Illinois ranks eighth nationally in the number of tornadoes, but first in deaths and second in tornado damages. On the average, there are 10 tornadoes per year, occurring on five days. The annual average death rate from these storms is slightly over 19with an injured average of 110 people. A majority (65 percent) of Illinois tornadoes occur during March through June, with 15-21 April being the prime 7-day period. Over 40 percent occur between 1500 and 1800 CST, and 65 percent take place from 1400-2000 CST. Five of the outstanding Illinois tornado days of the 1916-1969 period are discussed in detail, including the famed Tri-State tornado of 18 March 1925, the most devastating tornado in the United States since systematic collection of tornado data began in 1916.The general information includes, among other items, basic definitions pertinent to tornadoes, safety precautions, formulation of a tornado forecast, and methods for remote detection of tornadoes. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-103 | | | | ISL ID: | 000000000738 Original UID: 999999993755 FIRST WORD: Illinois | |

| 1073: | | Title: | | | | | Volume/Number: | 1925 | | | | Issuing Agency: | | | | | Description: | GENTLEMEN : Herewith I submit a report on the ground water resources of the State of Illinois and recommend that it be published as Bulletin No. 21. Since the Directors' report includes a statement of the general activities of all divisions, it has seemed advisable to discontinue the publication of an annual report of this division and to prepare instead summaries of our various investigations as they are completed. This policy was adopted with the publication of Bulletin No. 18 in May of 1922, and has been followed since that date. A portion of this material has appeared in abstract form in annual reports published prior to 1920. That material was too meager and scattered to be of practical value. In the present collected form we believe this data will be of very considerable value to the State of Illinois. Respectfully submitted, A. M. BUSWELL, Chief. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | B-21 | | | | ISL ID: | 000000000758 Original UID: 999999992021 FIRST WORD: Public | |

This report is essentially a solar data compendium for Illinois. It contains a minimum of text and consists mainly of tables and graphs, largely assembled from a wide variety of publications (many not easily found). | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-133 | | | | ISL ID: | 000000000759 Original UID: 999999993789 FIRST WORD: Solar | |
| 1075: | | Title: | | | | | Volume/Number: | 1981 | | | | Issuing Agency: | | | | | Description: | Because of its responsibility for allocating the Lake Michigan water which Illinois is permitted to divert from the Great Lakes Basin, the Illinois Division of Water Resources must consider alternative sources of water available to the Chicago metropolitan region. In early 1979, the Division contracted with the Illinois State Water Survey to study the shallow dolomite aquifer in DuPage County, an important alternative source, to verify its potential yield. The plan of the investigation was to analyze the effects of continually increasing pumpage, and to identify areas of existing and potential problems and areas where additional pumpage can be developed. In the summer of 1979, as part of this study, a detailed data collection program in the shallow dolomite was conducted over a 700-square-mile area, shown in figure 1. The area centered on DuPage County but also included parts of west and northwest Cook County, east Kane County, northeast Kendall County, and north Will County. It was bounded on the west by the Fox River and on the east and southeast by the Des Plaines River. Data obtained included pumpage from major water users and more than 1200 water level measurements. In addition, 282 water samples were collected for subsequent analysis. | | | | Date Created: | 5 18 2005 | | | | Agency ID: | C-149 | | | | ISL ID: | 000000000760 Original UID: 999999993807 FIRST WORD: Verification | |
| 1076: | | Title: | | | | | Volume/Number: | 1987 | | | | Issuing Agency: | | | | | Description: | 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 questions. The report draws upon relevant results of in-depth studies of most critical aspects of drought, including the ways drought is reflected in the major components of the hydrologic cycle. Procedures are given for assessing drought presence and severity in terms of precipitation conditions, soil moisture conditions, shallow groundwater levels, and streamflows. Routine monitoring of these four conditions, coupled with the use of relationships developed in the drought study, serves to detect the onset of droughts in Illinois. Methods for determining the end of drought are not perfect, but the report discusses means by which the termination of drought can be estimated. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-169 | | | | ISL ID: | 000000000761 Original UID: 999999993827 FIRST WORD: Detecting | |
| 1077: | | Title: | | | | | Volume/Number: | 1989 | | | | Issuing Agency: | | | | | Description: | This publication represents a condensed version of an extensive report on the distributions of heavy rainstorms in Illinois, based on data for 61 precipitation stations operated during 1901-1983. Shown are annual frequency distributions of point rainfall for periods ranging from 5 minutes to 10 days and for recurrence intervals varying from 2 months to 100 years. Results are presented in two forms: mean relations for ten regions of approximately homogeneous precipitation climate, and statewide isohyetal maps based on the 61-station data The report also discusses the results of a special investigation pertaining to Chicago and the surrounding six counties subject to urban influences on the precipitation distribution. The final section of the report provides information on the urban influences on the two Illinois counties adjacent to St. Louis. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-172 | | | | ISL ID: | 000000000762 Original UID: 999999993832 FIRST WORD: Frequency | |
