Water Quality Monitoringwater sampling

SDCWC conducts bi-weekly sampling and analysis of water quality in the Salmon River, Schooner Creek, Devils Lake, and Drift Creek basins. The parameters SDCWC monitors include temperature, conductivity, turbidity, pH, bacteria load, dissolved oxygen, and stream flow.

Salmon River and Thompson Creek have been listed under Section 303(d) of the Clean Water Act for temperature and dissolved oxygen impairment. SDCWC’s water quality data contributes to the Oregon Department of Environmental Quality’s effort to establish Total Maximum Daily Loads (TMDL) for these two streams.

TMDL is a calculation of the maximum amount of a pollutant that a waterbody can receive and still safely meet water quality standards (US Environmental Protection Agency). For more information about TMDLs and Section 303 (d) of the Clean Water Act, click here.

SDCWC's Water Quality Monitoring Program is funded by the Oregon Watershed Enhancement Board and Oregon Department of Environmental Quality, and supported by a team of very dedicated volunteers.
