If you are experiencing accessibility issues and need assistance, please contact our Helpdesk by phone at 1-800-457-3642 or by e-mail at [email protected]. For assistance with publications that include maps, graphs, or similar forms of information, you may also wish to contact our State or local office. You can locate the correct office and phone number at http://offices.sc.egov.usda.gov/locator/app. 3 How To Use This Soil Survey This publication consists of a manuscript and a set of soil maps. The information provided can be useful in planning the use and management of small areas. To find information about your area of interest, locate that area on the Index to Map Sheets. Note the number of the map sheet, and turn to that sheet. Locate your area of interest on the map sheet. Note the map unit symbols that are in that area. Turn to the Numerical Index to Map Units, which lists the map units by symbol and name and shows the page where each map unit is described. The map unit symbols and names also appear as bookmarks, which link directly to the appropriate page in the publication. The Contents shows which table has data on a specific land use for each soil map unit. Also see the Contents for other sections of this publication that may address your specific needs. 4 This soil survey is a publication of the National Cooperative Soil Survey, a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (formerly the Soil Conservation Service) has leadership for the Federal part of the National Cooperative Soil Survey. Major fieldwork for this soil survey was completed in 2001. Soil names and descriptions were approved in 2002. Unless otherwise indicated, statements in this publication refer to conditions in the survey area in 2002. This survey was made cooperatively by the Natural Resources Conservation Service and the Illinois Agricultural Experiment Station. It is part of the technical assistance furnished to the McDonough County Soil and Water Conservation District. Financial assistance was provided by the McDonough County Board and the Illinois Department of Agriculture. Soil maps in this survey may be copied without permission. Enlargement of these maps, however, could cause misunderstanding of the detail of mapping. If enlarged, maps do not show the small areas of contrasting soils that could have been shown at a larger scale.

Points of interest include bridges, dams, gaging stations, county lines, hydrologic unit boundaries, and major tributaries. Drainage areas are presented for selected sites, including total drainage area for any streams draining at least 100 square miles. INTRODUCTION Expansion of water-resource investigations within the State of Illinois has amplified the need for a common index to locations on streams. A common index would aid in the coordination of various stream-related activities by facilitating data collection and interpretation.

Two basins in which little were known of the current mussel communities are the La Moine and Spoon Rivers in western Illinois. The mussel communities were sampled at 87 locations within these two basins between 2009-2011 and historical mussel communities served as a comparison within these basins. The current samples produced 1,171 live mussels representing 21 species from the La Moine River basin and 1,291 live individuals representing 21 species from the Spoon River basin. Forty-three species have been collected from the Spoon River basin since 1892. The La Moine River basin has not been sampled as thoroughly as the Spoon and only 25 species have been documented from this basin since the first samples in the late 1980’s.

Ph.D., President, Southern Illinois University STATE WATER SURVEY DIVISION WILLIAM C. ACKERMANN, Chief URBANA 1966 FOREWORD In many parts of Illinois, reservoir storage of water is an important means of increasing usable water supplies to enable community growth and develop• ment. Because of this significance for water resources of the future, the Illinois State Water Survey initiated a reconnaissance investigation to identify potential sites within the state where surface storage of water is physically feasible. This report provides information on potential and existing reservoirs in 33 counties of north-central Illinois. Publications containing similar data for 17 southern and 29 south-central counties have been published as Reports of Investi• gation 31 and 54, respectively. Data are being tabulated in preparation for a report on 23 northern counties.
