What the water’s
telling us today.

Daily conditions, hatches, and technique — synthesized from across the watershed and written the way we’d tell a friend before they drove up.

Upper Delaware System
More Rivers — Coming Soon
Confirmed this morning
Bottom Line

Fish early or fish smart — the tailwaters are working, but the trout have earned their education this week.

River Outlook

Summer’s settled in hard across the system, and the story right now is really two stories — freestones versus tailwaters. Cool overnight temps have kept the Beaverkill and Willowemoc briefly fishable in the early morning for nymphing, but the smart money is on the tailwaters for anything past midday.

The West Branch remains the most consistent bet, though algae on the upper river has pushed some anglers toward dry-fly-only water and made nymphing there a lower-river game for now. Pressure is a real factor this week — sulphur hatches have been drawing crowds, and the fish have wised up accordingly. Expect technical refusals more often than easy eats.

What’s Hatching

Sulphurs and Blue Winged Olives are the midday headliners on the upper West Branch, with Isonychia nymphs active system-wide. Tan caddis, Light Cahill, and rusty spinners round out the box. The East Branch and upper Neversink are turning on mainly after dark.

Today’s Watch Items

  • Water temps climbing on the freestones
  • Algae limiting clean water on the upper West Branch
  • Heavy midday angler traffic on known sulphur water

Best Techniques

Morning belongs to the nymph anglers — swing or drift while you wait for the surface activity to build. Once hatches get going, it’s worth scouting for risers rather than blind-casting; fish under heavy pressure this week have been selective, so cripples, emergers, and a lighter tippet than usual will out-fish a standard dun imitation.

Worth trying: a small Sulphur dropped off the back of a dry Isonychia — bigger fly up top for visibility, small Sulphur trailing behind for the fish keying on the smaller bug. Let the drift swing at the end rather than picking it up right away — the Sulphur rises through the water column just like a natural emerger would, and that lift can draw a take on its own.

Fly of the Week

The Sulphur

Ephemerella dorothea · Sizes 16–20

Pale yellow, honest profile.

The bug everyone’s watching for right now. A pale yellow body with pale grey wings, riding low in the film — the trick this week isn’t finding it, it’s fooling fish that have already seen a dozen versions of it.

Technique tip: once pressure builds, drop to a cripple or low-riding emerger before you reach for a fresh dun pattern.

Jul 25 Sulphur pressure builds on the West Branch — same pattern, fish getting harder to fool.
Jul 19 Storm-driven color on the West Branch nudged fishing in a good direction before hatches resumed.
Jul 16 Smoke haze, warm afternoons — algae already limiting the upper river to dry-fly water.
