Close to the WY/UT border just SW of Evanston, WY, Rees Creek is an upper tributary of the Weber River that has been identified as a major source of sediment in the river. The stream is intermittent and the CR10X data logger is programmed to measure water level. When water is detected, the data logger measures conductivity and turbidity and initiated a sample using a American Sigma sampler. Sensors are: FTS DTS-12 turbidity sensor, OTT Nimbus bubbler, and a Campbell Scientific conductivity and temperature sensor. The sensors are installed at the entrance of a 12 in. Parshall flume. This allows calculation of discharge from the stage (water level) reading. Power is from a deep cycle marine battery that is charged by a 20 Watt solar panel.
