Bathymetric data for the Upper Mississippi and Illinois Rivers -- La Grange Pool

Metadata Updated: November 12, 2020

Water depth is an important feature of aquatic systems. On the Upper Mississippi River System (UMRS), water depth data are important for describing the physical template of the system and monitoring changes in the template caused by sedimentation. Although limited point or transect sampling of water depth can provide valuable information on habitat character in the UMRS as a whole, the generation of bathymetric surfaces are critical for conducting spatial inventories of the aquatic habitat. The maps are also useful for detecting bed elevation changes in a spatial manner as opposed to the more common method of measuring changes along transects. The Upper Midwest Environmental Sciences Center (UMESC) has been collecting bathymetric data within the UMRS since 1989 in conjunction with the Long Term Resource Monitoring Program (LTRMP).

Access Constraints Use Constraints: These data should not be solely relied on for safe navigation. Water levels do change frequently with changes in the river bottom and water levels. Also the maps do not attempt to document the locations of submerged snags, tree stumps and other potential hazards., Access Constraints: Although these data have been processed successfully on a computer system at the U.S. Geological Survey, no warranty has been expressed or implied regarding the individual use of the data or aggregate use with other data, nor shall the act of distribution constitute any such warranty. It is strongly recommended that these data are directly acquired from a U.S. Geological Survey server and not indirectly through other sources which may have changed the data in some way. It is also strongly recommended that careful attention be paid to the contents of the metadata file associated with these data.
