Is there a flow forecast for Bear River near Utah-Wyoming State Line?
Yes. Rivermatics trains a machine-learned model — a temporal-fusion transformer — on this basin's observed flows, weather, and snowpack, and issues a daily flow outlook reaching 14 days ahead: a median estimate inside a confidence band, not a single number to bet on. Every forecast is scored against days the model never trained on, and that track record is published on the live gauge screen. Open live conditions to see the current outlook.
Where is Bear River near Utah-Wyoming State Line?
The gauge sits at 40.96521, -110.85354, in Utah, in hydrologic subbasin 16010101, at an elevation of about 7,961 feet, draining roughly 172 square miles.
