The Navigation Data Center had several objectives in developing the U.S. Locks Data. These objectives support the concept of a National Spatial Data Provide public access to national Locks data. Foster interagency and intra-agency cooperation through data sharing. Provide a mechanism to integrate Locks data (U.S. Army Corps of Engineers Port/Facility and U.S. Coast Guard Accident Data, for example) Provide a basis for intermodal analysis. Assist standardization of Locks entity definitions (Ports/Facilities, Locks, etc.). Provide public access to the National Locks Network, which can be used as a base map to support graphical overlays and analysis with other spatial data (Locks and modal network/facility databases, for example). Provide reliable data to support future Locks and intermodal applications. Source of Data The data included in these files are based upon the Annual Summary of Lock Statistics published by the U.S. Army Corps of Engineers/CEIWR, Navigation Data Center. The data are collected at each Corps owned and/or operated Lock by Corps personnel and towing industry vessel operators. This data was collected from the US Army Corps of Engineers and distributed on the National Transportation Atlas Databases (NTAD) 2015.
