Utah Tailwater
Green River Fishing Report, Flows and Hatches
A gin-clear tailwater carving through red rock canyon below Flaming Gorge Dam. One of the densest trout populations in the West, sight-fished on year-round midges until the June cicadas pull the big browns to the top.

How it fishes
A Utah 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 Green is metered at USGS gauge 09234500. Because a dam sets the flow, the number can change overnight with a release, so it is worth a look before you load the truck.
Low
under 800 cfs
Optimal
800 to 2,800 cfs
High
above 3,000 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.
