Memorial Day weekend was one of the warmest we can remember in recent years - with temperatures well into the 90s (and on Saturday, the thermometer on the East side of the house actually recorded 128 degrees in the sun!!!) quite a difference from two weeks previous, when jackets and turtleneck sweaters were still part of the wardrobe.
Possibly due to the sudden hot weather, not many flies were hatching during the day, making it a slow weekend for daytime fly-fishers. Those who stayed on till dark fared somewhat better, finding some March Browns, the smaller Gray Foxes, Blue-Winged Olives, and even some Sulphurs (on the West Branch Delaware) right at dark. A few Green Drakes have been seen as well. Catskill fly fishers will do well using imitations of those flies.
Water levels in our rivers and streams have dropped, and our trees are now fully leafed out; this creates a significant draw on the water table, and the predicted rains for the coming weekend will be welcomed.
On Wednesday, June 1, the Beaverkill at Cooks Falls was recorded as flowing at just 174 cubic feet per second; this is much lower than the average flow of 375 cfs over 102 years of record-keeping. The maximum recorded flow on June 1 was 3090 cfs in 1992; the lowest recorded flow on this date was just 115 cubic feet per second back in 1959. And on the Beaverkill, as well as on the Willowemoc, Blue-Winged Olives, Caddis, March Browns, Gray Fox, Sulphurs, and some Green Drakes have been spotted.
