Data-driven insights aid salmon recovery
smarter decision making
Managing outflows from Shasta Dam to protect the endangered Winter Run Chinook Salmon is tricky business. Every release must balance flow rate, temperature, and fish locations to keep conditions optimal. FlowWest’s Shasta Operations for Winter Run (SHOWR) web application dashboard provides quick insights on all of these important parameters to drive release decisions. The dashboard page was designed collaboratively with water managers and fisheries experts to give users a simplified yet informative view of the system.
power to stakeholders
For stakeholders who want to drill into the details, the Temperature and Flow pages on SHOWR showcase analytics, visualizations, and context for both new and expert users engaged in flow management for Winter Run. Temperature is the most critical component of Winter Run management and SHOWR makes comparisons to standards and conditions in previous years extremely easy.
Precision Management
The numbers and locations of Winter Run in the system drive management needs. The Winter Run page of SHOWR grew out of our work with the California Department of Fish and Wildlife (CDFW) and provides near real-time access to the latest Winter Run aerial survey data. Users can view current and historical counts, as well as spawning locations at the reach level. We also collaborated with salmon life history experts to build in functionality that forecasts expected emergence data for baby Winter Run incubating in their gravel nests, allowing users to forecast operations and determine the need for temperature management flow releases.
