Wyoming Freestone
Green River Fishing Report, Flows and Hatches
The upper Green above Fontenelle, a high Wyoming freestone that blows out through May and June and comes into shape in July. The gray drake that covers Pinedale in midsummer is the hatch people plan around, not the year-round midges of the tailwater Green far downstream.

How it fishes
A Wyoming freestone
A freestone river runs free off snowmelt and rain, so it swings hard with the seasons. It blows out and browns up in spring runoff, then drops and warms into summer. The hatches track the water temperature more than the calendar, so you time your trip to the flow and the thermometer.
Flow and gauge
Reading the flows
The Green is metered at USGS gauge 09188500. Watch the trend as much as the number: a river that is dropping and clearing fishes very differently from one that is coming up.
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.
