Data

Federally-threatened ago-0 spring Chinook salmon (Oncorhynchus tshawytscha) were acoustic tagged and released near Lookout Point Reservoir to estimate passage and survival during the second year of an experimental reservoir drawdown operation that was designed to facilitate downstream passage through two reservoirs and dams. The experimental operation consisted of lowering the water...

Data were collected as part of a long-term capture-recapture program to assess the population dynamics of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning...

Viral nervous necrosis is a neurologic disease that causes vacuolating lesions in the brain and retina of a broad range of marine fish species. The viral agent responsible is nervous necrosis virus (NNV), a Betanodavirus within the family Nodaviridae. Based on genetic characterization of the viral genome, at least four species of NNV are known to exist, though this diversity is likely...

Juvenile Chinook salmon (age 0 and age 1), steelhead, and sockeye salmon were tagged with acoustic transmitters and released at sites along the Yakima River in and below Yakima, WA from 2018 to 2024. Detection sites varied across years but included arrays placed at diversion dams, canals, hydropower facilities, and other locations throughout the Yakima and Columbia rivers. Study design...

These data were generated from a five-day laboratory study that compared environmental DNA (eDNA) concentrations derived from live and dead rainbow trout (Oncorhychus mykiss) to investigate how eDNA shedding differs between live and dead fish. Live and dead fish were each housed in separate tanks and eDNA samples were collected from each tank after 1, 2, 3, and 5 days. Additionally...

A study was conducted in the Yakima River Basin in Washington state to evaluate behavior of juvenile Chinook salmon and Coho salmon upstream of Tieton Dam from April to November 2024. The goal of this study was to collect data useful for designing and siting downstream fish passage options at the dam. Under current operations, water is passed through the dam via a deep intake located on...

Data were collected as part of a long-term capture-recapture program to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon and Clear Lake Reservoir, California. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated...

This geospatial dataset describes the location and spatial coordinates of each site where invasive African clawed frogs Xenopus laevis were detected in western Washington state between 2015 - 2023.

Data were collected as part of a long-term capture-recapture program to assess the population dynamics of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (LRS; Deltistes luxatus) and shortnose suckers (SNS; Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their spawning...

Passive integrated transponder (PIT) detections across the Upper Klamath River Basin were combined from all fish that were detected making a passage attempt at the Link River Dam fish ladder from 2008 - 2024. In July 2007, four PIT tag antennas (FS1001 Muliplexer transceiver [MUX] units) arrays which were originally installed by Biomark. In October 2023, antennas were upgraded to Biomark...
