  • UPDATE, 11/9: As of November 8, the USGS has successfully restored all of the operational gages that stopped transmitting due to an issue with the satellite telemetry system that records and transmits data. The USGS will now focus on restoring other equipment that experienced the telemetry issues, including about 85 rapid deployment gages that are used periodically for emergency response. Read more

Station Notes
This station has two turbidity sensors that use different methods for measuring turbidity. Turbidity values from these sensors are not directly comparable and it is common for the sensors to produce different readings. Due to extreme sediment conditions in the Elwha River, reported DTS-12 values above 1,000 FNU may be subject to reduced accuracy. For turbidity conditions greater than 1,000 FNU, refer to available data from the Analite sensor.

On January 27, 2017, Turbidity, water, unfiltered, monochrome near infra-red LED light source, 780-900 nm, detection angle 0-45 degrees to incident light (backscatter), FBU, [ANA] records were revised for Sept. 18, 2013 to Sept. 30, 2014. (Message posted January 30, 2017)
