Statistical Summaries Of Streamflow Data For Selected Gaging Stations In Idaho And Western Wyoming Through September 1990 PDF Download

Statistical summaries and graphs of streamflow data were prepared for 13 gaging stations with 5 or more years of continuous record on and near the Idaho National Engineering Laboratory. Statistical summaries of streamflow data for the Big and Little Lost Rivers and Birch Creek were analyzed as a requisite for a comprehensive evaluation of the potential for flooding of facilities at the Idaho National Engineering Laboratory. The type of statistical analyses performed depended on the length of streamflow record for a gaging station. Streamflow statistics generated for stations with 5 to 9 years of record were: Magnitudes of monthly and annual flows; duration of daily mean flows; and maximum, median, and minimum daily mean flows. Streamflow statistics generated for stations with 10 or more years of record were: Magnitudes of monthly and annual flows; magnitudes and frequencies of daily low, high, instantaneous peak (flood frequency), and annual mean flows; duration of daily mean flows; exceedance probabilities of annual low, high, instantaneous peak, and mean annual flows; maximum, median, and minimum daily mean flows; and annual mean and mean annual flows.
