Catskills, New York
Beaverkill-Willowemoc Fishing Report: July 15, 2026
The Beaverkill-Willowemoc remains a warm-water caution report, with Cooks Falls above 72 F this morning and current local context still pointing trout anglers toward cold tailwater rather than low freestone water.
- Status

Quick Summary
The Beaverkill-Willowemoc system remains temperature-limited trout water. USGS showed the Beaver Kill at Cooks Falls at 139 cfs and 72.7 F during the 9 AM refresh, while Willowemoc Creek near Livingston Manor was 29.6 cfs and 66.2 F. Current Catskills reporting also points anglers away from the freestones and toward cold tailwaters during this heat pattern. The responsible trout recommendation is to rest the Beaverkill, treat any Willowemoc attempt as a short thermometer-first dawn check only, and use the cold West Branch Delaware or another release-influenced option for a real trout session.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Tough and temperature-limited for trout; the Beaver Kill was 72.7 F during the 9 AM USGS refresh |
| Flow | 139 cfs at Cooks Falls on the Beaver Kill; 29.6 cfs near Livingston Manor on the Willowemoc |
| Gauge Height | 1.32 feet at Cooks Falls; 1.88 feet near Livingston Manor |
| Water Temp | 72.7 F on the Beaver Kill and 66.2 F on the Willowemoc during the 9 AM USGS refresh |
| Clarity | Not reported by official gauges; low summer freestone flow and warm water are the controlling details |
| Trend | Falling and low on both gauges versus yesterday morning |
| Best Window | Rest the Beaverkill for trout; thermometer-first at dawn only on any shaded Willowemoc reach, then move to cold tailwater |
| Best Method | Do not press warm trout water. Fish cold release water instead, or choose non-trout warmwater options |
| Wadeability | Good from a footing standpoint, but temperature controls whether trout fishing is responsible |
Weather
For Roscoe and Livingston Manor, the National Weather Service forecast calls for haze and areas of smoke, a high near 86 F, and northwest wind around 10 mph with gusts as high as 21 mph. Tonight is forecast partly cloudy with areas of smoke and a low around 62 F. The heat-advisory wording has eased from yesterday, but low freestone water that starts warm in the morning will not get much help from a sunny, hazy, mid-80s afternoon.
River Notes
The Beaver Kill is already above the trout-stress line and should be left alone for trout today. Cooks Falls at 72.7 F in the morning leaves no room for safe catch-and-release fishing as the day warms. The Willowemoc gauge is cooler, but 29.6 cfs is low and individual pools can warm quickly. If you check a shaded Willowemoc reach and it is safely below 68 F, keep the session short, land fish quickly, skip photos, and stop as soon as temperatures climb. Current local context also repeats the summer Horton Brook thermal closure on the Beaverkill, from Iron Bridge at Horton downstream to the first Route 17 overpass, where angling is prohibited July 1 through August 31.
Hatch Activity
The Catskills summer hatch mix still belongs in the box, but today it belongs on cold water rather than warm Beaverkill trout. Expect sulphurs, olives, Isonychias, summer Cahills, tan caddis, yellow sallies, terrestrials, and rusty spinners to matter only where water temperatures remain safe. Do not chase risers in water near or above 68 F.
| Hatch | Size | Notes |
|---|---|---|
| Blue Winged Olive | 18-22 | Relevant on cold tailwater or verified cool shaded water, not warm Beaverkill pools |
| Sulphur | 16-20 | Better matched on cold release water today than on warming freestone reaches |
| Light Cahill | 14-16 | Carry for colder alternatives and evening water only if temperatures remain safe |
| Isonychia | 10-12 | A useful searching bug on cold riffle edges and tailwaters |
| Tan Caddis | 16-18 | Pupa and soft hackles can work where water temperatures stay safe |
| Yellow Sally | 14-16 | Worth having for cold broken water |
| Ants and Beetles | 14-20 | Good summer bank patterns, but only where trout water is cold enough |
| Rusty Spinner | 14-20 | Skip the freestone spinner game unless water is safely below 68 F |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | BWO Comparadun or CDC Dun | 18-22 | Use on cold tailwater or verified safe water only |
| Dry | Sulphur Comparadun or Sparkle Dun | 16-20 | Better fit for cold release water today |
| Dry | Light Cahill or Parachute Adams | 14-16 | Visible searching dry for colder alternatives |
| Dry | Isonychia Parachute | 10-12 | Prospecting fly where temperatures are safe |
| Dry | Yellow Sally | 14-16 | Cold riffle option when stoneflies are active |
| Dry | Ant or Beetle | 14-20 | Summer bank option for cold water |
| Dry | Rusty Spinner | 14-20 | Only for evening water verified below the trout-stress line |
| Nymph | Pheasant Tail or Frenchie | 14-18 | For cold-water alternatives or verified safe freestone water |
| Nymph | Isonychia Nymph | 10-12 | Use on cold riffle edges and seams |
| Wet | Soft Hackle Pheasant Tail or Partridge and Yellow | 14-18 | Useful where trout water is cold enough to fish responsibly |
| Nymph | Tan Caddis Pupa | 16-18 | Dropper option for colder water |
Tactics
Make the thermometer the first tool out of the pack. The Beaver Kill should be rested for trout at the reported morning temperature. On the Willowemoc, only consider a short early check if the exact reach is safely below 68 F, and stop before the water climbs. Use stronger tippet where practical, keep fish in the water, and skip photos. For a normal trout outing, drive to cold release water instead of trying to make low freestone water work through a warm July day.
