Statistical summaries of streamflow data for selected gaging stations in Idaho and adjacent states through September 1990 - Volume 1: Gaging stations with 10 or more years of record

This volume presents statistical summaries of streamflow data for 257 gaging stations with 10 or more years of continuous record through September 1990. The gaging stations are located in Idaho and adjacent States. Volume 2 presents statistical summaries of streamflow data for 76 gaging stations with 5 to 9 years of continuous record, or with records of discharge measurements from springs, through September 1990. The gaging stations are located in Idaho and western Wyoming.

Streamflow statistics generated for gaging stations with 10 or more years of record were (1) magnitudes of monthly and annual flows; (2) magnitudes and frequencies of daily low, high, instantaneous peak (flood frequency), and annual mean flows; (3) duration of daily mean flows; and (4) maximum, median, and minimum daily mean flows. Streamflow statistics generated for gaging stations with 5 to 9 years of record or that measure discharge from springs (volume 2) were (1) magnitudes of monthly and annual flows; (2) duration of daily mean flows; and (3) maximum, median, and minimum daily mean flows.
