Sediment yields of Wisconsin streams

Sediment in Wisconsin streams causes economic and engineering problems in water management and reduces the value of water for nearly all uses. Sediment produces problems such as reduced reservoir capacity, navigation hazards, increased cost of water treatment, property damage, temporary loss of farmland, destruction of feeding and nesting grounds of fish, and destruction of wildlife habitat. Sediment in water also reduces the aesthetic value of surface waters and is detrimental to the State's tourist and recreation industry. The yield of sediment from a drainage basin is subject to many environmental influences. Most sediment results from the weathering and erosion of soil and rock materials. Other factors such as rainfall intensity, runoff rate, topography, rock type, soil characteristics, vegetal cover, and land use also influence the rate of sediment production and movement. An understanding of the many parameters that influence sediment yield is a basic need for managing the State's water resources. The purpose of this report is to describe the magnitude and variability of sediment in Wisconsin streams, to relate sediment yields to the local environment, and to identify areas that need further study. The report is based on sediment data from 44 stream-gaging sites throughout the State. Determination of local areas of erosion and deposition are beyond the scope of the report.

Water resources of the Crow Wing River watershed, central Minnesota

The Crow Wing River, a tributary of the Mississippi River, drains an area of about 3,760 square miles, essentially all of which is covered by glacial deposits. Topography of most of the watershed is slightly- to moderately-undulating and has local relief of up to about 50 feet. The margin of the watershed, particularly the southwestern and northwestern parts, is higher and has local relief often exceeding 150 feet. The higher areas contain numerous lakes and, in the extreme north and east parts of the watershed, are heavily forested.
