701:		Title:	Rainfall Frequency Atlas of the Midwest
		Volume/Number:	71
		Issuing Agency:
		Description:	This report presents the results and methodology of an intense study of rainfall frequency relationships throughout the Midwest (Illinois, Indiana, Iowa, Kentucky, Michigan, Minnesota, Missouri, Ohio, and Wisconsin). Using primarily 275 long-term daily reporting stations from the National Weather Service cooperative network supplemented by 134 daily reporting stations with shorter records, rainfall amounts have been determined for recurrence intervals from 2 months to 100 years and for durations of 5 minutes to 10 days. The results are presented as maps and as climate division averages in tabular form. Several special raingage networks were used to develop relationships between amounts for 24 hours and less. This report also examines the time distributions of heavy rainfall over time, and other storm characteristics such as storm orientation and movement. The assumption of spatially independent observations between stations also is discussed.

702:		Title:	Climate Fluctuations in Illinois, 1901-1980
		Volume/Number:
		Issuing Agency:
		Description:	Changes in climate directly affect four areas of major ctivity and concern in Illinois water, energy, agriculture, and transportation. This report presents selected Illinois records for 1901-1980 on a variety of atmospheric conditions that allow assessment of climate fluctuations, climate trends, variability around the trends, and impacts of these changes on the four areas of concern. Documented are changes in statewide and regional precipitation and temperature, plus selected point (station) data. Also presented are changes in other atmospheric conditions including relative humidity, sky cover and sunshine, visibility and related air quality smoke/haze/dust), severe local storms, and wind speed and direction. The historical records are carefully evaluated as to quality. Analyses of the data indicate changes in the more recent 20 years (1961-1980 compared with 1901-1960) to wetter and cooler conditions: more rain and snow and fewer droughts; decreases in temperatures especially in summer and winter, with fewer extremely warm days and many more extremely cold days; increases in cloudiness and decreases in sunshine and clear days especially in summer; and increases in wind speeds with more diverse wind directions. All trends are more marked in the extreme seasons of summer and winter than in the transition seasons of spring and fall, although somewhat warmer springs have produced a slightly longer growing season in the recent period. Mixed regional changes are noted in other atmospheric conditions, and no trend is apparent for relative humidity.

705:		Title:	The mineral content of Illinois waters
		Volume/Number:	1908
		Issuing Agency:
		Description:	The State Water Survey of Illinois began the investigation of the waters of the State in 1895. While the Survey has laid special stress on the determination of the character of the waters from a sanitary standpoint, it has also often been called upon to make analyses of the mineral content to determine its character from a medicinal or commercial standpoint. In the various reports so far issued by the Survey only results of the sanitary investigations were published. It had been the intention to publish the results of the mineral analyses in a previous report but this had to be postponed until the present time when, in cooperation with the Geological Survey, it has become possible. This Bulletin, primarily, contains the records of the analyses made to determine the composition of the mineral residue with reference to the value of the water for manufacturing and medicinal uses, but there are also included the sanitary analyses, wherever such analyses have been made.

706:		Title:	Municipal water supplies of Illinois
		Volume/Number:	1908
		Issuing Agency:
		Description:	For more than ten years the State Water Survey has been making analyses of the various waters used by the people of the State. The work has been carried on in accordance with an Act of the Fortieth General Assembly entitled An Act to establish a chemical survey of the waters of the State of Illinois." This report contains data concerning the source of the water supplies and the quality of the water of cities which according to the census of 1900 had more than 1,000 inhabitants. The data concerning the supplies was obtained by correspondence with water works officials or city officers. Three series of letters were sent out and a direct-report, more or less complete, has been received from all but fourteen of the cities having more than 1,000 inhabitants. In a few instances data have been taken from previous works which treat of the municipal water supplies of Illinois. In nearly every case we have confirmed the data thus taken. There are also included analytical data which have been obtained by the survey since its foundation in 1897 to the end of 1906.

