Monitoring Sediment and Turbidity in Clear Creek

Science Center Objects

To help protect critical salmonid spawning habitat, we are monitoring streamflow, water temperature, turbidity, and suspended sediment concentrations on Clear Creek upstream of the confluence with the Middle Fork Clearwater River. We are conducting this monitoring in cooperation with the Nez Perce Tribe.

The objectives of the study are to:

  • Quantify the suspended sediment and turbidity concentrations and suspended sediment loads at the streamgaging station for three¬†years.
  • Evaluate the relationship between turbidity and suspended sediment concentration and construct sediment and turbidity rating curves.
  • Collect real-time stream temperature data at the streamgaging station.
  • Publish real-time streamflow, water temperature, turbidity, and suspended sediment concentrations and loads via the USGS National Water Information System website.
  • Establish long-term monitoring of water temperature, turbidity, sediment, and streamflow to identify trends associated with these parameters.
