New York Tailwater
Delaware River Fishing Report, Flows and Hatches
The East Branch below Pepacton Reservoir, a cold Catskill tailwater that joins the West Branch at Hancock. Wild browns, technical currents, and the same spring-into-summer dry fly fishing the Delaware system is known for.

How it fishes
A New York tailwater
A tailwater runs out of the bottom of a dam, so the water comes out cold and steady all year. That stable temperature is why the bugs stay small and the hatches run like clockwork, and it is why the fish grow picky and well fed. The flip side is that the dam sets the flow, not the weather, so a release can change the river overnight. You read the gauge, not the sky.
Flow and gauge
Reading the flows
The Delaware is metered at USGS gauge 01417500. Watch the trend as much as the number: a river that is dropping and clearing fishes very differently from one that is coming up.
Low
under 2,000 cfs
Optimal
2,000 to 6,000 cfs
High
above 8,000 cfs
Access and regulations
Before you fish
Access and the right to fish are the angler’s responsibility, every time. Public access, private water, and seasonal closures vary along the river, so confirm where you can legally stand and wade before you go. We do not point you to a specific spot.
Read the current rules, license requirements, and any special-regulation water before you go. Regulations change season to season, so check them fresh.
Flow and water temperature from USGS, weather from NWS and NOAA, refreshed hourly. Real-time USGS readings are provisional and subject to revision. The hatch chart and river read are Rivus model output.
