Columbia River Research Laboratory (CRRL)

The Columbia River Research Laboratory was established in 1978, tracing its roots to the previous Reservoir Program of the Fish and Wildlife Service, in the Columbia River Gorge east of Portland. The CRRL, the Center’s largest field station, carries out research throughout the American West, including Puget Sound, the Columbia River Basin, the Klamath River Basin, and the Sacramento Bay Delta.

Spatial and temporal overlap between hatchery- and natural-origin steelhead and Chinook salmon during spawning in the Klickitat River, Washington, USA

A goal of many segregated salmonid hatchery programs is to minimize potential interbreeding between hatchery- and natural-origin fish. To assess this on the Klickitat River, Washington, USA, we used radiotelemetry during 2009–2014 to evaluate spatiotemporal spawning overlap between hatchery-origin and natural-origin steelhead Oncorhynchus mykiss and spring Chinook Salmon O. tshawytscha. We estimat

Movement and behavioral states of common carp (Cyprinus carpio) in response to a behavioral deterrent in a navigational lock

Freshwater ecosystems are some of the most affected by biological invasions due, in part, to the introduction of invasive carp worldwide. Where carp have become established, management programs often seek to limit further range expansion into new areas by reducing their movement through interconnected rivers and waterways. Lock and dams are important locations for non-physical deterrents, such as

Behavior and movement of smallmouth bass (Micropterus dolomieu) near Bonneville Dam, Columbia River, Washington and Oregon, March–October 2022

A telemetry study was conducted during March–October 2022 to evaluate behavior and movement patterns of adult smallmouth bass (Micropterus dolomieu) in the forebay of Bonneville Dam, on the Columbia River in Washington and Oregon. This study was a follow-up to a previous study conducted at the site during August–December 2020. In 2022, a total of 41 smallmouth bass were collected, tagged, and rele

Southwestern Willow Flycatcher Habitat Viewer

For planning and management purposes, agencies require a web application that can locate, map, and monitor Southwestern Willow Flycatcher (flycatcher) breeding habitat across its range. The Habitat Viewer can identify potential flycatcher habitat and monitor changes caused by stressors, such as beetles, fire or drought.
