    • Summaries of Selected SSURGO Soil Attributes Within the Lake Michigan Diversion Accounting (LMDA) System

    Metadata Updated: September 15, 2025

    As part of the Lake Michigan Diversion Accounting (LMDA), the U.S. Army Corps of Engineers, Chicago District (USACE-Chicago) uses Hydrological Simulation Program-Fortran (HSPF) models to estimate runoff from the ungaged portion of the diverted Lake Michigan watershed. Simulation accuracy is evaluated at nine gaged watersheds in or adjacent to the diverted watershed. This data release consists of an Excel file containing 18 Soil Survey Geographic Database (SSURGO) attributes summarized using various aggregation methods for gaged and ungaged areas in the LMDA system. The gaged areas are comprised of the nine gaged watersheds used for HSPF model calibration and three gaged upstream basins. The ungaged areas are comprised of four sewered areas known as special contributing areas (SCAs) and two ungaged areas: the Lower Des Plaines River and the Calumet River. These data were derived from county-level SSURGO data for Illinois and Indiana.
