Recent rainfall can influence river flow, but the timing and magnitude depend on watershed size, soil conditions, upstream reservoirs, and dam releases.

Fishery overview
The Green below Fontenelle is the Weeping Rocks tailwater at the USGS cable crossing. StrikeTracks publishes Monitoring-Backed conditions from USGS 09211200 (live discharge, stage, and water temperature). Distinct from Warren Bridge, the town of Green River, 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 Hatch Match remains unpublished for this identity after Option-B local-expert seasonal research. Fewer than two Fontenelle/Seedskadee independent seasonal charts.
