The Navigation Data Center (NDC) produces and stores data on lock characteristics nationwide in the Lock Performance Monitoring System (LPMS) and the Lock Characteristics database. These data sets are developed using input from surveys conducted by NDC staff. Information collected includes the physical aspects of all USACE built, maintained, owned, or operated locks. The data set captures six major characteristics including location, physical characteristics, site information, site characteristics, management information, and historical changes. A data dictionary, or other source of attribute information, is accessible at https://doi.org/10.21949/180Q-FC93 The Navigation Data Center (NDC) provides information on locks through the Lock Performance Monitoring System (LPMS), which is a web-based system used to collect and report data on vessels that traverse through Corps-owned or operated locks in near real-time. The primary purpose of the LPMS is to capture data relating to operations of locks, which acts as a planning tool for vessel operators and aids them in tracking progress of goods shipped on U.S. waterways.

Users are advised to read the rest of the metadata record carefully for additional details. Monthly summary statistics are based on data from the Lock Performance Monitoring System (LPMS). The LPMS was developed to collect a 100% sample of data on the locks that are owned and/or operated by the US Army Corps of Engineers. Each record contains data summarized monthly by lock chamber, and direction (upbound and number), cuts, hardware operations. The data are by waterway and by calendar year. The waterway files contain 5 years of data for one waterway. The calendar year files contain 1 year of data for all waterways. data is updated as deemed necessary Alexandra Schafer United States Army Corp of Engineers (USACE) Project Manager 7701 Telegraph Rd Alexandria VA 22315 United States alexandra.l.schafer@usace.army.mil party that accepts accountability and responsability for the data and ensures appropriate care and maintenance of the resource
