Fishery overview
The Green at Warren Bridge is the Upper Green fly-fishing destination at US 191. StrikeTracks publishes Monitoring-Backed conditions from USGS 09188500 (live discharge and stage; no qualifying current 00010, so thermal context uses the accepted air-derived river-trout path). Distinct from Fontenelle and Utah Flaming Gorge. Colorado River cutthroat, where WGFD-managed in the Green drainage, are not a StrikeTracks species-selector ID. Flow Context remains default-deny. Mountain whitefish (Prosopium williamsoni) are a native game fish in this drainage per official state fishery management; they are described here because StrikeTracks has no species-selector ID. Confirm current WGFD whitefish rules separately (https://wgfd.wyo.gov/fishing-hunting/fishing). Hatch Match remains unpublished for this identity after Option-B local-expert seasonal research. Single qualified seasonal source for Warren Bridge.
