS DEC, US EPA, and NYS DOH.

LEWP hosted public information forums on turbidity

On Thursday evening, February 10th, the local press and area residents attended an informational seminar hosted by the Lower Esopus Watershed Partnership and the Town & Village of Saugerties. Formal powerpoint presentations were made by representatives of LEWP, Ulster County, and DEP. A representative of the DEC was also present to answer questions as part of a panel. In the audience were elected officials including Mayor Bill Murphy of Saugerties, Town Supervisor Greg Helmoortel and a staff member from the office of Assemblyman Pete Lopez. Residents who owned property or businesses along the creek ask questions and expressed their concerns about the prolonged turbid releases from the Ashokan Reservoir. The Daily Freeman reported on the meeting. This was the second informational seminar this week focusing on creek turbidity issues. The first was held on Tuesday, February 8th at Town Hall in the Town of Ulster.

DEP posted results of follow-up water testing

After concluding three days of clear water flushing of the Lower Esopus Creek, DEP collected water samples at three sites long the creek: the waste channel, Marbletown Recreation Park, and Saugerties Village Beach. The samples were tested for turbidity, suspended solids, pH and conductivity to compare with samples collected during turbid water releases. Review water sampling results and read a statement from Commissioner Cas Halloway in DEP Press Release.

Ice may move when lower flows begin

Ice on the creek that has formed over a high volume flow might be going through some adjustments when lower flows begin.

Beginning at 1pm on Friday January 28, 2011, the high-volume flows from the Ashokan Release Channel switched from the turbid West Basin to begin releasing cleaner water from the East Basin. This will continue for three days to help flush out turbidity from the Lower Esopus Creek, after which lower flows are expected. As water levels drop, the creek ice is expected to readjust, which may cause cracking and ice instability.

The clear water flush of the creek is a short term solution, but it is a first step to having clean water releases for stream health. This will need to be followed up with monitoring to understanding the harm done to the Lower Esopus Creek and downstream communities by the prolonged, high-concentration turbid water releases from the West Basin of the Ashokan Reservoir.
