U.S. Army Corps of Engineers Sacramento District team member David Colby, environmental manager, lowers a Juvenile Salmon Acoustic Telemetry System (JSATS) receiver into the lower Sacramento River to conduct a telemetry survey that collects data on tagged green sturgeon on Sept. 10, 2025, in Stockton, California. U.S. Army Corps of Engineers Sacramento District environmental managers and Bryte Yard craftsmen collaborate and conduct 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.
