This is a landscape photo of the Klamath River with mountains on either side of the photo. The Western Fisheries Research Center is researching the effects of flow management before and after dam removal on juvenile Chinook salmon survival to the ocean. 

Map of the Northwestern United States showing major volcanic features associated with the mantle plume currently underneath Yellowstone caldera.  Colors indicate general basaltic (blues) versus rhyolitic (reds) compositions, with shades indicating age (darker shades are older).  Rough outlines of calderas that formed due to the Yellowstone hotspot are give

Temperature logger attached to submerged cobble in Quartzville Creek, OR. This logger was placed as part of an ongoing effort to retrieve continuous temperature data from rivers and tributaries within the Willamette River basin, OR.

This map shows 2024 shrub cover from the Rangeland Condition Monitoring Assessment and Projection (RCMAP) project across the McDermitt Caldera, outlined in gray, along the Nevada–Oregon border. Dark green areas indicate high shrub cover, typically found in riparian zones and at higher elevations.

A young rough-skinned newt in a defensive posture known as "unkenreflex." Several amphibian species curl up their bodies to display their brightly colored bellies as a warning to predators that they are poisonous.

This map, taken from a 2024 journal article by Furlong et al. 2024, shows the location and magnitude of seismic events (earthquakes) and rock type on a basemap of a portion of the west coast of North America.

Map of Newberry volcano shows location where earthquakes occurred during geothermal work in 2012 and 2014 (orange circles) and volcanic earthquakes that have occurred since 2011 (blue circles).

This is Keno Dam, in Klamath, OR. The Western Fisheries Research Center (WFRC) is doing work here to ensure proper fish passage is functioning and to provide science to help better address the water needs of the Klamath River Basin.

The Western Fisheries Research Center (WFRC) is partnering with the U.S. Bureau of Reclamation to discuss ways to monitor fish passage at Keno Dam. With the recent removal of four mainstem dams along the Klamath River, Keno Dam now stands as the most downstream fish passage challenge , and the first major obstacle for migrating salmon returning upstream.

This geomorphic map of Echo, Oregon shows the town is built on valley bottom terrain. Other landforms such as slopes, fans, bedrock, etc. are delineated in the surrounding area. From https://www.usgs.gov/maps/geomorphic-map-umatilla-river-corridor-oregon.

Underside of Bell Jet Helicopter with thermal infrared and true-color image sensors and JN and M.D. The helicopter is used for airborne surveys of river reaches to capture temperature values of water-surfaces.

A tall, partially dead western juniper (Juniperus occidentalis) surrounded by smaller, dead juniper trees. Project ROAM (Rapid and Other Methods for Assessment and Monitoring) plots are sampled across a variety of rangeland ecosystems and treatment prescriptions, including juniper removal.

Fish health monitoring efforts in Upper Klamath Lake have revealed a high prevalence of warmwater pathogens. The fish health team is investigating parasites as a potential threat to the vulnerable sucker populations.

This is a photo of a sunset in August, 2024 in Klamath Falls, OR. The Western Fisheries Research Center (WFRC) conducts work on fish health and monitoring in this area.

Profile view of a Bell Jet Helicopter with a thermal infrared and true-color sensor co-mounted to the underside of the nose. These sensors are used in airborne thermal infrared surveys for remotely sensing land/water surface temperature.
