State of Illinois Drought Preparedness and Response Plan - Adopted by the State Water Plan Task Force, October 12, 2011
The goal of Illinois' Drought Preparedness and Response Plan is to assist community and state officials and the public with information and tools that promote better decision-making in water supply planning and reduce drought-related impacts, water competition, and conflicts of use.
System Information & Drought Vulnerability of Illinois' Community Surface Water Systems - An assessment of the potential impact of severe drought conditions on
Illinois community water supplies, primarily based on the estimation of the water yield provided by each community’s surface water supply sources.
Links with a community name (i.e. Altamont) will provide system information. The associated "vulnerability" link will provide that system's drought vulnerability classification.
A Notes and Terminology area contains information on Drought Vulnerability Classification, Source Types, and more.

Illinois Water Supply (Illinois State Water Survey) - What is water? This may seem a simple question, but have you thought about how many different uses exist for water? Each day in Illinois, water is used for drinking, bathing, and washing our dishes - but it is also used for navigation, in industry, and as a source of power. Illinois is a water-rich state, but water availability varies widely across the State. The Illinois State Water Survey has answered some basic questions about water supply and availability in Illinois.

The Water Cycle and Water
Budgets in Illinois: A Framework for Drought and Water-Supply Planning - Provision of adequate and reliable supplies of clean water at reasonable cost is a basic
necessity for public health, the economy, recreation, and navigation. It is the goal of watersupply
planning and management. As water withdrawals increase, so too does the need to protect
watersheds, aquifers, and aquatic ecosystems for present and future generations. With sound
planning and management, there is no reason why the residents of Illinois, a water-rich state,
ever should face a water crisis. Without sound planning and management, however, current local
problems and regional concerns could mushroom into conflicts and crises, and courts increasingly
could be called upon to determine the reasonableness of withdrawals.

Drought Conditions in Illinois - A major study of Illinois droughts
was conducted to develop a basis for quantitative assessments of
drought conditions in Illinois. Such information should aid decision
making related to local and state actions to ameliorate the effects
of future droughts. Those who must deal directly with aspects of
drought need to know 1) whether a drought is developing, 2) how
severe the drought is at any given time, and 3) how long the drought
will last. This report provides information to help address those
