Streamflow characteristics of the Green, Bear, and Snake River basins, Wyoming, through 1984

A summary of streamflow characteristics as of 1984 is presented for the Green, Bear, and Snake River Basins in Wyoming and adjacent areas, based on data from 101 streamflow-gaging stations. Streamflow characteristics include mean monthly and mean annual streamflow, duration of daily mean flow, and magnitude and probability of instantaneous peak flow, annual high flow, and annual low flow. Recurrence intervals of 2, 5, 10 , 25, 50 and 100 yr are utilized for the peak-flow, high-flow and low-flow characteristics. Low-flow and high-flow characteristics are also listed for standard periods of consecutive days. A station description, tables of streamflow characteristics, and graphs of mean monthly streamflow and duration of daily mean streamflow are presented for each station. Streamflow characteristics before and after dam construction are presented for five stations. (USGS)
