PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2024 (ver. 4.0, August 2024)

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 transponder

Acoustic-tagged juvenile Chinook salmon (Oncorhynchus tshawytscha) detections in Lookout Point Reservoir and downstream in the Middle Fork Willamette River, Oregon

Federally-threatened ago-0 spring Chinook salmon (Oncorhynchus tshawytscha) were acoustic tagged and released near Lookout Point Reservoir to estimate passage and survival during 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 surface elevation of Lookout Poin

Data on the capture, tagging, and detection of White River Spinedace in the Flag Springs Complex, Nevada 2020-2022

Data were collected at the Flag Springs Complex on the Wayne E. Kirch Wildlife Management Area in Nevada to study the seasonal movements, habitat use, and survival of White River Spinedace. The dataset comprises information on PIT tagged White River Spinedace detected passively by remote antennas, along with habitat characteristics data. Length, weight, and species data were recorded during four b

Spring Viremia of Carp Virus (SVCV) Infection Trials of Pacific Northwest Amphibians.

Spring viremia of carp virus (SVCV) is a rhabdovirus that primarily infects cyprinid finfishes and causes a disease notifiable to the World Organization for Animal Health. Amphibians, which are sympatric with cyprinids in freshwater ecosystems, are considered non-permissive hosts of rhabdoviruses. The potential host range expansion of SVCV in an atypical host species was evaluated by testing the s

Evaluation of Lethal and Sublethal Effects of 6PPD-Q on Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii)

6PPD-Quinone (6PPD-Q) was recently implicated in inducing mass pre-spawn mortality events in adult coho salmon (Oncorhynchus kisutch) in the Pacific Northwest. Since then, studies have reported highly variable toxicity among fish species, including within the salmonids. This dataset explores the sensitivity of coastal cutthroat trout (Oncorhynchus clarkii clarkii) at three different life stages: a

Environmental DNA survey results for Oncorhynchus mykiss and Cottus aleuticus in coastal streams of Big Sur, California, 2021-2022

The data support a study that surveyed the spatial distribution of Oncorhynchus mykiss and Cottus aleuticus eDNA in coastal streams of Big Sur, California, 2021-2022 following post-fire debris flows. The metadata represent qPCR quantification cycle (Cq) values for O. mykiss and C. aleuticus assays performed on water samples collected during June and July of 2021 and 2022 from the following streams

PIT Tags Encountered by Klamath Falls Field Station Equipment in the Upper Klamath Basin 1993-2024 (ver. 3.0, April 2024)

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 transponder

Data collected in 2009-2012 to assess benthic macroinvertebrate response to dike removal on the Nisqually River delta

Macroinvertebrate and environmental data were collected annually in July-August in the year before dike removal (2009) and the first three years after dike removal (2010-2012) at the Nisqually River Delta, Washington, U.S.A. Data were collected along a gradient extending from the inner marsh edge to the delta front and spanning different types of habitat including marsh restored to tidal inundatio

Daily and annual abundances of natural- and hatchery-origin age-0 fall Chinook salmon (Oncorhynchus tshawytscha) passing Lower Granite Dam, Washington 1992 - 2021

The main contents of this data release are estimates of daily and annual abundances of federally-threatened natural-origin age-0 fall Chinook salmon (Oncorhynchus tshawytscha) passing Lower Granite Dam, Washington. Fish from this population are sampled as they pass Lower Granite Dam, but these sample data cannot be used directly to infer abundance because capture probability at Lower Granite Dam v

Upper Skagit Reservoir Food Web Data, 2005-2021

This release includes data used to evaluate the structure and function of the Ross Lake and Diablo Lake food webs. This includes data on zooplankton density and production (zooplankton_density.csv and daphnia_region_production_biomass.csv), lake volume estimates used to expand zooplankton density and production data (lake_volume_estimates.csv), fish sampling (FishSampleEvents.csv), fish biological

Upper Skagit River intrinsic potential results

We assessed habitat suitability for salmonids across selected tributaries upstream from three hydroelectric dams on the upper Skagit River in Whatcom County, northern Washington. We used NetMap, a commercial toolset within the ArcMap geographic information system (GIS), to analyze stream attributes based upon a synthetic stream channel network derived from digital elevation models. The GIS-derived

Upper Klamath Lake and Clear Lake sampling for suckers from 2015 through 2022

Data in this data set include effort expended to collect suckers for cohort tracking and metrics and observations for each sucker captured from 2015 through 2022. There are two levels of data. All Nets data contains 5102 records and the data file is 609 KB. Captures data contains 3764 records and the data file is 504 KB. The data files can be linked by setID which is a unique identifier for a uniq
