Ambient Water Quality Data
Click on a specific watershed and drill down through the links to view parameters of interest:
The Washington State Department of Ecology has conducted monthly water quality monitoring at hundreds of stream stations throughout the state for nearly 50 years. Ecology routinely measures indicators of water quality such as ammonia, nitrate/nitrite, phosphorus (total and soluble reactive), conductivity, nitrogen, suspended solids, fecal coliform bacteria, oxygen, temperature, flow, pH, turbidity, and metals.
The Environmental Information Management (EIM) Database
This data base provides access to over 12.5 million environmental records on air, water, soil, sediment, aquatic animals and plants. To locate information relating to Avista’s activities at Lake Spokane, search the EIM Database for Lake Spokane as the subject.
Spokane River and Lake Spokane (Long Lake) Pollutant Loading Assessment for Protecting Dissolved Oxygen (Cusimano, 2004)
The report summarizes the predicted water quality conditions in the Spokane River system under different loading conditions using the hydrodynamic and water quality computer model CEQUALW2 developed for the project. In addition, the report provides an assessment of the historical water quality data for the river system and existing phosphorus TMDL for Lake Spokane. Author: Bob Cusimano
