The fish-rescue team members Rhonda Lucas and Sean McDuff measure a 6-foot-long white sturgeon rescued from the bottom of the Hiram M. Chittenden Locks during the annual maintenance pump out November 10. Each year, Corps natural resource staff, fish biologists, scientists and volunteers go on a fish-rescue mission when the locks are drained. To ensure Endangered Species Act listed fish are safe, the team must capture, haul them out of the 50-foot deep chamber and release them. The team doesn’t limit its efforts to ESA listed species and this year the rescue included an estimated 100-pound sturgeon.
