Each year the U.S. Army Corps of Engineers contracts with the City of Lewiston Police Department to provide police patrol of the levee system. Officers provide patrols during the entire year on the levee system within the city. It is up to the individual officer whether he or she patrols the levee on foot or on a specially equipped police bicycle.
The administrative corporal is responsible for scheduling the patrols which includes added coverage on holidays, during special events, and during hours the levee system is most frequented.
