The Ashokan Release Channel is currently being increased from 10 to approximately 300 MGD in 20 to 40 MDG increments, starting at 8AM this morning. The final step is scheduled for 3:30PM. The current release channel turbidity is 8.4 ntu.
The Ashokan Release Channel is being decreased today from 320 to approximately 10 MGD. The decreases have been executed in 20 to 40 MGD steps, starting at 9:30AM this morning with the final step scheduled for 5:30PM this evening.
The current release channel turbidity is 10.30 NTU.
Since the NYSDEC failed to include the lower Esopus Creek on the list of impaired waters, the EPA took action to have the creek added to the list for excessive turbidity. The EPA announced its action in a letter to the New York State Department of Environmental Conservation regarding Lower Esopus Creek, stating:
After considering all submissions and in accordance with the Clean Water Act
and EPA regulations and guidance, the EPA has concluded that current and available information
indicate that New York State’s narrative water quality standard for turbidity is exceeded in the Lower Esopus Creek and that 303(d) listing for this portion of the creek is therefore necessary.
The listing means that the EPA recognizes that prolonged releases of turbid water from the Ashokan Reservoir has impaired the stream and that the state must come up with remedies to address the situation. The rationale for the EPA’s listing is detailed in supporting materials which accompanied the letter, provided in PDF format here:
The Ashokan Release Channel was decreased today from 480 to approximately 440 MGD. The decrease was made at 10:20AM.
The current release channel turbidity is 9.50 ntu.
The Ashokan Release Channel was decreased today from 600 to approximately 480 MGD. The decreases were made in three 40 MGD steps. The first decrease was at 2:45, the second at 3:15PM, and the third at 4:45PM.
The current release channel turbidity is 9.70 ntu.
The exploration of and training on the Lower Esopus digital watershed sub-basin mapping tool has been pushed back 1 week.
Originally scheduled for Jan 15th, the workshop and training will now be on January 22nd, from 9am til noon.
The event is taking place at Cornell Cooperative Extension offices in the Kingston Plaza.
You are welcome to attend!
Workshop: TUESDAY, JANUARY 22nd, 9 am-12 noon
The digital sub-basin maps were created by the CCEDC GIS Lab in coordination with Hudsonia Ltd. for the Lower Esopus Watershed Partnership. The New York State Department of Environmental Conservation provided funding for this project from the Environmental Protection Fund through the Hudson River Estuary Program in partnership with the New England Interstate Water Pollution Control Commission.
The Ashokan Release Channel was increased this evening from 400 to approximately 600 MGD. The increases were made between 5:30 and 7:30 PM in increments of 40 MG each.
The current release channel turbidity is 13.5 ntu.
The Ashokan Release Channel was decreased today from 600 to approximately 400 MGD. The decreases were done in 40 MGD increments and completed at 2:30PM.
The current release channel turbidity is 13.40 ntu.
The Ashokan Release Channel was increased from 400 to approximately 600 MGD starting at 11:00AM finishing at 1:00PM. The increase was made in 40 MG increments every 1/2 hour. The current release channel turbidity is 11.9 ntu. The reservoir level is 91.7%, and the releases are intended to reduce the level to the Conditional Season Storage Objective of 90%.
The Ashokan Release Channel will increase today from 0 to approximately 400 MGD. The increases will be made gradually in increments of 20 to 40 MGD starting at 7:30AM and finishing at 4:00PM.
The current release channel turbidity is 8.10 ntu.
