ALEXANDRIA, VIRGINIA - May 1, 2012. USACE IWR's Navigation Data Center has launched the USACE Lock Performance Monitoring System (LPMS) website at This Corps Locks website provides lock and vessel specific information derived from the Lock Performance Monitoring System. The information provided represents daily and half hourly snapshots of Freedom of Information Act (FOIA) data on U.S. flag vessels and foreign vessels operating in U.S. waterways that transit a USACE owned or operated lock structure. The site features traffic and hydrologic information submitted by the locks via LPMS. This data replaces the same data formerly available on the Navigation Information Connection. Please note that detailed company or commodity information is considered privileged information and is precluded from the Corps Locks website. Additional features are planned for future release. Also available to assist the public are Facebook and Twitter pages.
