Cahokia Creek/Holiday Shores Lake watershed TMDL Report (2007, August) [IEPA/BOW/07-019]
This report documents the analysis and findings of the TMDL development for water segments within this watershed. Illinois is required to identify water bodies that do not meet water quality standards and to determine the Total Maximum Daily Load for pollutants causing the impairment.
Database for the chemical and isotopic composition of the Illinois River Basin, Illinois (2003-2005) [OFS 2009-3]
This report presents the data obtained during a two-year investigation of dissolved constituents in the Illinois River. The objective of the investigation was to identify the major sources of nitrate, chloride and other inorganic constituents present in the Illinois River Watershed from the Chicago area to its confluence with the Mississippi River.
Environmental Education Resources for Teachers
Environmental education covers a broad range of topics from recycling and pollution to natural resources and wildlife. Environmental education programs target all ages from preschool children to graduate students. This guide focuses on resources for teaching K-12 students about the environmental effects of pollution and waste and strategies for improving the environment. It also includes some industrial chemistry resources. This reference guide includes links to classroom activities, background and policy information, standards, and reference sources that teachers can use to develop their own environmental education lesson plans. Because the scope of the topic is so broad, this is not meant to be an exhaustive list. Rather, it is designed to give you some places to start looking for resources. Information to help you continue your research at your local library is included at the end of the guide.
Evergreen Lake watershed TMDL report (2006, December) [IEPA/BOW/07-001]
This report documents the analysis and findings of the TMDL development for water segments within this watershed. Illinois is required to identify water bodies that do not meet water quality standards and to determine the Total Maximum Daily Load for pollutants causing the impairment.
Geology of the Mackinaw River watershed, McLean, Woodford, and Tazewell Counties, Illinois (2009) [Field Trip Guidebook 2009-A]
Geological Science Field Trip to the north-central part of the Illinois Basin, in the Mackinaw River watershed.
Hodges Creek watershed TMDL report (2006, November) [IEPA/BOW/07-002]
This report documents the analysis and findings of TMDL development for water segments within this watershed. Illinois is required to identify water bodies that do not meet water quality standards and to determine the Total Maximum Daily Load for pollutants causing the impairment.
Hydrologic Model of the Vermilion River Watershed for Streamflow Simulations [2004-10]
In continuation of the efforts made by the Illinois State Water Survey to develop a detailed hydrologic and water quality simulation model of the entire Illinois River Basin, a hydrologic simulation model was developed for the Vermilion River Watershed (one of the major tributaries of the Illinois River) to simulate streamflows using available climatic data. The model was developed using Hydrologic Simulation Program FORTRAN (HSPF, version 12) under the BASINS (Better Assessment Science Integrating Point and Nonpoint Sources, version 3.0), a multipurpose environmental analysis system developed by the U.S. Environmental Protection Agency (USEPA).
Hydrologic Modeling of Climate Scenarios for Two Illinois Watersheds [2004-07]
Watershed modeling applications for the Fox and Iroquois River watersheds in Illinois were used to evaluate the response in simulated streamflow to various climate scenarios. The climate scenarios applied to both watersheds are based on simulations from two global climate models, the Japan and Hadley models, which respectively represent comparatively dry and wet scenarios of future climatic conditions.
Hydrologic Modeling of the Iroquois River Watershed Using HSPF and SWAT [2004-08]
Watershed scale hydrologic simulation models HSPF (Hydrologic Simulation Program FORTRAN) and SWAT (Soil and Water Assessment Tool) were used to model the hydrology of the 2150 square mile Iroquois River watershed (IRW) located in the east central Illinois.
