Adult Pacific salmon may reach spawning grounds but perish before reproducing, a phenomenon known as “prespawn mortality." Read More
“Ecological design” culverts have perceived fiscal limitations that have prevented widespread implementation and consequently hampered conservation and remediation of stream ecosystems. We addressed these perceived fiscal limitations using cost–benefit analysis to estimate the lifetime fiscal net benefits of ecological design culverts over hydraulic culverts Read More
There is a need to improve the management of recreational fisheries, and some organizations have begun piloting and implementing opt-in, self-reporting smartphone and tablet apps to further that goal. We began the process of developing a methodology for assessing the utility of these apps for management by comparing the Snook and Gamefish Foundation’s iAngler app... Read More
Environmental DNA (eDNA), the nuclear or mitochondrial DNA shed from an organism into its environment, is a rapidly evolving tool for monitoring the distribution of aquatic species. A new study published in Transactions of the American Fisheries Society discusses the ability of eDNA to accurately predict the presence, relative abundance, and biomass of wild Brook... Read More
Graphical function mapping provides a simple method for improving communication within interdisciplinary research teams and between scientists and nonscientists. Read More
On February 24, 2014, a hydro mechanic from Grant County Public Utility District (PUD) discovered an anomaly in the handrail and track on the deck of Wanapum Dam. Read More
Decision support tools can aid decision making by systematically incorporating information, accounting for uncertainties, and facilitating evaluation between alternatives. Read More
