Owyhee above Owyhee Snow Survey Summary
The NRCS Snow Survey monitors hydro-climatic conditions in the Owyhee above Owyhee sub-basin and uses these data to issue streamflow forecasts for the Owyhee River near Gold Creek to assist with management of Wildhorse Reservoir. There are seven SNOTEL data collection sites that monitor snowpack (snow water and snow depth), precipitation, soil moisture, and air temperature. Four sites are long-term sites installed between 1978-1980. The long-term sites have normals based on the 1991-2020 period which allows data to be presented as a percent of median. The other three sites have a short period of record and do not have enough years of data to generate daily normals and no percentage is reported. Below are various charts and reports that may be of interest.

Interactive SNOTEL Charts:
'Allow users to compare this year's data to any historical year(s). Graphs include statistical background data, such as the daily maximum, normal, and minimum, as well as shading based on the 10th, 30th, 50th, 70th, and 90th percentiles.
Streamflow Forecast Charts
This chart allows visualization of current and previous year forecasts compared to historic observed data, as well as, maximum and minimums. The NRCS adjusts Owyhee River near Gold Creek observed streamflow data for reservoir storage changes. The adjusted data is used to develop streamflow forecasts.
Historic Streamflow Data
Monthly streamflow data for the Owyhee River near Gold Creek is available as a chart or table. NRCS monthly streamflow data are adjusted for reservoir storage changes. The adjusted data is used to develop streamflow forecasts.
