MARGINAL
Ice conditions present at USGS gauges; water temps near 32°F. Fishable in open water sections but extremely cold—dress accordingly and fish midday warmth windowsDelaware River
Current Hatch Activity
Sparse midge activity on warmer afternoons when temps climb above freezing. Ice shelves line the banks in many sections—fish are holding tight in deep pools and slow seams. Best window is 11am-2pm on sunny days. Use 6X-7X fluorocarbon and expect slow, subtle takes. Zebra Midge #20-22, Mercury Midge #22, and RS2 #22-24 are your best bets. Streamer fishing (Woolly Bugger #8, Sculpzilla #6) can produce in deeper runs.

Quick Reference
400-450 CFS nearly 100% wadeable. 600-800 CFS 60-70% wadeable, very floatable. 1,000-1,200 CFS requires boat. Above 1,500 CFS dangerous for wading.
45-58°F optimal. Tailwater releases from Cannonsville and Pepacton reservoirs keep temps cold. Wild trout thrive.
USGS gauges at Hale Eddy and Fishs Eddy showing ice conditions as of 2/9/2026. Water temp at Hale Eddy reads 32°F (0.2°C). Flows estimated near seasonal averages (~400-560 CFS) but exact readings unavailable due to ice. Directed releases maintain 1,750 CFS minimum at Montague gauge per Supreme Court decree.
Generally excellent clarity. Spring snowmelt and heavy rains can reduce visibility temporarily. The river clears from the dams downstream.
What "Fishable" Means Here
East Coast's premier wild trout tailwater. Clear, cold water and abundant insect life support trophy browns and rainbows. The West Branch is particularly renowned for technical dry fly fishing.
Seasonal Patterns
spring
March through May brings legendary hatches. Hendricksons, Sulphurs, and March Browns provide excellent dry fly fishing. Flows can be high from snowmelt—check conditions.
summer
June through August depends heavily on directed releases. When cold water is released, incredible hatches occur—Coffin Flies, Isonychia, Tricos. Hot summers with low releases can stress fish.
fall
September through November is excellent. Browns get aggressive for spawn. Streamers produce trophy fish. BWOs and October caddis provide consistent dry fly action.
winter
December through February offers solitary fishing on one of the East Coast's best rivers. Midges and small nymphs in slower water. Technical but rewarding for dedicated anglers.
