Extending the Stream Salmonid Simulator to accommodate the life history of coho salmon (Oncorhynchus kisutch) in the Klamath River Basin, Northern California

In this report, we apply the stream salmonid simulator (S3) to coho salmon (Oncorhynchus kisutch) in the Klamath River Basin by extending the original model to account for life history and disease dynamics specific to coho salmon. This version of S3 includes tracking of three separate life-history strategies representing the different time periods and ages at which fish leave natal tributaries suc

The Grand Caddis hatch of JASM 2022: Trichoptera natural history observations at the Joint Aquatic Sciences Meeting in Grand Rapids, Michigan (USA)

In a stroke of good luck for aquatic scientists and insect enthusiasts, the May 2022 Joint Aquatic Sciences Meeting (JASM) in Grand Rapids, Michigan coincided with a spectacular hatch of hydropsychid caddisflies. To estimate density, we enumerated caddisflies on 12 polarized window panels on the western face of the DeVos Place, which faced the Grand River. We found an average of 57.8 caddisflies p

Actionable Science

The Colorado River Basin Pilot Project is exploring new approaches for the USGS to answer complex earth systems questions identified in partnership with stakeholders, which cannot be answered through a single discipline approach. Science coproduction is a method where scientists, managers, policy makers, and other stakeholders first identify specific decisions to be informed by science, and then...

Integrated Science Approach

The USGS has a long history of delivering science and tools to help decision-makers manage and mitigate effects of drought. The timing is critical for the USGS to consolidate its diverse expertise into a single landscape-scale effort to rapidly provide integrated transdisciplinary, targeted data, tools, and models required by decision makers in the Basin. This initiative unifies USGS expertise...
