Nelson Geological Science Field Trip Guidebook 2009A April 18, 2009 May 2, 2009 Institute of Natural Resource Sustainability ILLINOIS STATE GEOLOGICAL SURVEY Cover photograph: View of the Mackinaw River (photograph by W.T. Frankie). Acknowledgment The information in the first part of this guidebook is adapted from ISGS FieldTrip Guidebook 2004A, Guide to the Geology of the Pekin Area, Tazwell and Mason Counties, Illinois, by Wayne T. Frankie, Russell Jacobson, and Robert S. Nelson. Geological Science Field Trips The Illinois State Geological Survey (ISGS) conducts four tours each year to acquaint the public with the rocks, mineral resources, and landscapes of various regions of the state and the geological processes that have led to their origin. Each trip is an all-day excursion through one or more Illinois counties. Frequent stops are made to explore interesting phenomena, explain the processes that shape our environment, discuss principles of earth science, and collect rocks and fossils. People of all ages and interests are welcome. The trips are especially helpful to teachers who prepare earth science units. Grade school students are welcome, but each must be accompanied by a parent or guardian. High school science classes should be supervised by at least one adult for every ten students. The inside back cover shows a list of guidebooks of earlier field trips. Guidebooks may be obtained by con- tacting the Illinois State Geological Survey, Natural Resources Building, 615 East Peabody Drive, Cham- paign, IL 61820-6964 (telephone: 217-244-2414 or 217-333-4747).

In 2009, a project funded by a US Fish and Wildlife Service State Wildlife Grant was undertaken to survey and assess the freshwater mussel populations at wadeable sites from 33 stream basins in conjunction with the Illinois Department of Natural Resources (IDNR)/Illinois Environmental Protection Agency (IEPA) basin surveys. Inclusion of mussels into these basin surveys contributes to the comprehensive basin monitoring programs that include water and sediment chemistry, instream habitat, macroinvertebrate, and fish, which reflect a broad spectrum of abiotic and biotic stream resources. These mussel surveys will provide reliable and repeatable techniques for assessing the freshwater mussel community in sampled streams. These surveys also provide data for future monitoring of freshwater mussel populations on a local, regional, and watershed basis. Agency Contacts Kevin S.

  • The Mackinaw River
    The Mackinaw River Location: The Mackinaw River originates in Ford County near Sibley, and flows in a westerly direction for 130 miles before joining the Illinois River downstream of Pekin. The associated watershed is an area of 1,138 square miles, and covers parts of 6 central Illinois counties. The majority of the river is in McLean, Woodford, and Tazewell counties, with the river flowing through only a few cities or towns, such as Colfax, Lexington, Goodfield, and Mackinaw. Characteristics: The Mackinaw River begins as a drainage ditch near Sibley, and begins to meander near Colfax, where a thin band of trees begin. Trees line most of the banks of the river all of the way to the Illinois River, with larger forests found in the middle reaches with frequent gaps due to agricultural fields. The Mackinaw varies in depth from 1-6 feet and has an average width of 70 feet. The water level is extremely variable, with frequent flooding in the spring, and is very nearly dry during times of prolonged drought. Major tributaries include Henline Creek,Turkey Creek, Money Creek, Sixmile Creek, Wolf Creek, Denman Creek, Panther Creek, Walnut Creek, Rock Creek, Mud Creek, Prairie Creek, Little Mackinaw Creek, Dillon Creed, and Hickory Grove Ditch. The Biological Stream Characterization rated all segments of Henline, Panther, and Walnut Creeks and the Mackinaw River from Denman Creek to Mud Creek, and upstream from Money Creek as “A” streams, Unique Aquatic Resource (the highest ranking possible). Two segments of the Mackinaw are recognized as Biologically Significant Streams due to the fish and mussel diversity.

  • Sand and Gravel Resources of Tazewell County, Illinois
    STATE OF ILLINOIS DEPARTMENT OF REGISTRATION AND EDUCATION SAND AND GRAVEL RESOURCES OF TAZEWELL COUNTY, ILLINOIS Ralph E. Hunter ILLINOIS STATE GEOLOGICAL SURVEY John C. Frye, Chief URBANA CIRCULAR 399 • 1966 llllli[llmilli[~~~i~~n~~~~~~3 3051 00004 0000 1111 SAND AND GRAVEL RESOURCES OF TAZEWELL COUNTY, ILLINOIS Ralph E. Hunter ABSTRACT Tazewell County has large amounts of sand and gravel, most of which were deposited by meltwater from glaciers during the Pleistocene Epoch or Ice Age. These deposits are found principally in valleys that served as major channels for the meltwater, in the vicinity of the Il­ linois River, Mackinaw River, and Farm Creek. Smaller amounts are found in deposits from glacial meltwater away from these streams, in sand dunes, and in stream alluvium. Geographical locations of the deposits have been mapped on the scale 1:62, 500. INTRODUCTION Purpose of Study Increasing amounts of sand and gravel are required for construction in the growing urban areas of Illinois and for improvement of the state highway network. In response to the need for information regarding these resources, the Illinois State Geological Survey is engaged in a program to evaluate or, in places, re­ evaluate the sand and gravel resources of the state. This report, covering Taze­ well County (fig. 1), is a part of that program. Pekin and East Peoria, and their §iuburbs, cover extensive sand and gravel deposits, which therefore are unavailable for commercial exploitation. As these cities continue to grow, resources remaining in the county will become increasingly important as reserves to supply the needs of the area.

Wilson George S. Roadcap Beverly L. Herzog David R. Larson Derek Winstanley Title: Hydrogeology and Ground-Water Availability in Southwest McLean and Southeast Tazewell Counties, Part 2: Aquifer Modeling and Final Report Abstract: An assessment of the aquifer characteristics and ground-water availability has been completed for one of the largest sand-and-gravel aquifers in Illinois, the Sankoty-Mahomet Sand aquifer, in the confluence area of the Mahomet and Mackinaw Bedrock Valleys in McLean and Tazewell Counties. Based on data gathered during the field portion of the study, a ground-water flow model was developed that simulates the effects of a hypothetical well field for various locations within the study area. It was used to estimate the quantity of ground water that could be withdrawn from the aquifer within the study area. The model was calibrated to match water levels measured in area wells in 1994 and to match the baseflow gains and losses in the Mackinaw River and Sugar Creek. A hypothetical well field, pumping 15 million gallons a day (mgd), was simulated at four locations, The results varied from a maximum drawdown of 8 feet in the Hopedale scenario to 55 feet in the Armington scenario. If a well field similar to the well fields modeled were installed in the study area, as many as 400 private wells may be impacted.
