Origin...

The US Army Corps of Engineers has been regulating activities in the nation's waters since 1890. Until the 1960s the primary purpose of the regulatory program was to protect navigation. Since then, as a result of laws and court decisions, the program has been broadened so that it now considers the full public interest for both the protection and utilization of water resources. These boundaries represent USACE regulatory districts. Attribute information includes an address, telephone number and url for each district. Updated AUG 2023.

The dataset presented here represents a circa 1932 land/water delineation of coastal Louisiana used in part of a larger study to quantify landscape changes from 1932 to 2016. The original dataset was created by Dunbar, and Britsch, and Kemp (2006). The original dataset is citable as: Dunbar, J. B. and Britsch, L. D., 2006. Land Loss in Coastal Louisiana 1932-2001. Map 1. Engineer Research and Development Center, Vicksburg, MS, Technical Report, ERDC/GSL TR-05-13, Land Loss Map 1 through 7. The USGS Wetland and Aquatic Research Center altered the original data by improving the geo-rectification in specific areas known to contain geo-rectification error, most notably in coastal wetland areas in the vicinity of Four League Bay in western Terrebonne Basin. The dataset contains two categories, land and water. For the purposes of this effort, land includes areas characterized by emergent vegetation, upland, wetland forest, or scrub-shrub were classified as land, while open water, aquatic beds, and mudflats were classified as water. For additional information regarding this dataset (other than geo-rectification revisions), please contact the dataset originator, the U.S. Army Corps of Engineers (USACE).

JALBTCX National Coastal Mapping Program Derived Products: Great Lakes & Ohio River DivisionThe layers depicted in this web map were developed to serve regional geospatial data needs of USACE Districts and agency partners to discover and download products derived from USACE National Coastal Mapping Program (NCMP) high resolution, topo-bathymetric lidar and imagery. The USACE NCMP acquires high-resolution, high-accuracy topographic/bathymetric lidar elevation and imagery on a recurring basis along the sandy shorelines of the US. The program's survey footprint includes an approximately 1-mile wide swath of topography, bathymetry and imagery 500-m onshore and 1000-m offshore. The standard suite of NCMP data products include topographic/bathymetric lidar point clouds, digital surface and elevation models, shoreline vectors and both true-color and hyperspectral imagery mosaics. Value-added derivative information products may include laser reflectance images, landcover classification images, volume change metrics, and the products to help address District project requirements. USACE Headquarters initiated the NCMP in 2004. The program's update cycle follows counter-clockwise along the US West Coast, Gulf Coast, East Coast and Great Lakes approximately every 5 years. Surveys in support of USACE project-specific missions and external partners are included constituent to the current NCMP schedule and reimbursable funding. All work is coordinated with Federal mapping partners through the Interagency Working Group on Ocean and Coastal Mapping (IWGOCM) and the 3D Elevation Program (3DEP).NCMP operations are executed by the Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX). The JALBTCX mission is to perform operations, research and development in airborne lidar bathymetry and complementary technologies to support the coastal mapping and charting requirements of the US Army Corps of Engineers, the US Naval Meteorology and Oceanography Command and the National Oceanic and Atmospheric Administration. Survey operations are conducted worldwide using the Coastal Zone Mapping and Imaging (CZMIL) system and other industry-based coastal mapping and charting systems. CZMIL is JALBTCX's in-house survey capability that includes and Optech International, CZMIL 03-1 lidar instrument with simultaneous topographic and bathymetric capabilities. CZMIL is integrated with an Itres CASI-1500 hyperspectral imager and an 80 MP Leica RCD30 RGBN camera. CZMIL collects 10-kHz lidar data with spatially- and temporally-concurrent digital true-color and hyperspectral imagery.

This map is intended as a component of the Map Tour - "U.S. Army Corps of Engineers (USACE) Dams in the ACF"This map displays the 5 dam projects USACE has within the Apalachicola, Chattahoochee, and Flint (ACF) River Basin.

The flood plains were created using the USACE Engineering Research Development Center – AutoRoute hydraulic modeling software. AutoRoute utilizes a steady-state, normal flow solver, making AutoRoute incapable of assessing some of the more typical, yet complex, hydraulic phenomena, such as backwater effects. The floodplains were developed to rapidly assess the increased flood risk that is generally associated with post-wildfire hydrology or large changes to a watershed from a wildfire. The floodplains are intended to be used as a tool by flood disaster responders and other officials so they can prepare resources for a potential post-wildfire flood event. The limits of flooding shown should only be used as a guideline for emergency planning and response actions. A detailed hydrologic and hydraulic calibration effort was not completed to validate the results of this assessment.

In 2016, the U.S. Army Corps of Engineers (USACE) started collecting high-resolution multibeam echosounder (MBES) data on Lake Koocanusa. The survey originated near the International Boundary (River Mile (RM) 271.0) and extended down the reservoir, hereinafter referred to as downstream, about 1.4 miles downstream of the Montana 37 Highway Bridge near Boulder Creek (about RM 253). USACE continued the survey in 2017, completing a reach that extended from about RM 253 downstream to near Tweed Creek (RM 244.5). In 2018, the U.S. Geological Survey (USGS) Idaho Water Science Center completed the remaining portion of the reservoir from RM 244.5 downstream to Libby Dam (RM 219.9). The MBES data collected in 2016 and 2017 by the USACE was combined with the MBES data collected in 2018 by the USGS. The USGS also developed a stage-area-capacity table at one-foot intervals from the minimum pool elevation (2,290.84 ft) to the maximum pool elevation (2462.84 ft) using the new bathymetry data. The updated stage-area-capacity table will be compared to the current usable storage estimate of 4,979,500 acre-feet and published in a USGS Scientific Investigations Map. A 10-ft digital elevation model (DEM) and minimum and maximum pool contours also were generated from the bathymetric data and are provided in this data release.

The National Levee Database is a dynamic, searchable inventory of information about levees, and a key resource supporting decisions and actions affecting levee safety. Â It provides information about the location and condition of levees and floodwalls, displayed in an easy-to-use map interface, as well as reports, inspection summaries, and other records. Â It includes detailed information about the levees in the Levee Safety Program, as well as a growing library of available information on levees outside of the USACE program.

The flood plains were created using the USACE Engineering Research Development Center – AutoRoute for all areas with the exception of using the USACE Engineering Research Development Center – River Analysis System (HEC-RAS) hydraulic modeling software, version 6.2 in the Mora area. AutoRoute utilizes a steady-state, normal flow solver, making AutoRoute incapable of assessing some of the more typical, yet complex, hydraulic phenomena, such as backwater effects. HEC-RAS utilizes a two-dimensional (2D) unsteady flow analysis algorithm. This analysis incorporated breaklines and 2D mesh modifications to better represent terrain features in the simulation. Wood and scrub vegetation features were not represented in the bare earth LIDAR but were considered via Manning’s roughness values. Bridges and buildings were not included in the bare earth LiDAR terrain surface and were not implemented via modifications in HEC-RAS RASMapper.
