Research Bulletin

Part of: Electronic Documents of Illinois

This Research Bulletin, with the headline Children's Risk of Homicide Victimization Rates for Chicago Children from Birth to Age 14, 1965 to 1995, examines the 1,124 homicides of children aged 14 and younger that occurred in Chicago from 1965 to 1995. Trends in population-based risk of homicide compare the risks for young children versus older teens and adults, boys versus girls, children of different racial/ethnic groups, and children in different developmental age groups. Patterns in these 31-year trends suggest practical implications for reducing homicide levels among young children.

Results of the 2003 Illinois Light Goose Conservation Action Survey

Part of: Electronic Documents of Illinois

Harvest of light geese during the 2003 Illinois Conservation Action was estimated at 30,564 geese, an increase of 12,689 (71%) from the 2002 harvest of 17,875. Participation decreased to 3,111 hunters during 2003 compared to 5,107 hunters during 2002. Hunters spent an estimated 27,177 days afield during 2003, a decrease of 4,027 from the 31,204 days hunted during 2002. Unplugged shotguns were the method used most often (72%); however hunting after sunset and electronic calls were also used by more than 50% of hunters (65% and 63%, respectively). As with hunters responding to the 2002 survey, hunters who did not participate in the conservation action reported no geese in the area and no place to hunt as well as did not have the proper equipment as the main reasons they did not hunt light geese.

Miniature of Sediment and nutrient monitoring at selected watersheds within the Illinois River Watershed for evaluating the effectiveness of the Illinois River Conservation Reserve Enhancement Program (CREP).

Sediment and nutrient monitoring at selected watersheds within the Illinois River Watershed for evaluating the effectiveness of the Illinois River Conservation Reserve Enhancement Program (CREP).

Part of: Electronic Documents of Illinois

This report documents the progress that has been made to date on the Conservation Reserve Enhancement Program (CREP) monitoring project. The Illinois Department of Natural Resources (IDNR) through the CREP provides support for this project. This monitoring program collects hydrologic, sediment, and nutrient data for selected watersheds within the Illinois River watershed to assist in the evaluation of the effectiveness of the program. The Illinois River CREP is a new initiative by the State of Illinois and the United States Department of Agriculture to implement conservation practices in the Illinois River watershed over a 15-year period that improve water quality and habitat for wildlife. Monitoring programs were established for sediment and nutrients for two pairs of watersheds within the Illinois River basin to collect hydrologic, sediment, and nutrient data during the implementation phase of the project. The two pairs of watersheds are the Court and Haw Creek watersheds (Spoon River basin) and the Panther-Cox Creek watershed (Sangamon River basin). This report details the location, equipment, and installation techniques used at the five monitoring stations and associated raingages that were installed as part of the data collection effort for this project. Samples of the data collection format and frequency are presented and described. Stage, nutrient concentration, and suspended sediment concentrations for data collected through June 2000 are also presented as appendices.

Sidestream elevated pool aeration (SEPA) stations: effects on in-stream dissolved oxygen

Part of: Electronic Documents of Illinois

As a result of increased pollutant loading and low in-stream velocities, dissolved oxygen (DO) levels in the Chicago waterways historically have been low. In 1984, the Metropolitan Water Reclamation District of Greater Chicago (MWRDGC) issued a feasibility report on a new concept of artificial aeration referred to as sidestream elevated pool aeration (SEPA). The SEPA station concept involves pumping a portion of water from a stream into an elevated pool. The water is then aerated by flowing over a series of cascades or waterfalls, returning to the stream. The MWRDGC proceeded with design criteria for SEPA stations as a result of experimental work performed by the Illinois State Water Survey (ISWS). Five SEPA stations were constructed and placed in operation along the Calumet River, Little Calumet River, and the Cal-Sag Channel waterway. In 1995 the ISWS returned to conduct research to evaluate the reaeration efficiencies and their effects on in-stream DO. Continuous monitoring of DO, temperature, pH, and conductivity was performed at 14 locations along the Calumet and Little Calumet Rivers, Cal-Sag Channel, and Chicago Sanitary and Ship Canal to evaluate the effectiveness of the SEPA stations on maintaining in-stream DO concentrations. Also, supplemental cross-sectional measurements were made at the 14 locations and at an additional seven locations. Comparisons of mass balance, completely mixed, in-stream mean DO concentrations at the SEPA station outfalls and those measured at cross-sectional stations immediately downstream of each SEPA station were made. Results showed that each SEPA station has an immediate positive impact on in-stream DO concentrations. At SEPA stations 1 and 2, where the impacts are small, the positive effects can best be demonstrated using completely mixed values. Two important conclusions can be made. One is that the SEPA stations, particularly stations 3, 4, and 5, are fulfilling the intended function of maintaining stream DO standards in the Calumet and Little Calumet Rivers and the Cal-Sag Channel. The second is that DO concentrations less than the DO standard are still observed in the Chicago Sanitary and Ship Canal in the reach beginning above its juncture with the Cal-Sag Channel to the Lockport Lock and Dam. Over the entire study period, DO concentrations were maintained above the standard 98.6 percent of the time from the SEPA station 3 outfall to the intake of SEPA station 4 and 97.5 percent of the time from the outfall of SEPA station 4 to the intake of EPA station 5. Significant improvements in DO concentrations were also achieved for at least 4 miles downstream of SEPA station 5 in the Chicago Sanitary and Ship Canal.

