The Lock Performance Monitoring System (LPMS) and Lock Characteristics database provides Corps operators, planners, and managers with information on the use, performance, and characteristics of the Corps' national system of locks. LPMS consists of data collected at most Corps-owned and/or Corps-operated locks. Data is collected at each lock and electronically transmitted to the central database which is managed and distributed by NDC. The data, from years 1980 to present, includes the number of vessels and barges locked; type and dates of lockages; durations of, and causes for, periods of lock unavailability; barge type, size, and commodity type; and tonnages carried. Statistics are published monthly for selected key locks and annually for all locks. For Corps personnel only, direct on-line database access is available.
