Received this afternoon:
Hi, folks. I’m following up from my note last week with a quick update on New York City’s reservoir storage and release plans.
Because of rain and snowmelt, the past three days have brought a combined total of 17 billion gallons of runoff into Cannonsville and Pepacton. While we’re happy to see the reservoirs refilling, DEP must also strive to meet a storage objective in its reservoirs this time of year. The FFMP says we should aim to keep storage no higher than 93 percent as of now.
That is why we began larger releases from Cannonsville Reservoir last week. We have been releasing 1,500 cubic feet per second (975 mgd) from Cannonsville into the West Branch, and we plan to continue that for at least the next week. We will not be ramping down this weekend as previously planned. Doing so would cause the reservoir to fill beyond the objective and cause it to spill earlier.
We have also increased releases from Pepacton Reservoir. We are currently releasing about 835 cubic feet per second (450 mgd) into the East Branch. That will likely continue for at least the next week as well.
I hope this information is helpful. And, as always, please feel free to email or call with any questions.
Best,
Adam Bosch
