U.S. Army Lt. Col. Dianna Lively reels in a 78.5-inch a North American green sturgeon as senior fisheries biologist Robert Chase helps pull the fish closer to their boat during an October 13, 2023, telemetric tagging expedition on the Sacramento River in Hamilton City, California. Lively, the USACE Sacramento District deputy commander, joined Chase to help 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.
