Water resources of the Kettle River watershed, east-central Minnesota
The topography of the Kettle River watershed is formed primarily by glacial deposits that mantle the bedrock. The glacial deposits are generally less than 100 feet thick. Bedrock consists of several types and occasionally crops out at land surface. Topography ranges from gently rolling to steeply undulating. About 1,060 square miles is drained by the Kettle River and its tributaries, and about 510 square miles by smaller streams that are direct tributaries to the St. Croix River. Peat and swamp areas are common, particularly in the eastern part of the area. Most of the watershed is forested, mainly with hardwoods.
