Early Research

In its early years, the Hydraulics Laboratory focused on practical research aimed at solving real-world problems. This research addressed subjects such as water power, road culverts, weather and streamflow, plumbing issues, river sediment, weir and current meter measurements, water flow down the Mississippi River and over the Keokuk Dam spillways, and even the establishment of Iowa’s State Park system. Research was often performed under contract or in conjunction with a government agency, several of which established sub-offices within the Hydraulics Laboratory.

This record group, consisting of 15 archival boxes, includes papers dealing with all aspects of projects performed between 1920 and approximately 1940 (World War II): research contracts and arrangements, data sets, correspondence and discussion notes, and resulting speeches, reports, and published and unpublished papers. A number of high-quality original photos are also included. For information on contemporaneous hydrology efforts, also see the record group titled Ralston Creek Data and Reports.
