The lock Performance Monitoring System is a part of the Inland Navigation Systems Analysis program and encompasses the collection, editing, maintenance and analysis of data collected at all Corps-owned and operated locks. The data have been collected since March of 1975 and consist of information describing the traffic through the locks as well as the physical aspects of lockages. The quarterly summary of selected statistics presented in the appendix provides an overview of the traffic and operation at each lock. The quarterly report is presented as a set of three tables for each Corps District. Information reported for eack lock and chamber includes 1 A listing providing the name of the lock, the river on which the lock is and its dimensions.
