Coho salmon migrating on the Sol Duc River, Washington to spawning grounds upstream. Fish must leap through a series of small waterfalls called the Salmon Cascades in Olympic National Park to reach the waters where they were born to complete their life cycle by spawning the next generation.

A sediment sample collection bag and jar sit on soils burned in the 2021 Muckamuck wildfire. Scientists are studying the sediment and water quality in rivers and reservoirs impacted by the large fire. The high temperatures of severe wildfires are capable of releasing and redepositing metals on the soil surface.

An illustration of a mountain with water flowing from the top down to a river with smaller rivers flowing off the sides. Multiple items appear along the various rivers including leaky weirs, one rock dams, log dams, gabions, check dams, trincheras, and earthen berms. Informational bubbles appear alongside these various item in the illustration.

Brian Ekstrom and Lance Downing of USGS are pulling a beach seine to collect juvenile fish for monitoring at a restoration site on the lower Columbia River. The restoration site was created with dredge material in October of 2020 and USGS is monitoring juvenile salmon use, community assemblage, and predator presence.

Sampling drifting invertebrates from a stream in the North Cascades of Washington State. We perform drift sampling to determine the invertebrate prey quality and quantity available for drift feeding fish. Data gathered from this sampling are used in bioenergetics modeling, a method of estimating fish growth potential.

Close-up oblique views of Mount Rainier’s west side showing simulated lahar flow depths from a landslide originating in the area of the Tahoma Glacier Headwall (T-260-HM simulation). Imagery appears blurry where lahar material is absent because D-Claw’s adaptive mesh refinement (AMR) employs very coarse resolution in those areas.
