Correlative estimates of discharge for three sites in the upper Lewis River Basin, Washington

Abstract

In response to increased interest in the power possibilities of tributary streams in the headwater of Lewis River stream-gaging stations were reestablished in 1955 at three sites in the upper Lewis River basin, Washington. The one year of recent record now available and the four years of record obtained during water years 1928-31 provide a reasonable basis for estimates of monthly discharge during the intervening years. In view of the current interest in the discharge of these streams estimates of monthly discharge have been made in the Tacoma district office of the Surface Water Branch of the U.S. Geological Survey. These estimates and a description of the method of correlation are attached. The three stations and the period covered by the correlative estimates are as follows: Big Creek below Skookum Meadow near Trout Lake, Washington: Oct. 1931 to Sept. 1955 Meadow Creek below Lone Butte Meadow near Trout Lake, Washington: Oct. to Dec. 1928; Oct. 1931 to Sept. 1955 Rush Creek above falls, near Cougar, Wash.: Oct. to Dec. 1928; Dec. 1931 to Sept. 1955 Published records for water years 1928-31 and 1956 are included in the tabulation to provide discharge for the full period Oct. 1927 to Sept. 1956.
