Abstract

This report, Water-Supply Bulletin No. 6, on the streamflow records of Iowa for the period 1950-55 is part of the continuing series of basic data reports on the water resources of the State. Although these streamflow records have been previously published in several Federal publications, they are collected and conveniently arranged here for maximum usefulness to the people who will require them. Adequate information on the quantity of surface water available and the range of stages that has been experienced is essential in the construction and operation of hydraulic works of all kinds,including structures for flood protection, navigation developments, municipal supplies, power and industrial plants, irrigation and drainage of lands, pollution control, and conservation of water for various uses. Streamflow data are also necessary for the proper design of bridge and culvert openings, the establishment of highway and railway grade elevations, as well as the maintenance and operation of all facilities and developments utilizing the surface water resources of Iowa.The systematic collection of streamflow records in Iowa was begun in 1914 on a cooperative basis by the State and Federal governments, although some authenticated records extend back to 1873. Measurements of stage, flow, sediment, and mineral content and temperature of Iowa lakes and streams are being continued on a systematic state-wide basis, and it is hoped that the results can be arranged, printed, and distributed at five-year intervals.
