Short Description

The Washington State Department of Ecology collected monthly water quality information at 84 river and stream monitoring stations during Wateryear (WY) 1995 (October 1, 1994, through September 30, 1995). The primary goals of this ongoing monitoring program are to characterize the rivers and streams of Washington State and to track changes in water quality. Water quality for WY 1995 was average relative to previous years.

Abstract

Long Description

The fecal coliform bacteria geometric mean was the most frequently violated criterion based on individual samples. The geometric mean criterion was exceeded 154 times, and 99 samples exceeded the "10 percent not to exceed" criterion out of about 1000 samples collected. Forty-seven of 84 stations had at least one sample that exceeded the geometric mean criterion. Twenty-eight stations were west of the Cascades of which 14 were stations on streams that drain to Puget Sound. Temperature standards were violated 65 times at 37 stations on both sides of the Cascades. Dissolved oxygen and pH standards were violated 46 and 28 times, respectively, at 20 and 15 stations. With a few exceptions, median monthly stream flows in WY 1995 at the time of sampling were normal.
