Reconnaissance of the Upper Au Sable River, a cold-water river in the north-central part of Michigan's southern peninsula, 1974

By: Hendrickson, G.E., and Doonan, C.J.

Abstract

The au sable river is one of Michiganís most popular trout streams and canoe trails. At present, interests of the different recreationists (fishermen, canoers, campers, and riverside property owners) conflict. The conflict results from the fact that the recreational potential is limited by the hydrologic characteristics of the river--its streamflow, quality of water, and character of stream channel, bed, and banks. The purpose of this 1-sheet hydrologic atlas is to describe these characteristics and to show how they relate to the recreational potential of the stream. The watershed of the upper au sable is underlain chiefly by glacial moraine and outwash deposits. The outwash deposits are composed mainly of sand and gravel, and the soils overlying them are composed for the most part of sand. The moraines also are generally sandy, but contain some silt and clay, and the overlying soils also contain some silt and clay in places. A table summarizes the streamflow characteristics of the au sable and shows how these characteristics are related to recreational potential. A table summarizes the quality-of-water characteristics of the au sable river and shows how their characteristics are related to the recreational potential of the river. (KNAPP-USGS)
