Description The Department of Ecology collected monthly water quality data at 88 stream monitoring stations during Water Year 2012 (October 1, 2011 - September 30, 2012). We also collected 30-minute interval temperature data at 38 sites year-round for eight stations. The rest were measured from July through September 2012.

The principal goals of this ongoing monitoring program are to monitor trends in water quality of rivers and streams in Washington State, support a probabilistic monitoring program, and support Clean Water Act Section 303(d) reporting.

This year’s annual report includes a quality control analysis of (1) continuously monitored data using multi-parameter (oxygen, temperature, pH, and conductivity) instruments and (2) total phosphorus data collected from lakes monitoring for aquatic plants.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
