Abstract

Streamflow statistics consisting of low flows, high flows, mean monthly flows, mean annual flows, flow durations, and peak flows were estimated for 16 sites on small streams on the Puyallup Indian Reservation, Washington. Drainage areas ranged from 0.62 to 16.7 sq mi. Streamflow statistics were also computed for the Puyallup River at Puyallup (gaging station 12101500). All of the small-stream statistics except for the peak flows were estimated by using station regression equations to transfer streamflow statistics for long-term gaging stations to the small-stream sites. An equation for each small-stream site was developed by regressing approximately 12 monthly measurements of discharge at that site with respect to concurrent daily mean discharges at a long-term gaging station. The coefficients of correlation between the discharges range from 0.98 to 0.79 except for one value of 0.58. Peak flows for the small-stream sites were estimated by use of regional regression equations. The regional regression equations, which express the statistics as functions of drainage area and mean annual precipitation, were developed using data for 26 gaging stations in the Puget Sound area.