715:		Title:	Selected analytical methods for well and aquifer evaluation
		Volume/Number:	1962
		Issuing Agency:
		Description:	The practical application of selected analytical methods to well and aquifer evaluation problems in Illinois is described in this report. The subject matter includes formulas and methods used to quantitatively appraise the geohydrologic parameters affecting the water-yielding capacity of wells and aquifers and formulas and methods used to quantitatively appraise the response of wells and aquifers to heavy pumping. Numerous illustrative examples of analyses based on actual field data are presented. The aquifer test is one of the most useful tools available to hydrologists. Analysis of aquifer test data to determine the hydraulic properties of aquifers and confining beds under nonleaky artesian, leaky artesian, water table, partial penetration, and geohydrologic boundary conditions is discussed and limitations of various methods of analysis are reviewed. Hydraulic properties also are estimated with specific-capacity data and maps of the water table or piezometric surface. The role of individual units of multiunit aquifers is appraised by statistical analysis of specific capacity data. The influence of geohydrologic boundaries on the yields of wells and aquifers is determined by means of the image-well theory. The image-well theory is applied to multiple boundary conditions by taking into consideration successive reflections on the boundaries. Several methods for evaluating recharge rates involving flow-net analysis and hydrologic and groundwater budgets are described in detail. Well loss in production wells is appraised with step-drawdown test data, and well screens and artificial packs are designed based on the mechanical analysis of the aquifer. Optimum well spacings are estimated taking into consideration aquifer characteristics and economics. Emphasis is placed on the quantitative evaluation of the practical sustained yields of wells and aquifers by available analytical methods. The actual groundwater condition is simulated by a model aquifer having straight-line boundaries, an effective width, length, and thickness, and sometimes a confining bed with an effective thickness. The hydraulic properties of the model aquifer and its confining bed, if present, the image-well theory, and appropriate groundwater formulas are used to construct a mathematical model that provides a means of evaluating the performance of wells and aquifers. Records of past pumpage and water levels establish the validity of this mechanism as a model of the response of an aquifer to heavy pumping.

718:		Title:	Chemical survey of the waters of Illinois: report for the years 1897-1902
		Volume/Number:	1903
		Issuing Agency:
		Description:	SIR: Herewith I submit a report of the work of the Chemical Survey of the Water Supplies of Illinois, covering the years 1897 to 1902, inclusive. As was stated in my preliminary report, published in 1897, portions of which are incorporated in the present report, the aims of the survey include the determination of the present sanitary condition of the water supplies drawn from the lakes, the streams, and the wells of the State; the determination of the normal condition of uncontaminated waters; the formulation of local standards of purity based upon the results of analyses of water derived from unpolluted sources; the provision of such means as shall afford to citizens of the State opportunity to obtain immediate information regarding the wholesomeness of the potable waters in which they are directly interested; and in general the prevention of the development and dissemination of disease from the use of impure water. The press of work in certain of these directions has been so great that comparatively little has been accomplished in others, and a mass of data concerning the normal condition of ground waters must be left for digestion and discussion at some future time. The present report may be broadly divided into three parts, namely: 1. A brief consideration of the sanitary condition of the ordinary ground waters and matters relating thereto. Accompanying this there is a paper upon 'The Geology of Illinois as Related to Water Supplies,' by Charles W. Rolfe, Professor of Geology in the University. 2. Results of the mineral analysis of some four hundred and sixty samples of water mainly from wells of considerable depth. 3. A report of the investigation of the surface waters of the State, relating chiefly to the Illinois River and some of its tributaries. Most of the routine work of these investigations has been conducted by Mr. C. V. Millar, M. S., and Mr. R. W. Stark, B. S., to whom special commendation is due for the continued interest, the skill and the unfailing zeal with which they have furthered the purposes of the Survey. At various times we have further been ably assisted by Mr. F. C. Koch, M. S.; Mr. E. P. Walters, B. S.; Mr. A. D. Emmett, B. S.; and Mr. A. L. Marsh. Respectfully submitted, ARTHUR W. PALMER, Sc . D., Professor of Chemistry.

		Volume/Number:	1971
		Issuing Agency:
		Description:	This report presents the climatology of Illinois tornadoes based on data from the 1916-1969 period, and offers a variety of general interest tornado facts. 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.