| 1078: | | Title: | | | | | Volume/Number: | 1990 | | | | Issuing Agency: | | | | | Description: | This document provides the best available in formation on the time-distribution characteristics of heavy rainstorms at a point and on small basins in Illinois and the Midwest. It is recommended for use in conjunction with Illinois State Water Survey Bulletin 70 and Circular 172 for runoff computations related to the design and operation of runoff control structures. It is also useful for post-storm assessment of individual storm events in weather modification operations. Information is presented in the form of families of curves derived for groups of storms categorized according to whether the greatest percentage of total storm rainfall occurred in the first, second, third, or fourth quarter of the storm period. The time distributions are expressed as cumulative percentages of storm rainfall and storm duration to enable comparisons between storms. The individual curves for each storm type provide estimates of the time-distribution characteristics at probability levels ranging from 10% to 90% of the total storm occurrences. Explanations are provided of how to use the results in design problems. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-173 | | | | ISL ID: | 000000000763 Original UID: 999999993833 FIRST WORD: Time | |
| 1079: | | Title: | | | | | Volume/Number: | 1993 | | | | Issuing Agency: | | | | | Description: | This document provides pertinent information on the spatial distribution characteristics of extremely heavy rainstorm events in Illinois and the Midwest. Relations were developed for those storms in which maximum rainfall at the center equaled or exceeded the point maximum experienced on the average of once in 100 years or longer. The study was limited to this group of storms because of existing needs for information on these extreme storm events in the design and operation of water control structures in small basins. It is recommended for use in conjunction with Illinois State Water Survey Bulletin 70, Bulletin 71 (Midwestern Climate Center Research Report 92-03), and Water Survey Circular 173 for runoff computations related to the design and operation of runoff control structures in small basins subject to extreme rainfall events. Area-depth relations were derived from information obtained through operation of several dense raingage networks, detailed field surveys and analyses of severe rainstorms in Illinois, analyses of heavy rainstorms in a six-basin hydroclimatic study, and exceptional storms recorded by the climate network of the National Weather Service in Illinois. Using data and information from these sources, curves defining spatial distributions for storms of various areal extent were derived. Results are presented in a form readily adaptable for use by hydrologists or other interested users. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-176 | | | | ISL ID: | 000000000764 Original UID: 999999993836 FIRST WORD: 100 | |
| 1080: | | Title: | | | | | Volume/Number: | 1994 | | | | Issuing Agency: | | | | | Description: | The Illinois Climate Network (ICN) consists of 19 automated weather stations operated by the Illinois State Water Survey. Stations are located on the University of Illinois Agricultural Experiment Station Farms, the Southern Illinois University Agronomy Experiment Farms, and on community college campuses around the state. The ICN is part of the Water and Atmospheric Resources Monitoring (WARM) Network, which also collects information on soil moisture, groundwater, surface water, and suspended stream sediments. The ICN data have been used for agricultural purposes, such as for irrigation scheduling and to evaluate the progress of insect and crop development during spring and summer. The Illinois Department of Agriculture frequently requests the wind data when evaluating spray drift complaints. The ICN data are also used to assess the potential for using solar radiation and wind as alternative energy sources in Illinois. At each station a 10 meter tower equipped with weather instruments records hourly average air temperature, relative humidity, solar radiation, wind speed and direction, barometric pressure, and soil temperatures at 10 and 20 centimeters. Detailed descriptions of station sites are presented, including areal photographs of a 1,000 meter radius of each station. Hourly wind speed mean and variances were used to estimate the effect of obstructions around the weather towers on wind flow at each tower. Total hourly precipitation and hourly standard deviations of each weather variable are also recorded. The barometric pressure, including hourly maximum and minimum pressures and the time of the maxima and minima, have been recorded since early 1992. Daily data that are saved include maximum and minimum air temperature, maximum and minimum relative humidity, maximum and minimum soil temperatures, maximum wind gusts and direction, and their times of occurrence. The data are automatically retrieved from the stations once each day between midnight and 4:00 a.m. At least three times a week, a database management technician checks the data for quality control, and then the data are made available to the public on the Midwestern Climate Center's Midwestern Climate Information System. | | | | Date Created: | 9 24 2004 | | | | Agency ID: | C-178 | | | | ISL ID: | 000000000765 Original UID: 999999993838 FIRST WORD: Illinois | |
