DELAWARE RIVER FLY FISHING REPORT

January 18, 2026 — Tailwater trout, winter midges and tight presentations

Report Date: January 18, 2026  |  Next Update: January 25, 2026

Current River Conditions

Cold-water winter fishing is in effect. The Delaware is producing winter eats—midges, sparse baetis and deep-holding trout. Aim for subtle presentations and be mindful of slick banks and icy access.
Flows & Clarity
Flow: Varies by reach and releases; expect fluctuating but fishable winter flows in most sections.
Clarity: Generally clear to slightly stained in sections below urban tributaries — good visibility for nymphing.
Water Temperature
Current: Mid-to-high 30s°F (around freezing to ~3°C).
Trend: Cold and steady; fish are holding in deeper seams and slack water.
Weather Snapshot
This week: Cold with periodic sun; periods of light rain/sleet possible. Wind: light to moderate — dress in layers.
Access & Licenses
Most public access points are open but watch for ice near banks. Carry the appropriate state license for the section you fish (PA / NJ / NY). Check local municipal closures and private property signage.

Hatch Chart & Insect Activity

Insect Size Activity Level Where & When
Midges (larvae & pupae) #18–24 High All reaches; best late morning to warmest afternoon pockets
Baetis / BWO (light hatch spells) #18–22 Low–Moderate Warm, sheltered stretches on sunny days
Caddis (limited) #14–18 Light Evenings along slower tails and back eddies
Stoneflies (patchy) #8–14 Very Light Shallow riffles in upper tributary-fed stretches
Egg/Scud targets (trout focus) n/a (soft flies & blobs) Moderate Deep seams and tailouts where trout concentrate

Recommended Flies (links to order / reference)

Winter on the Delaware rewards a patient, subtle approach. Below are proven patterns (highly ranked selections) with links — match sizes to the insect table above and fish depth.

Dry Flies / Emergers

Nymphs & Jigs

Streamers & Pike/Predator Patterns

Midge / Egg / Micro Patterns (winter staples)

Tactics & Quick Rigging

Winter is a slow, precision game. Read fish location (deep seams, tails, slacks) and present low-and-slow.

Nymphing

  • Indicator or Euro (tight-line) rigs both work. Use tungsten jig nymphs to reach bottom quickly. Leaders: 9–11' 4X–6X for winter trout.
  • Strike detection: watch subtle pauses and weight changes — fish often inhale slowly in cold water.

Dry Fly / Emerger

  • When baetis or caddis activity shows, drift emerger patterns and smaller parachutes in seams and pocket water. Keep drifts drag-free.
  • Presentation wins: long, natural drifts near inside seams and behind small current breaks.

Streamers

  • Fish streamers on a short line with aggressive strips in cold spells (to provoke a reaction) or slow sweeps in clear, deep pools.
  • Use a 6–8 wt with a stout leader when swinging larger sculpin/baitfish imitations.

Where to Fish — By Reach

Upper Basin (Catskills / Hancock area)
Cleaner water, classic trout pockets. Best for tight nymphing and midges in January.
Middle River (Dingmans / Milford)
Mix of pocket water and deeper runs — good for streamer work and jigs near current seams.
Lower River (Trenton / Wilmington areas)
Wider, warmer stretches hold tailwater trout and predators — focus deeper structure and baitfish streamers.

Gear, Leaders & Tippet

  • Rods: 3–5 wt for finesse nymph/dry, 6–8 wt for streamers.
  • Lines: Floating for dries & nymphs (with long leaders) — switch to weight-forward sink tips for heavy streamers.
  • Leaders & tippet: 9–12' leaders, 4X–6X tippet for nymphs/drys; 2X–3X for streamers.
  • Use tungsten jigs and small perdigons to get to depth in winter flows.

Regulations, Safety & Conservation

The Delaware crosses multiple jurisdictions — ensure you carry the correct state license and follow possession/size limits for the stretch you fish. Winter bank conditions can be icy; wear traction devices and a floatation vest if wading deeper water. Practice careful handling: wet hands, quick photo, and revive trout before release.

Short-Term Forecast & Strategy

Over the next 7 days expect continued cold with intermittent cloud and sun. Fish the warmest, sheltered windows for surface activity; otherwise work mid-depth and bottom with jigs / tungsten nymphs. If a sunny afternoon appears, try a short dry/emerger session where baetis shows.
