Irrigation pipe on the North Santiam river supplies water to local agriculture. 

These scientists are working on The Great Salt Lake to determine the amount of water and qualities of it. This will help them in developing better management techniques that will work to support the migratory birds that frequent the area. 

These brine flies are an important fuel source for migratory birds, giving them energy for long flights. 

An acoustic doppler current profiler or ADCP is pulled across the channel by a hydrologic technician using the yellow tagline. An ADCP uses sound waves to measure the speed of currents throughout the water column.

Scientists collect a routine water level depth measurement in the Klamath Falls basin-wide monitoring network.

Warner Lakes in Oregon photographed from the eastern ridge looking west. In 2022 the lakes were dry due to an extended drought in the western U.S.

A YSI Sontek M9 acoustic doppler current profiler (ADCP) measures the flow along the Sevenmile Canal. The Sevenmile Canal is a tributary to Upper Klamath Lake.

Two black stacked PVC pipes along Fall Creek house water-quality sensors. The bottom pipe has the sensors deployed at the site and the top is used to deploy reference sensors during site calibration and cleaning visits.
