Information sur la source

The Salmon Drift Creek Watershed Council (SDCWC) has been collecting water samples since 2006. Water samples are collected by the Watershed Council with the help of volunteers. The Water Quality Program Manager oversees and coordinates the sampling and analysis along providing training to new volunteers. Samples are processed using the IDEXX system. The water at the sample sites are tested for E.coli (freshwater) or Enterococcus (ocean or estuary) as well as dissolved oxygen, temperature, pH, specific conductance, and turbidity. Water Quality Data are compared to state and federal standards as part of a baseline monitoring program. SDCWC does not issue any advisories, but information is available for public's use. The monitoring program is variable based on funding and resources. As results become available they are shared on Swim Guide. Monitoring Status: SDCWC follows Oregon’s standard for the monitoring of its recreational waters. This does not include such uses as shell fish harvesting and thus the results are not protective or to be used for gauging the safety of harvesting or commercial cultivation of clams or other species. That value is limited to 14 Fecal coliform bacteria per 100ml. E. coli A beach is marked GREEN when single sample results are less than 406 cfu per 100 mL and when applicable, a 90-day geometric mean is less than 126 cfu per 100 mL). A beach is marked RED when a single sample exceeds 406 or the 90 day geometric average exceeds 126. Enterococcus A beach is marked GREEN when a single sample is less than 130 organisms per 100 ml. A beach is marked RED when a single sample is greater than 130 organisms per 100ml. This level is set by the Beach Action Value established by Oregon Health Authority in 2017. A beach is marked Grey if there is no current results or no available information. SDCWC is currently supported by the Confederated Tribes of Siletz Indians, Oregon Watershed Enhancement Board, Oregon Department of Environmental Quality, Surfrider Blue Water Task Force, and Neighbors For Kids in Depoe Bay, Oregon where their bacteria lab resides.
