Short Description

Between June and November 2000, the Washington State Department of Ecology (Ecology) measured flows and developed continuous stage records at three sites on the Little Klickitat River.

Monitoring was conducted in support of a Temperature Total Maximum Daily Load (TMDL) study developed by Ecology. The purpose of this TMDL was to characterize water temperature and to establish load and wasteload allocations for heat sources in order to meet water quality standards for surface water temperature in the basin.

Abstract Long Description

Between June and November 2000, the Washington State Department of Ecology (Ecology) measured flows and developed continuous stage records at three sites on the Little Klickitat River. The uppermost station was located west of Hwy 97 just north of Goldendale, the middle station was at the Olson Road crossing southwest of Goldendale, and the lower station was located alongside Hwy 142 (M.P. 19) approximately 1/4 mile above the confluence with the Klickitat River.

Monitoring was conducted in support of a Temperature Total Maximum Daily Load (TMDL) study developed by Ecology. The purpose of this TMDL was to characterize water temperature and to establish load and wasteload allocations for heat sources in order to meet water quality standards for surface water temperature in the basin.

Continuous stage height recorders and staff gages were installed, and four to six instantaneous discharge measurements were taken at all three sites. Discharge rating curves were developed for each site by relating various stage height values to their corresponding instantaneous discharge measurements. Doing so related the river stage to a corresponding instantaneous discharge measurement. These rating curves were then applied to the continuous records of each station to predict daily average discharge values. Measured discharge of the Little Klickitat River ranged from 3 cfs above the city of Goldendale to 58 cfs near the mouth. Predicted discharge values based on continuous records ranged from 1.5 cfs above Goldendale to 70 cfs near the mouth. The r2 values for regressions of discharge against transducer values ranged from 0.90 to 0.99. The lower r2 of 0.90 may be the result of vandalism at one of the stations
