The U.S. Army Corps of Engineers Sacramento District conducts telemetry surveys to close critical data gaps on green sturgeon passage in the lower Sacramento River, providing valuable information to partner agencies for setting river flow requirements, managing dam releases, and improving the survival of this federally protected species.

    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.

The sites range in size from as small as a football field to an area as large as New York City. Fortunately, the U.S. Army Corps of Engineers Sacramento District and its partner agencies are committed to discovering and removing hazardous remnants of past military activities before anyone else.

    Imagine an adventurous day of hiking deep into one of Utah’s rugged slot Canyons. Sure it’s a bit cloudy, but rain isn’t forecast in the area for another two hours. What you don’t know, is that it’s already pouring a couple miles upstream with water levels rising fast. And all that water is headed your way.
