The Beaverkill is easing back down towards a more regular or average flow for this time of year. At this writing, Friday morning, the river is flowing at 403 cubic feet per second, which is still above the average flow for this date of October 26 of 292 cfs over 104 years of record-keeping. The highest recorded flow on this date was 3210 cfs in 2009; the lowest flow recorded on October 26 was just 29.0 cubic feet per second back in 1965.
Temperatures ranged from a low of 42.0 degrees this morning to a high of 49.0 degrees last Saturday afternoon.
Late-season fly hatches are still tiny Blue-Winged Olives and midges (sizes #18 and smaller) Isonychias and various sizes and colors of Caddis flies. Fishing below the surface with nymphs and streamers seems to be effective especially when the water is high and discolored.
The East and West Branches of the Delaware are still very high for this time of year - the former at Fishs Eddy coming in at 1420 cfs as compared to the average flow for today’s date of 694 cfs. The highest recorded flow on this date was 4770 cfs in 2009; the lowest flow recorded on October 26 at Fishs Eddy was just 123.0 cubic feet per second back in 1964.
And the West Branch at Hale Eddy measuring 1640 cubic feet per second as compared to the average of 447. The highest recorded flow on this date was 3130 cfs in 1977; the lowest flow recorded at Hale Eddy on October 26 was just 30.0 cubic feet per second back in 1964.
Water temperatures for the East Branch were in the 40s all week, with the West Branch a bit warmer, reaching into the 50s for most of the week.
Of course, being Tailwater fisheries, the East and West Branches of the Delaware are affected by the NYC Reservoir release program. At this writing, the Catskill reservoir system is well over its average storage capacity - being 92% full, with the average or ‘normal’ capacity at just 75.8%. No surprise there, as the amount of rainfall received in August and September was well above the average - in August the rainfall was more than double the average historic amount - 8.99 inches compared to 4.15 inches in the month of August; and in September, another huge disparity in rainfall - with 7.69 inches of rain having fallen compared to the average historical level of 4.63 inches. We aren’t finished with the month of October yet, but rainfall seems to be more normal - as of October 26, 3.1 inches of rain fell, with the historical average for the month of October being 3.28 inches.
On an individual basis, Pepacton Reservoir is 97.7% full, at 140.2B gallons capacity; Cannonsville Reservoir is 92.3% full, with 95.7B gallons capacity of water. The Neversink Reservoir is just about ready to spill, being 99.9% full and more heavy rains predicted this weekend - it’s capacity is 34.9B gallons; Rondout Reservoir is 95.9% full with 49.6B gallon capacity; and Ashokan Reservoir is just 75.3% full, with 122.9B gallon capacity.
