What a difference a week makes! Thanks to a few days of rain and continued rain/show showers, our area rivers and streams have received a much-needed boost of volume, causing water levels to return to a more normal flow.
Last Thursday the gauging station on the Beaverkill at Cooks falls recorded a flow of almost 3000 cubic feet per second; on this Wednesday morning the level had receded to 470 cfs, which is just about the same as the average flow of 476 cfs on this date over 102 years of record-keeping.
The East Branch Delaware at Fishs Eddy followed suit, ranging from a high last Thursday of almost 4000 cfs to this Wednesday morning’s reading of 924 cfs, which is just above the average flow on this date of 900 cubic feet per second over 61 years of record-keeping. Water temperatures on the East Branch ranged from a high of 45 degrees F last Thursday to a low of 38 degrees yesterday morning.
The West Branch Delaware at Hale Eddy registered a high flow last Thursday of 900 cfs to a low of 300 cfs yesterday morning. Today’s flow was 316 cubic feet per second, a bit below the 52-year average flow of 389 cubic feet per second. Temperatures on the West Branch ranged from a high of 47 degrees F last Thursday to just about 38 degrees these past three mornings.
Surprisingly, the NYC Reservoir system is still well below average capacity; as of yesterday, December 6, the total storage of the NYC water supply system is just 59.3% full - as compared to the “normal” historic reading of 81.8%. The average Average Precipitation records show that we are still below normal - receiving just 2.86 inches in October as compared to 4.16 inches; in November we received 3.07 inches as compared to 3.72, and so far in December, 0.14 inches as compared to 0.61.
And although the Rondout Reservoir is at 93.2% capacity, our other Catskill reservoirs are not faring as well: Ashokan registers 60.2%; Neversink 56.6%; Pepacton 52.4%; Schoharie 46.5%; and Cannonsville just 25.5% full.
