A North American green sturgeon is slowly reeled in to the edge of a boat in the Sacramento River at Hamilton City, California. The fish was caught by U.S. Army Corps of Engineers Sacramento District deputy commander Lt. Col. Dianna Lively who joined district fisheries biologists October 13, 2023, on a fish tagging expedition to gather behavioral data of the North American green sturgeon that migrate through the river every three to five years. The data is then analyzed to determine the degree of impacts USACE civil works projects may or may not have on the species that since 2006 has been listed as threatened under the Endangered Species Act. USACE fisheries biologists have inserted telemetric tags in 85 green sturgeons over the past four years. Lively caught three sturgeons during the trip which cumulatively measured nearly 19 feet long. The largest, seen here, measured nearly seven feet long. (U.S. Army photo by Ken Wright)
