The Transportation Operational Waterborne Statistics (TOWS) Database
TOWS provides information on the movement of foreign and domestic vessels and commodities with an origin or destination in the United States. TOWS includes information on navigation points of interests, the usage of waterways ports, and USACE projects. Navigation points of interest data are published quarterly and all other data is updated annually. Federal agencies with a navigation related missions are primary users of NDC and WCSC data products. However, several federal agencies in particular regularly use the data or contribute to the overall data collection process, improving the final output. The Department of Energy U.S. Energy Information Administration (EIA), for example, uses data from WCSC (TOWS) related to specific energy commodities.
