Ashokan release increased to 600 MDG

The Ashokan Release Channel is currently being increased today from 300 to approximately 600 MGD in 40 MDG increments. The current release channel turbidity is 8.0 ntu.

To continue with discharge mitigation in accordance with the interim release protocol, DEP has further increased flow rates in the Ashokan Release Channel in order to maintain a 10% void in the reservoir.

These discharge mitigation releases are expected to continue for approximately one week but may change with reservoir operating and downstream conditions.

EPA adds lower Esopus to list of impaired waters

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:

Watershed mapping workshop postposed to Jan 22nd

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.