Sedimentation survey of Lake Paradise and Lake Mattoon, Mattoon, Illinois

Part of: Electronic Documents of Illinois

The Illinois State Water Survey (ISWS) conducted sedimentation surveys of Lake Paradise and Lake Mattoon during 2001 in support of an Illinois Clean Lakes Program diagnostic/feasibility study to provide information on the storage and sedimentation conditions of the lakes. Both lakes are owned and operated by the City of Mattoon, which withdraws water from Lake Paradise as the raw water source for distribution of finished water and generally uses withdrawals from Lake Mattoon to maintain a more stable water level in Lake Paradise. The village of Neoga also withdraws water from Lake Mattoon for treatment and distribution. Since June 2001, Reliant Energy has operated a peaker power plant that has withdrawn water from Lake Mattoon for cooling systems. Lake Paradise and Lake Mattoon are located on the main stem of the Little Wabash River, a tributary to the Wabash River. The watershed is a portion of Hydrologic Unit 05120114. The dam for Lake Paradise is about 4 miles southwest of the City of Mattoon at 39 24' 47" north latitude and 88 26' 23" west longitude in Section 8, Township 11N., Range 7E., Coles County. The dam for Lake Mattoon is about 12 miles southwest of the City of Mattoon at 39 20' 00" north latitude and 88 28' 56" west longitude in Section 1, Township 10N., Range 6E., Shelby County.Lake Paradise was surveyed in 1979 and Lake Mattoon in 1980 as part of a previous cooperative study by the ISWS, the Illinois Department of Transportation - Division of Water Resources (DoWR), the Illinois Water Resources Center, and several departments at the University of Illinois at Urbana-Champaign. Lake Paradise lost 835 acre-feet (ac-ft) of its capacity as a result of sedimentation between 1908 and 2001. Approximately 481 ac-ft of this loss has occurred since 1931, which gives an annual sedimentation rate of 9.9 ac-ft since 1931. If this rate of sedimentation continues, the volume of Paradise Lake will be approximately half of the potential 1908 volume in the year 2013 and will be filled completely by sediment in the year 2118. Lake Mattoon lost 1,705 ac-ft of its 1958 capacity as a result of sedimentation between 1958 and 2001, a sedimentation rate of 39.7 ac-ft per year since 1958.If this rate of sedimentation continues, the volume of Lake Mattoon will be approximately half of the 1958 capacity by 2124 and will be completely filled in the year 2291. The sedimentation rates for Lake Paradise and its watershed for the periods 1931-1979, 1979-2001, and 1931-2001 were stable and ranged from 9.5 to 10 ac-ft.The long-term average annual sediment yield from 1931-2001 was 9.85 ac-ft. These sedimentation rates correspond to a rate of loss of lake capacity of 0.51 percent per year (1931-2001). The sedimentation rates for Lake Mattoon and its watershed for the periods 1958-1980, 1980-2001, and 1958-2001 indicate a reduction in net sediment yield from 66.9 ac-ft per year for 1958-1980 to 10.7 ac-ft per year (1980-2001).The long-term average annual sediment yield was 39.5 ac-ft (1958-2001). These sedimentation rates correspond to rates of loss of lake capacity of 0.51 percent per year (1958-1980) and 0.08 percent per year (1980-2001).The long-term average sedimentation rate for the lake is 0.30 percent per year (1958-2001).
