    Telemetry Surveys: Tracking Life Beneath the Surface

    Environmental manager Ashley Lopez, fisheries biologist David Colby, and Bryte Yard technicians deployed acoustic telemetry receivers along the lower Sacramento River to monitor juvenile salmon and green sturgeon migration patterns and habitat use. The data collected helps assess the impact of flood control projects like the Sacramento River Bank Protection Project on aquatic species. Shared with agencies such as the National Marine Fisheries Service (NMFS), the telemetry results support environmental compliance and guide mitigation efforts for federally protected species. This collaboration with partners like the California Department of Water Resources (DWR) and UC Davis ensures that flood risk management projects are balanced with environmental stewardship.
