| 説明 | Aerial view of Brandon Road Lock and Dam, Joliet, Ill., April 22, 2014. Brandon Road Lock and Dam has been identified by the Corps Great Lakes and Mississippi River Interbasin Study (GLMRIS) Team as the downstream control point of the Chicago Area Waterway System for a number of different aquatic nuisance species controls; the topographic and geographic positioning of the site in the hydrology of the CAWS allows it to serve as a single point of passage for any species able to move upstream toward the Great Lakes. The lock has been operational since 1933. (U.S. Army Corps photo by Dave Wethington/Released) |
