Lake Spokane Nutrient Monitoring, 2010-2011: Data Summary Report

In June 2013, Ecology released the “Lake Spokane Nutrient Monitoring, 2010-2011: Data Summary Report”

Ecology describes the report as follows:

“The last major monitoring effort on Lake Spokane occurred in 2001 during TMDL development. As the TMDL moves from development to implementation, more up-to-date data are needed to verify the baseline condition of Lake Spokane. These data will be used for comparison with future effectiveness monitoring data. They also may be used for additional verification of the CE-QUAL-W2 model that was used during TMDL development.

Regular critical-period sampling on Lake Spokane, the Spokane River, and the Little Spokane River began in 2010. Sampling was conducted by the Department of Ecology and Avista Corp. Parameters sampled are pH, temperature, conductivity, dissolved oxygen, alkalinity, ammonia nitrogen, chlorides, chlorophyll-a, total and dissolved organic carbon, nitrate and nitrite nitrogen, ortho-phosphorus, total dissolved solids, total persulfate nitrogen, and total phosphorus.

This data summary report covers sampling conducted May-October 2010 and May-October 2011.”
