Meet Ellie, the best & sole member of the @USACEHQ Great Lakes & Ohio River Division’s Dog Patrol Team! She works at Chicago’s Lock and Dam & saves taxpayers $20K in cleanup costs by chasing away stray birds. Today is her last day this summer – thanks, Ellie! #InternationalDogDay pic.twitter.com/1h6gjbBzrG
