My Mountain Data

Sierra river flows & water levels

Check USGS and NOAA flow, gauge height, and water temperature where measured. Each reading identifies its exact station and observation time.

River gauges

Flow and gauge height apply to the exact monitoring station, not every reach of a river. Missing sensors are shown as not measured. USGS measurements are provisional.

Read a gauge in context

Discharge is reported in cubic feet per second (cfs); gauge height is the water level at that station, not a universal depth or a direct safety rating. Values describe the sensor location and can change with releases, weather, and local tributaries. Compare the observation time as well as the value, and follow the linked agency page for provisional-data notes.

Owens River sections

The Bishop gauge does not represent every Owens River reach. For additional sections and reservoir releases, use LADWP aqueduct conditions reports.
