Hydrogeology and Stratigraphy of the Dakota Formation in Northwest Iowa

A. Munter G. A. Ludvigson B. J. Bunker Iowa Geological Survey Iowa Geological Survey Donald L. Koch Director and State Geologist 123 North Capitol Street Iowa City, Iowa 52242 Foreword An assessment of the quantity and quality of water available from the Dakota (Sandstone) Formation 1n northwest Iowa is presented in this report. The as sessment was undertaken to provide quantitative information on the hydrology of the Dakota aquifer system to the Iowa Natural Resources Council for alloca tion of water for irrigation, largely as a consequence of the 1976-77 drought. Most area wells for domestic, livestock, and irrigation purposes only partial ly penetrated the Dakota Formation. Consequently, the long-term effects of significant increases in water withdrawals could not be assessed on the basis of existing wells. Acquisition of new data was based upon a drilling program designed to penetrate the entire sequence of Dakota sediments at key loca tions, after a thorough inventory and analysis of existing data. Definition of the distribution, thickness, and lateral and vertical changes in composition of the Dakota Formation has permitted the recognition of two mem bers. Additionally, Identification of the rock units that underlie the Dakota Formation has contributed greatly to our knowledge of the regional geology of northwest Iowa and the upper midwest. -

Keyes: Opinions Concerning the Age of the Sioux Quartzite 218 IOWA ACADEMY OF SCIENCES. OPINIONS CONCERNING THE AGE OF THE SIOUX QUARTZITE. BY CHARLES ROLLIN KEYES. [Abstract.] The Sioux quartzite is a formation made up of hard, flinty beds, of considerable thickness and extent, which are exposed principally along the Sioux river, in southeastern Dakota, south western Minnesota and northwestern Iowa. It is of particular interest to Iowans, for the re~son it has been usually regarded as the most ancient geological formation occurring within the limits of the state-older than the lead-bearing rocks of north eastern Iowa, and older than the CamW-ian sandstones which lie at the base of the Mississippi bluffs in the extreme corner of the state. -

Minnesota Ground Water Bibliography
First Edition: May 1989 Second Edition: June 1990 MINNESOTA GROUND WATER BIBLIOGRAPHY By Dave Armstrong Revised by Toby McAdams First Edition: May 1989 Second Edition: June 1990 Original paper document scanned and converted to electronic format: 2004. MINNESOTA DEPARTMENT OF NATURAL RESOURCES Division of Waters St. Paul, MN ii Acknowledgements Many thanks for their willing help to Colleen Mlecoch and Char Feist, DNR librarians, and to the clerical and other library staff who assisted in the search for publications, to the Division of Waters groundwater unit staff members Jeanette Leete, Jay Frischman, Andrew Streitz, and Eric Mohring for their suggestions and patience and to Pat Bloomgren for review. Special thanks to Tami Brue, Chris Weller, and Penny Wheeler for scanning, typing, editing and word processing. iii iv PREFACE The primary objectives for this Bibliography were to provide both a localized reference to Ground Water Resource Publications, and a reference to the organizations, agencies and individuals in Minnesota who are currently publishing information on and related to ground water. The Bibliography is divided into two sections. Chapter I lists the publications of the United States Geological Survey (USGS) and the Minnesota Geological Survey (MGS). Publications which deal with a specific area are listed by area within the six DNR regions of Minnesota. These are followed by the listing of USGS and MGS publications of a general nature which deal with all of Minnesota. Chapter II contains publications from many organizations, individuals and journals. It is divided loosely into subject categories, and an index is provided at the end of the document to help locate additional subjects. -
