2002 UMRS Land Cover Land Use Pool 08


Publication Date
Time Period


The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created a high-resolution land cover/use data set for Mississippi River Navigation Pool 8 from 1:10,000-scale color infrared aerial photos collected August 26th, 2004. The photos were interpreted using a 1-acre 10% minimum vegetation cover to delineate land cover/land use, percent vegetation cover, tree height, and hydrology regime. The geographic extent of Navigation Pool 8 is the section of the river upstream of Lock and Dam 8 (river mile 679.2) located near Genoa, WI, to Lock and Dam 7 (river mile 702.5) located near Dresbach, MN.

The 2002 Pool 8 land cover/use data was created to aid regional biologists and researchers in their analysis of the effects of the 2000 and 2001 Pool 8 draw downs. During the draw downs, the U.S. Army Corps of Engineers deliberately lowered the summertime water levels maintained at lock and dam 8. This was done to mimic water level changes that used to occur within the river system prior to the construction of the lock and dams.
