Flooding in Illinois, April-June 2002

Widespread flooding occurred throughout most of Illinois in spring 2002 as a result of multiple intense rainstorms that moved through the State during an extended 2-month period from the third week in April through the month of May in central and southern Illinois, the first week in June in northern Illinois, and the second week in June in west-central Illinois. The scale of flooding was highly variable in time and intensity throughout the State. A Federal disaster was declared for central and southern Illinois to deal with the extensive damage incurred during the severe weather, and to provide emergency aid relief. Discharge and stage records for the flood periods described above are presented for 193 streamflow-gaging stations throughout Illinois and in drainages just upstream of the State. New maximum instantaneous discharge was recorded at 12 stations during this flood period, and new maximum stage was recorded at 15 stations. Flood stage was exceeded for at least 1 day during this 2-month period at 67 of the 82 stations with established flood-stage elevations given by the National Weather Service. Of the 162 streamflowgaging stations with an established flood-frequency distribution, a 5-year or greater flood discharge was recorded at 87 stations, and a 100-year or greater flood discharge occurred at six stations.

Estimated water withdrawals and use in Illinois, 1992

The total amount of water withdrawn in Illinois during 1992 was about 19,076 (Mgal/d) million gallons per day. About 16,101 Mgal/d, or about 84 percent of this total, was withdrawn for thermoelectric-power generation, and about 1,877 Mgal/d was withdrawn by and delivered from public-supply facilities. About 1,910 Mgal/d of surface water was withdrawn, excluding withdrawals for thermoelectric-power generation. Public-supply facilities in Illinois withdrew about 1,210 Mgal/d from Lake Michigan in 1992. The next largest withdrawal of surface water was that by self-supplied industrial users. About 1,068 Mgal/d of the total water withdrawn was ground water; about 25 Mgal/d of this ground water was saline. Public-supply facilities withdrew about 36 percent of the total ground water withdrawn; the second largest withdrawal of ground water was for irrigation.

Reversal of declining ground-water levels in the Chicago area

Abundant water resources have been an important part of the economic development of the Chicago area for more than a century. The city of Chicago, Ill., and other lakefront towns have used Lake Michigan as a water supply. Where water from Lake Michigan was not available or a need for supplemental water supplies was present, deep wells (generally greater than 700 feet) provided a clean, reliable, and abundant water supply from the Cambrian-Ordovician aquifer. Public water suppliers withdraw the most ground water in the eight-county Chicago area (Cook, Du Page, Grundy, Kane, Kendall, Lake, McHenry, and Will Counties). This report describes a reversal in the trend of declining ground-water levels in the Cambrian-Ordovician aquifer in the Chicago area as public water suppliers have converted from the withdrawal of ground water from wells to the withdrawal of surface water from Lake Michigan.

Ground-water hydrology of Ogden Valley and surrounding area, eastern Weber County, UT, and simulation of ground-water flow in the Valley-fill aquifer system

The ground-water resources in Ogden Valley, eastern Weber County, Utah, were the subject of a study to provide a better understanding of the hydrologic system in the valley and to estimate the hydrologic effects of future ground-water development. The study area included the drainage basin of the Ogden River upstream from Pineview Reservoir dam and the drainage basin of Wheeler Creek. Ogden Valley and the surrounding area are underlain by rocks that range in age from Precambrian to Quaternary. The consolidated rocks that transmit and yield the most water in the area surrounding Ogden Valley are the Paleozoic carbonate rocks and the Wasatch Formation of Tertiary age. Much of the recharge to the consolidated rocks is from snowmelt that infiltrates the Wasatch Formation, which underlies a large part of the study area. Discharge from the consolidated rocks is by streams, evapotranspiration, springs, subsurface outflow, and pumping from wells. Water in the consolidated rocks is a calcium bicarbonate type and has a dissolved-solids concentration of less than 250 milligrams per liter.

Seepage studies of the Weber River and the Davis-Weber and Ogden Valley canals Davis and Weber Counties, Utah, 1985

Studies of selected reaches of the Weber River, Davis-Weber Canal, and the Ogden Valley Canal in Davis and Weber Counties, Utah, were made to determine gains or losses of flow in those reaches. Three to five sets of seepage measurements were made on the river and each canal during 1985. Adjustments for fluctuations in flow were made from information obtained from water-stage recorders operated at selected locations during the time of each set of seepage measurements. The studies indicated a loss of 20.0 cubic feet per second in the upstream reach of the Weber River and a gain of 17.0 cubic feet per second in the downstream reaches or a net loss of 3.0 cubic feet per second. Study results also indicated a net loss of 17.0 cubic feet per second in the Davis-Weber Canal and a net loss of 4.0 cubic feet per second in the Ogden Valley Canal.

Bedrock aquifers of eastern San Juan County, Utah

This study is one of a series of studies appraising the waterbearing properties of the Navajo Sandstone and associated formations in southern Utah. The stu<¥ area is al:x>dy area is about 4,600 square miles, extending from the Utah-Arizona State line northward to the San Juan-Grand County line and westward from the Utah-Colorado State line to the longitude of about 109°50'. Some of the water-yielding formations are grouped into aquifer systems. The C aquifer is comprised of the DeChelly Sandstone Member of the Cutler Formation. The P aquifer is comprised of the Cedar Mesa Member of the Cutler Formation and the undifferentiated Cutler Formation. The N aquifer is comprised of the sedimentary section that includes the Wingate Sandstone, Kayenta Formation, Navajo Sandstone, Carmel Formation, and Entrada sandstone. The M aquifer is comprised of the Bluff Sandstone Member and other sandstone units of the Morrison Formation. The D aquifer is comprised of the Burro Canyon Formation and Dakota Sandstone. Discharge from the ground-water reservoir to the San Juan River between gaging stations at Four Corners and Mexican Hat is about 66 cubic feet per second. The N aquifer is the main aquifer in the study area. Recharge by infiltration of precipitation is estimated to be 25,000 acre-feet per year. A major ground-water divide exists under the broad area east of Monticello. The thickness of the N aquifer, where the sedimentary section is fully preserved and saturated, generally is 750 to 1,250 feet. Hydraulic conductivity values obtained from aquifer tests range from 0.02 to 0.34 foot per day. The total volume of water in transient storage is about 11 million acre-feet. Well discharge somewhat exceeded 2,340 acre-feet during 1981. Discharge to the San Juan River from the N aquifer is estimated to be 6.9 cubic feet per second. Water quality ranges from a calcium bicarbonate to sodium chloride type water

Developing a state water plan: Ground-water conditions in Utah, spring of 1984

This is the twenty-first in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions. This report, like the others in the series, contains information on well construction, ground-water withdrawals from wells, water-level changes, and related changes in precipitation and streamflow. Supplementary data such as graphs showing chemical quality of water and maps showing ground-water level contours are included in reports of this series only for those years or areas for which applicable data are available and are important to a discussion of changing ground-water conditions. This report includes individual discussions of selected major areas of ground-water development in the State for the calendar year 1983. Water-level fluctuations, however, are described from the spring of 1983 to the spring of 1984. Much of the data used in this report were collected by the U.S. Geological Survey in cooperation with the Division of Water Rights, Utah Department of Natural Resources.
