Patterns, drivers, and a predictive model of dam removal cost in the United States Patterns, drivers, and a predictive model of dam removal cost in the United States
Given the burgeoning dam removal movement and the large number of dams approaching obsolescence in the United States, cost estimating data and tools are needed for dam removal prioritization, planning, and execution. We used the list of removed dams compiled by American Rivers to search for publicly available reported costs for dam removal projects. Total cost information could include...

Tire-derived transformation product 6PPD-quinone induces mortality and transcriptionally disrupts vascular permeability pathways in developing coho salmon Tire-derived transformation product 6PPD-quinone induces mortality and transcriptionally disrupts vascular permeability pathways in developing coho salmon
Urban stormwater runoff frequently contains the car tire transformation product 6PPD-quinone, which is highly toxic to juvenile and adult coho salmon (Onchorychus kisutch). However, it is currently unclear if embryonic stages are impacted. We addressed this by exposing developing coho salmon embryos starting at the eyed stage to three concentrations of 6PPD-quinone twice weekly until...

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

Development of a quantitative PCR assay for detecting northwest salamander (ambystoma gracile) in environmental DNA samples Development of a quantitative PCR assay for detecting northwest salamander (ambystoma gracile) in environmental DNA samples
We developed a primer and probe based quantitative PCR assay for use with environmental DNA to detect Northwest salamander (Ambystoma gracile), a species endemic to the temperate Pacific coastal region of North America. The assay targets a region in the mitochondrial DNA (mtDNA) D-loop gene. Tests of the assay were performed in silico (using the NCBI BLAST tool), in vitro (using DNA...

Synthesis of larval lamprey responses to dewatering: State of the science, critical uncertainties, and management implications Synthesis of larval lamprey responses to dewatering: State of the science, critical uncertainties, and management implications
Objective Dewatering of fine sediments in rivers and streams can kill many thousands of larval lampreys (order Petromyzontiformes) that are burrowed in these habitats. The larval life stage for lampreys lasts 3–10 years, and because larvae often aggregate in large numbers, negative impacts from dewatering could potentially deplete local populations and affect multiple year-classes...

Calibration of the Trinity River Stream Salmonid Simulator (S3) with extension to the Klamath River, California, 2006–17 Calibration of the Trinity River Stream Salmonid Simulator (S3) with extension to the Klamath River, California, 2006–17
The Trinity River is managed in two sections: (1) the upper 64-kilometer (km) “restoration reach” downstream from Lewiston Dam and (2) the 120-km lower Trinity River downstream from the restoration reach. The Stream Salmonid Simulator (S3) has been previously constructed and calibrated for the restoration reach. In this report, we extended and parameterized S3 for the 120-km section of...

A decision-support framework for dam removal planning and its application in northern California A decision-support framework for dam removal planning and its application in northern California
Dam removals are occurring more frequently with the rising cost of maintaining aging infrastructure, public safety concerns, and growing interest in river restoration. So far, most dam-removals have been unsystematic in their approach. Given the several thousand dam removals expected over the coming decades, a systematic approach to plan future dam removals holds potential for aligning...

Broadscale distribution, abundance and habitat associations of the invasive Asian clam (Corbicula fluminea) in the lower Columbia River, USA Broadscale distribution, abundance and habitat associations of the invasive Asian clam (Corbicula fluminea) in the lower Columbia River, USA
The Asian clam, Corbicula fluminea, is an invasive freshwater bivalve that has established populations across the globe and is known to have deleterious effects on natural and human systems. Yet, despite being present in the Columbia River (CR) for nearly a century, little is known about this invader's basic biology and ecology in this large river system. Thus, we undertook a field study...

Susceptibility of Pallid Sturgeon to viral hemorrhagic septicemia virus genotype IVb Susceptibility of Pallid Sturgeon to viral hemorrhagic septicemia virus genotype IVb
Objective Viral hemorrhagic septicemia virus (VHSV) is an aquatic rhabdovirus causing severe disease in freshwater and saltwater fish species. The susceptibility of endangered Pallid Sturgeon Scaphirhynchus albus to VHSV genotype IVb (VHSV-IVb) infection was investigated.Methods An in vitro assessment using two Pallid Sturgeon cell lines derived from skin and spleen tissue and in vivo...

Establishing an in vitro model to assess the toxicity of 6PPD-quinone and other tire wear transformation products Establishing an in vitro model to assess the toxicity of 6PPD-quinone and other tire wear transformation products
The tire wear transformation product 6PPD-quinone (6PPDQ) has been implicated as the causative factor for broad scale mortality events for coho salmon in the Pacific Northwest. Highly variable sensitivity to 6PPDQ in closely related salmonids complicates efforts to evaluate the broader toxicological impacts to aquatic ecosystems. Our goals were to (1) validate the large range of in vivo...

Toward a national eDNA strategy for the United States Toward a national eDNA strategy for the United States
Environmental DNA (eDNA) data make it possible to measure and monitor biodiversity at unprecedented resolution and scale. As use-cases multiply and scientific consensus grows regarding the value of eDNA analysis, public agencies have an opportunity to decide how and where eDNA data fit into their mandates. Within the United States, many federal and state agencies are individually using...

Seasonal shifts in diel vertical migrations by lake-dwelling coastal cutthroat trout, Oncorhynchus clarkii clarkii, reflect thermal regimes and prey distributions Seasonal shifts in diel vertical migrations by lake-dwelling coastal cutthroat trout, Oncorhynchus clarkii clarkii, reflect thermal regimes and prey distributions
Lakes provide important habitat for salmonids that may use them as a primary feeding area between periods of reproduction. The seasonal changes in vertical thermal structure in lakes can affect the distribution of salmonids on seasonal and diel time scales as they search for, consume, and digest prey that also exploits the water column's distribution of food, temperature and light. Our...
