RiverPro in the Snow near Klamath River at Keno, OR
RiverPro in the Snow near Klamath River at Keno, ORA RiverPro acoustic doppler current profiler (ADCP) is propped in the snow near the Klamath River in Keno, Oregon. The ADCP is used to measure streamflow.

Water collected from the lake at the bottom of Halema‘uma‘u
Water collected from the lake at the bottom of Halema‘uma‘uWater collected from the lake at the bottom of Halema‘uma‘u is prepared for laboratory analyses at the USGS California Volcano Observatory. Results thus far reveal chemistry indicative of complex reactions among the water, magmatic gases and Kīlauea's basaltic rocks.

Unoccupied Aircraft System is inspected by pilot just before take off
Unoccupied Aircraft System is inspected by pilot just before take offThe sampling mechanism (on blue tarp) is prepared and the Unoccupied Aircraft System (UAS) is inspected just before take off to collect water from the Halema‘uma‘u crater lake. Brightly colored flagging tape tied to a cable attached to the UAS indicated depth as the sampling tool was lowered into the water.

Study Map of Tagged Juvenile Late-Fall Run Chinook Salmon Released Upstream of Shasta Reservoir, California
Study Map of Tagged Juvenile Late-Fall Run Chinook Salmon Released Upstream of Shasta Reservoir, CaliforniaStakeholder interests have spurred the reintroduction of the critically endangered populations of Chinook Salmon to tributaries upstream of Shasta Dam, in northern California. We released two groups of acoustically tagged, juvenile hatchery, late-fall Chinook Salmon to determine how juvenile salmon would distribute and survive.

Looking downstream onto Hells Canyon Reservoir
The Snake River is the largest tributary of the Columbia River. It drains over 108,000 square miles in mainly Idaho and portions of Montana, Nevada, Oregon, Washington, and Wyoming. The climate of much of the Snake River watershed is arid or semi-arid and spring snowmelt contributes substantially to the river’s flow.
