The Delaware River in Roscoe meanders through the picturesque Catskills of upstate New York, featuring clear, flowing waters ideal for wading and targeting trout in riffles and deep pools.

Overall Fishing Conditions

Fishing conditions on July 31, 2025, should be moderate with cooler temps around 72°F and light NE winds helping to keep things calm, but low flows (many at 70-90% below average) and warmer water (up to 77.4°F in places) might make trout sluggish or spooky, especially with forecasted rain potentially muddying waters later—overall, I'd rate it a 6 out of 10 for solid opportunities if you fish smartly.

Insect Hatches and Their Timing

Late July hatches will likely include tricos and terrestrials like ants and beetles emerging in the morning and evening; expect increased activity around midday if the waxing crescent moon (42% illumination) draws bugs, but rain could delay or suppress hatches until after storms pass.

Species to Target

Focus on brown and rainbow trout, which are abundant in the river's deeper runs and pools; smallmouth bass might also be active in warmer sections, making them a fun secondary target if trout are less responsive.

Top 5 Fly Patterns to Use

• Parachute Adams in size 14-18 for versatile dry-fly action during hatches.
• Elk Hair Caddis in size 14 for evening terrestrials.
• Beadhead Pheasant Tail nymph in size 16 for subsurface fishing in low flows.
• Trico Spinner in size 20-22 for early morning rises.
• Woolly Bugger in black or olive, size 8, for tempting larger trout or bass in deeper water.

Best Times of Day to Fish

Early morning from dawn until 10 AM when water is calmer and hatches start; late afternoon to dusk around 6-9 PM as the moon rises, offering better visibility and feeding windows before potential evening rain hits.
