The Cedar River Watershed Unit (as established by the states of Minnesota) consists of 1,204 square miles (3,118 square kilometres) of flat or gently undulating plain. The watershed is drained by the Cedar River and several smaller streams that flow south into Iowa and eventually into the Mississippi River. Its easternmost neck is part of a broad, flat, well-drained plain, covered by a thin sheet

A variety of glacial landforms (moraines, till plains, drumlin fields and outwash plains) characterized the 3,890-square mile Mississippi and Sauk Rivers watershed. Underlying the glacial drift are Cambrian and Precambrian sedimentary rocks in the southeastern part of the watershed and Precambrian igneous and metamorphic rocks elsewhere. Surface drainage is entirely to the Mississippi River, the l

The Lake of the Woods watershed is an area of about 2,900 square miles (7,500 km), the northern limit of which is part of the boundary between the United States and Canada. Drainage is to Lake of the Woods, either directly or by the Rainy River. The watershed includes about 470 square miles (1,220 km2) of Lake of the Woods, one-third of the lake’s total area. The watershed, a part of the plain of

Runoff is the water in a river or stream that results from precipitation falling on the drainage basin. It is the net discharge into the stream from surface-water and ground-water sources with losses occurring from evapotranspiration and other consumptive uses. Runoff can be expressed by a variety of numerical values, but average depth of water over the drainage basin, in inches per year, probably

Griggs and Steele Counties, located at the eastern edge of the Williston basin, are underlain by 400 to 2,600 feet of Paleozoic and Mesozoic rocks that dip gently to the west. The Cretaceous Greenhorn, Carlile, Niobrara, and Pierre Formations lie directly beneath the glacial drift, and shale of the Pierre Formation is exposed in several places along the Sheyenne River. The Pleistocene Coleharbor F

This report contains statistical summaries of streamflow records from 74 gaging stations, which are mostly in northeastern Utah. Low- flow, high-flow, and flow-duration summaries were compiled from daily discharge values; and flows of each month are compared through correlation with flows of 1, 2, and 12 months in the future.

Northwestern Kansas, an area of 8,050 square miles (21,000 square kilometres), is a flat to gently rolling plain that is dissected by the Smoky Hill and Republican Rivers. Loessial soils underlying the plain are ideal for cultivation.The climate is semiarid with the mean annual precipitation ranging from 16 to 21 inches (41 to 53 centimetres). Precipitation occurring mainly as thunderstorms during
