Beaverkill and Willowemoc Fishing Report: July 31, 2026

The Beaverkill and Willowemoc are falling from the flood pulse, but the 9 AM refresh and current Delaware-system context still point to high, off-color water and unsafe wading.

Quick Summary

Skip the Beaverkill and Willowemoc for trout wading this morning. USGS showed the Beaver Kill at Cooks Falls at 1,740 cfs and 4.51 feet, while Willowemoc Creek near Livingston Manor was 522 cfs, 3.26 feet, and 60.4 F near the 9 AM refresh. Those readings are falling, but a current Delaware-system report still has both freestones high and very off-color. Let the rivers drop, clear, and stabilize before trying to match hatches.

Weather

For Roscoe and Livingston Manor, the National Weather Service forecast calls for sun, a high near 79 F, and northwest wind around 2-6 mph. Tonight should be mostly clear with patchy fog late, and no active NWS alerts were posted for the checked zones during the morning run. The lack of new rain helps the hydrograph continue down, but today's weather does not remove the immediate post-flood wading hazards.

River Notes

The Beaverkill and Willowemoc are moving in the right direction, but they are not ready for a normal trout report. The Cooks Falls gauge is still carrying a large volume of water, the Willowemoc remains elevated, and current Delaware-system reporting describes both as very off-color. High water after a flood can hide altered slots, soft banks, woody debris, and undercut edges. The Beaverkill's Horton Brook thermal refuge closure also remains in place from Iron Bridge at Horton downstream to the first Route 17 overpass, where angling is prohibited July 1 through August 31.

Hatch Activity

Official gauges do not report hatches. Late-July Catskill timing still supports olives, sulphurs, tan caddis, Isonychias, Light Cahills, and terrestrials once water levels recover, but hatch matching should wait until the rivers are safely wadable and clear enough to read.

HatchSizeNotes
Blue Winged Olive16-22Likely relevant after flows settle, especially in shade or cloud cover
Sulphur16-20Seasonal option for the next safe evening or soft-edge window
Tan Caddis16-18Carry for recovered riffles and pocket seams
Isonychia10-14Useful after larger riffles become safe and readable again
Light Cahill14-16Evening pattern for later, not a reason to enter high water
Ants and Beetles14-20Summer bank option once flows and temperature are suitable

Recommended Flies

CategoryFlySizeNotes
OtherNot reportedNot reportedNo fly choice makes the Beaverkill or Willowemoc a responsible wading recommendation at this morning's flows
DryBWO Comparadun or CDC Dun16-22Carry for the next safe cloudy or shaded window
DrySulphur Sparkle Dun or Comparadun16-20Seasonal pattern after clarity improves
DryElk Hair Caddis or X-Caddis16-18Good recovered-riffle option once levels settle
DryAnt or Beetle14-20Summer bank pattern for later lower water
WetSoft Hackle Pheasant Tail or Hare's Ear14-18For soft seams after the water drops; not a high-water recommendation today

Tactics

The right tactic is to wait. Do not wade the Beaverkill or Willowemoc today, do not cross side channels, and do not fish from soft banks that were recently under floodwater. If you check conditions in person, stay back from fast edges and treat any off-color water as a reason to leave. Recheck both gauges later, then confirm clarity and temperature before targeting trout. If you need to fish today, choose a safer stillwater, a warmwater option away from flood-affected banks, or the West Branch tailwater only where footing, weather, and water temperature remain suitable.
