The systematic measurement of the suspended sediment transported by streams has been limited to special investigations with the exception of a few daily sampling stations operated in southwestern United States to provide data on the probable life of present and proposed reservoirs. However, the vital importance of records of sediment discharge of streams in other sections of the United States has become apparent in connection with a variety of projects relating to river control and beneficial use of the nation's water resources. In the last few years, proposed developments in Iowa for flood control, navigation, drainage systems, recreational facilities, and water power and the paucity of quantitative data on soil erosion have revealed a need for factual information on the sediment discharge of Iowa rivers. This situation was recognized by the 50th General Assembly of Iowa which authorized the Iowa Geological Survey to participate in a cooperative program involving among other items the collection of concurrent records of water and suspended sediment discharge. This program has been integrated with then needs of investigations of the several U. S. Engineer Districts and other federal and state agencies operating in Iowa.
