The Flood Control Collection contains materials on the subjects of flood events, flood
control, erosion by water, and storm water management. The materials span the years 1910
to 1979, with the bulk produced between 1938 and 1953. The materials are in fair to good
condition. Researchers may use the collection without restrictions.
The National Agricultural Library’s Special Collections received the materials in Box 1
from an unknown source prior to 2002. The USDA Natural Resources Conservation Service
(NRCS) office in Portland, Oregon transferred additional materials to Special
Collections in 2017. The original collection was arranged and described by Jennifer Wang
in 2002. The addition was incorporated into the collection in 2018 by Diane Wunsch.
On April 27, 1935, Congress established the Soil Conservation Service (SCS) as a
permanent agency in the U.S. Department of Agriculture (USDA). The creation of the
agency highlighted the efforts of Hugh Hammond Bennett to inform the public about the
problem of soil erosion. Bennett was appointed the first Chief of SCS.
Watershed planning became an important part of the agency’s mission in the 1930s.
Bennett recognized that successful soil and water conservation needed to begin at the
watershed level. SCS organized its early demonstration projects on a watershed
A series of laws formed the basis of SCS erosion control programs. The Flood Control Act
of 1936 authorized SCS to study methods for erosion control and flood prevention. The
Flood Control Act of 1944 enabled the agency to begin work on its first 11 watershed
projects. Passage of the Agricultural Appropriations Act of 1953 authorized 63 more
projects. Congress enacted the Watershed Protection and Flood Prevention Act in 1954.
With this law, SCS gained permanent watershed planning authority.
In 1994, SCS was renamed the Natural Resources Conservation Service (NRCS).
Scope and Content Note
The Flood Control Collection contains reports, publications, correspondence, notes,
photographs, audio recordings, maps, and data regarding floods and flood control in the
United States. The USDA Soil Conservation Service produced most of these items. There
are a few pieces authored by other individuals and agencies. The collection also
includes articles and addresses written for professional organizations, such as the
American Society of Agricultural Engineers and the Society of American Foresters.
