UMRR HNA-II Aquatic Areas

Citation

U.S. Army Corps of Engineers’ Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element. 2017, UMRR HNA-II Aquatic Areas: La Crosse, WI, https://doi.org/10.5066/F7VD6WH8.

Summary

The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS) from 1:15,000-scale color infrared aerial photos. These data have been used to create a variety of products, one of which is a data set used to classify aquatic areas. The geographic extent of the UMRS is the Mississippi River floodplain from Cairo, IL to Minneapolis, MN and the Illinois River floodplain from its confluence with the Mississippi near Grafton, IL to Lake Michigan.

Purpose

The Upper Midwest Environmental Sciences Center administers the US Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) Program, Long Term Resource Monitoring (LTRM) element, authorized under the Water Resources Development Act of 1986 (Public Law 99-662). The mission of the UMRR-LTRM is to provide decision-makers with information to maintain the Upper Mississippi River System (UMRS) as a viable large river ecosystem given its multiple-use character. The long-term goals of the program are to understand the system, determine resource trends and impacts, develop management alternatives, manage information, and develop useful products. The creation and distribution of aquatic areas data for the UMRS aids the Center in meeting these goals through the Habitat Needs Assessment II (HNA-II) project. The HNA-II will utilize many new data and information products, as well as modeling approaches that were stated as limitations of HNA-I. In addition, previous efforts to document desired future conditions of the UMRS will be incorporated into the assessment. Finally, additional input from river resources and other technical teams will help guide the process.
