| Mission of the SD
Geological Survey |
| |
| To conduct geologic
studies, hydrologic studies, and research;
and to collect, correlate, preserve, interpret, and disseminate
information, leading to a better understanding of
the geology and hydrology of South Dakota. Special emphasis
is placed on ground-water quantity and quality and
other natural resources of economic value. The Survey
has no regulatory authority; instead, it provides information and
interpretations on natural resources and related issues, and assists
agencies and individuals in making well-informed
decisions. |
SDGS History
The South Dakota Geological Survey was established by the
legislature on March 6, 1893. From 1893 to 1903, the first State Geologist, J.E. Todd, led
a pioneering effort to establish the Survey as a State scientific institution, through
various reconnaissance surveys of the State.
From 1903 to 1914, under State Geologist, Ellwood C. Perisho,
the Survey continued with reconnaissance work and expanded its role in Natural Science
education, with geology being one of several fields addressed.
From 1915 to 1926, the method of work changed from reconnaissance surveys
to more detailed investigations under State Geologist, Freeman Ward.
From 1926 to 1957, the Survey was under the guidance of State
Geologist, E.P. Rothrock. The Great Depression shifted the Survey's priorities to
concentrate on mineral resources, which would benefit the State. After the depression
years, the Survey began to broaden the types of geologic investigations that it undertook.
From 1957 to 1992, the Survey continued to
expand its investigations across the State. State Geologists Allen F. Agnew, Duncan J.
McGregor, and Merlin J. Tipton, significantly increased the number and types of
cooperative investigations.
From 1992 to the present, State Geologists Cleo M. Christensen and Derric L. Iles have
concentrated efforts to complete the countywide assessments of geologic and hydrologic
resources in the eastern half of the State. With the completion of these countywide
studies nearing, an increased focus on the protection of the State's natural resources has
evolved. The Survey has begun long term efforts to monitor the water quality of the
State's shallow aquifers as well as produce more detailed mapping of the shallow aquifers
in the State.
