HYDROGRAPHIC SURVEY BRIEF
The U.S. Army Corps of Engineers’ navigation mission is to provide safe, reliable, efficient, and environmentally sustainable waterborne transportation systems (channels, harbors, and waterways) for movement of commerce, national security, and recreation. The mission of the Galveston District Navigation Branch is to manage federal Navigation Projects along the Texas coastal region. The Galveston district hydrographic survey webpage provides the latest hydrographic survey products and raw survey data for download.
The information depicted on these survey maps represent the results of surveys made on the dates indicated and can only be considered as indicating the general conditions existing at that time. These conditions are subject to rapid change due to shoaling events. A prudent mariner should not rely exclusively on the information required here. Required by 33 CFR 209.325
The U.S. Army Corps of Engineers developed eHydro to provide enterprise performance-based analyses and budgeting for coastal navigation channels through geospatial data to be used for, uniform method of data dissemination and comparison of latest conditions on coastal navigation channels. The Galveston district processes and reports channel condition data through the eHydro reporting process for all high and moderate commercial use channels, followed by low use channels.
