Operating a cable car
Measuring streamflow from a human powered cable car takes a lot of skill and quick thinking. A flow meter is lowered into the water using a reel.

Gage house maintenance
Sometimes climbing up on top of a gage house is necessary to check on the condition of the solar panel and satellite antenna.

Measuring Middle Fork Coquille river
Esteemed Hydrologic Technician, Katie Baker, measures streamflow with an acoustic doppler current profiler (ADCP). The ADCP tracks the velocity of particles in the water and maps the channel bottom, combine that data with channel width and you can calculate stream flow!

Elevation levels at Fall Creek Reservoir
One of our incredible hydrologic technicians is in full safety gear, including fall protection and life vest, as she surveys elevation levels. In this photo the white level marker rod has fallen onto the pile of floating logs. It was safely retrieved!

Measuring wells in Klamath County
Hydrologic technicians use electronic tapes to measure groundwater in wells. The tape beeps or lights up when makes contact with water.

Cat inspects well depth measurement equipment
An electronic measuring tape will beep when it hits the surface of the water. This well inspection caught the attention of a neighborhood cat.

AA meter set up in cable car
Essential gear for measuring streamflow above large rivers. Within this cable car a reel connects to a Price AA flowmeter and sounding weight. Hydrologic technicians reel down the weight until they hit the river bottom, input the total depth into the AquaCalc, then they measure the flow within the water column at various depths to best capture water velocities.

Sediment sampler at Breitenbush River
Sediment samplers are designed to obtain representative samples across all depths and locations in a river cross-section. This is important because sediment concentrations are not always consistent across the channel. This D-74 sampler weighs 62 pounds and can sample in velocities up to 6.6 feet per second and depths up to 15 feet. It has been in use since 1974.

Fall Creek meets the Middle Willamette River flows
A striking contrast between the clear water in the Middle Fork Willamette River and brown water in Fall Creek. The flows from Fall Creek dam during this time had heavy loads of suspended sediment from the reservoir drawdown.

Substrate mapping on Little North Santiam
River bed-sediment size and distribution is critical for fish spawning habitat. The kayaking scientist in this photo is towing an advanced acoustic instrument that measures river velocity and depth. In addition, a camera captures photos that can be used to create digital elevation models and eventually maps of river bed-sediment size.
