Title:The heart of the Sangamon: an inventory of the region's resources
Subject(s):Natural Resources --Sangamon River Watershed
Environmental protection --Sangamon River Watershed
Ecosystem management --Sangamon River Watershed
Geographic Coverage:Illinois
Abstract:The Sangamon River meanders across central Illinois for more than 240 miles. Its waters accumulate in southeast McLean County and northwest Champaign County and eventually empty into the Illinois River near Beardstown. Near its headwaters, the gathering Sangamon is scarcely a river at all. In its lower reaches, which have been straightened by engineers, it is scarcely a natural river. In between is the heart of the Sangamon, and from Gibson City to its meeting with Mosquito Creek near Illiopolis, the river retains much of its character from the days before settlement. The heart of the Sangamon drains 1,220 square miles, most of it in Macon and Piatt counties. The countryside is part of a massive "till" plain that blankets most of east central Illinois. Till is the jumbled rock debris -mostly gravels, sands, and clays -left behind by glaciers. (Till can be seen locally along streams where erosion has exposed the subsurface.) The bulldozing ice ground down the high spots of the old landscape and filled in the low ones, so that the most obvious trait of today's terrain is its lack of obvious traits.
