Researching Water Use
Great Lakes Regional Water Use Database
This database offers customized searches of water use. Covers all great lakes and surrounding states, including Illinois, for 1998 - 2008, by category of use. Search Great Lakes Surface Water withdrawals as well as uses of other water supplies, including groundwater, and download as a spreadsheet.
USGS: National Water Use Information
The USGS cooperates with local, State, and Federal environmental agencies to collect water-use information. USGS compiles these data to produce water-use information aggregated at the county, state, and national levels. Includes comparative analyses by water-use region.
Illinois Dept. of Natural Resources
Loads of information, such as a current flood map, a river stage summary table, USGS real-time precipitation data, flood surveillance, Lake Michigan water allocation tables, and more.
CMAP Studies and Reports
Water 2050: Regional Water Supply/ Demand Plan
CMAP's Executive Summary provides an outline of the Water Plan and summarizes some of its major focus areas and recommendations: the methodology for determining regional water demands and supplies, the importance of integrating land-use and water supply planning, and demand management and other water-saving strategies.
Regional Water Demand Scenarios, 2005-2050
Conducted by SIU Carbondale on behalf of CMAP, this study reveals important consequences of population growth for the region by the year 2050. It generates three water demand scenarios by major water user sectors and geographical subareas within the region. The scenarios represent water withdrawals under a current trends or "baseline" scenario (CT scenario) as well as under a less resource intensive (LRI) scenario and a more resource intensive (MRI) scenario. While the CT scenario assumes a continuation of recent trends for the variables modeled, resulting in a 36% overall increase in water withdrawals by 2050, the region's public water supply needs could grow up to 55 percent by 2050 under the MRI scenario.
Estimating Water use Effects of Infill Growth vs. Exurban Expansion
This report aimed to determine the water-demand effects that would result from geographically differential patterns of population growth associated with different types of housing within the 11-county study area in Northeastern Illinois- but was unsuccessful due to the aggregated nature of the water-use data.
Full-Cost Water Pricing Guidebook for Sustainable Community Systems
An expert-reviewed manual that explores full-cost pricing as a tool for local decision makers interested in sustainably managing community water supply.
USDA/ National Agriculture Library
NAL Dynamic Bibliographies
Dynamic bibliographies on benchmark watersheds, CEAP studies, and more. Dynamic bibliographies can contain topic-related results from any searchable source. The term "dynamic" refers to the fact that a new bibliography is generated each time you use the link, so the bibliography's citations are always up-to-date.
NAL: Wetlands Research
A clearinghouse for bibliographies, treaties (such as the Ramsar Convention), and websites (such as one on hydric soils) dealing with wetlands.

The Illinois Water and Related Well Data Web mapping project enables on-line access to a large database of over 275,000 Illinois water and related well records. This database has been in development for many years by the Illinois State Geological Survey. Layers include bedrock topography, aquifers, karst areas, and more.
Illinois Water Supply Planning
Maps of shallow gravel, shallow bedrock, and deep bedrock aquifers, their potential yields, well locations, and aquifer recharge. Produced by the Illinois State Water Survey.
Includes information on water, air, land, waste, toxics and radiation, monitoring/remediation programs by category, industries by category, specific chemicals by name. View lists or generate maps for a region, zip code, park, or body of water.

CMAP is the official regional planning organization for the northeastern Illinois counties of Cook, DuPage, Kane, Kendall, Lake, McHenry, and Will. CMAP developed and now guides the implementation of GO TO 2040, metropolitan Chicago's first comprehensive regional plan in more than 100 years. This page links to general information and opportunities.
Great Lakes Restoration Initiative
The Great Lakes Restoration Initiative is the largest investment in the Great Lakes in two decades. A task force of 11 federal agencies has developed an action plan addressing five urgent focus areas:
cleaning up toxics and areas of concern; combatting invasive species; promoting nearshore health by protecting watersheds from polluted run-off; restoring wetlands and other habitats; and working with partners on outreach.
Green Infrastructure for Clean Water Act, Illinois
Public Act 96-26, the Green Infrastructure for Clean Water Act, requires the Illinois EPA to assess and evaluate using green infrastructure to help manage stormwater in Illinois. Illinois EPA is currently working with the University of Illinois – Chicago to undertake research to assess effective best management practices, green infrastructure standards and institutional and policy frameworks to support the development of a Green Infrastructure Plan for Illinois. The site lists contacts for involvement and advocacy.
Safe Drinking Water Act
SDWA was originally passed by Congress in 1974 to protect public health by regulating the nation's public drinking water supply. The law was amended in 1986 and 1996 and requires many actions to protect drinking water and its sources: rivers, lakes, reservoirs, springs, and ground water wells.
