The water resources of southeast Iowa

Water is vital in the lives of the people and the economy of any area. In order to utilize this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of its sources and the occurrence and potential of each source must be gained. To provide this knowledge, the Water Resources Division of the U.S. Geological Survey in cooperation with the Iowa Geological Survey compiled this atlas describing the water resources available for development in an 11-county area in southeast Iowa. The report contains information on the availability, quality, and utilization of water from all known sources and the future demands upon the water resources in southeast Iowa. The information is presented to aid water users and other persons searching for and evaluating sources of water in a particular place, and planners and water managers who must consider water resources on a regional basis.

Water resources of east-central Iowa

Water is vital in the lives of the people and the economy of any area. To utilize this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of its sources and the occurrence and potential of each source must be gained. To provide this knowledge, the Water Resources Division of the U.S. Geological Survey in cooperation with the Iowa Geological Survey compiled this atlas describing the water resources available for development in an 12-county area in east-central Iowa. The report contains information on the availability, quality, and utilization of water from all known sources and the future demands upon the water resources in east-central Iowa. The information is presented to aid water users and other persons searching for and evaluating sources of water in a particular place, and planners and water managers who must consider water resources on a regional basis.

Water resources of north-central Iowa

One of man's fundamental needs is water. Modern man needs both a safe and dependable supply of water to maintain his present economic, industrial, and cultural level. In order to use this natural resource in the most efficient and beneficial manner, a basic knowledge and understanding of water sources, and of the occurrence and potential of each source, needs to be gained. To provide this information, the U.S. Geological Survey, in cooperation with the Iowa Geological Survey, has compiled this atlas. It describes the water resources available for development in an 11-county area in north-central Iowa. The report contains information on the quantity, quality, and use of water from all known sources of water. This information is presented to aid water users and developers who are searching for and evaluating sources of water for specific sites. It also will be an aid to water planners and managers who must develop the available water resources on a regional basis.

Water resources of south-central Iowa

The objective of this report is to present information on the water resources of south-central Iowa that will help solve the supply problems of the water users in the region and that will aid planners and water managers who must consider water resources on a regional basis. The information presented includes the availability, quality, and utilization of water from all known sources and the future demands upon the water resources.

The water story in Central Iowa

"The general welfare of the people of the state of Iowa requires that the water resources of the state be put to beneficial use to the fullest extent of which they are capable." This can be achieved only by a knowledge and understanding of the water resources - their use, their source, their quality, their availability, and the demands place upon them. To provide such knowledge and understanding, the United States Geological Survey in cooperation with the Iowa Geological Survey produced this report on the utilization and availability of water in central Iowa. This report contains information on the past, present, and future statues of central Iowa;s water; information that can be used by the regional developer, the resource planner and manager, and other informed persons whose opinions and sound judgements are required in making decisions toward efficient development, management, use, and conservation of water. It gives an over-all view of the area's water resources and is aimed at guiding the people of central Iowa to the best available sources of water.

Availability of ground water in Decatur County, Iowa

Decatur County and several other counties in south-central Iowa comprise an area that has been chronically short of good-quality water. Municipalities, industries and rural water users alike have been affected by the water shortage. Municipalities have experienced serious problems in obtaining potable supplies adequate to keep pace with their growth and development: industrial expansion has been hindered and continues to be hindered by the shortage of good-quality water; and rural supplies for domestic and livestock use are difficult to obtain at many places. The increased use of water for all purposes and periodic drought conditions have greatly magnified an already serious problem of water shortage.

Water resources of northeast Iowa

In 1965 a cooperative investigation with the U.S. Geological Survey produced Water Atlas No. 1 (Twenter and Coble, 1965). It presented information on the occurrence, availability, use, quality, and future demand of water in 10 counties in the central part of the state. Subsequent investigations produced Water Atlases No. 4 (Coble and Roberts, 1971) for southeast Iowa, No. 5 (Cagle and Heinitz, 1978) for south-central Iowa, No. 6 (Wahl et al., 1978) for east-central Iowa, and No. 7 (Buchmiller et al., 1985) for north-central Iowa. The present study, Water Atlas No. 8 (1989), describes the surface-water and groundwater resources of 11 counties in extreme northeast Iowa. With the publication of this report, water atlases are now available for the eastern two-thirds of the state.

Delineation of flooding within the upper Mississippi River Basin, 1993 — Flood of June 29-September 18, 1993, in Iowa City and vicinity, Iowa

The hydrologic investigations atlas shows the areas in and around Iowa City, Iowa, that were flooded by the Iowa River in 1993. This map also depicts the Federal Emergency Management Agency (FEMA) 100-year flood boundaries. The drainage basin of the Iowa River at Iowa City received well over 100 percent of normal rainfall in June, July, and August, 1993. At the Cedar Rapids airport, located about 20 miles north-northwest of Iowa City, July rainfall was 414 percent of normal. The discharges at U.S. Geological Survey streamflow-gaging stations on the Iowa River upstream of Coralville Reservoir, just downstream from Coralville Reservoir, and at Iowa City are shown. A profile of the maximum water-surface elevations of the 1993 flood in Iowa City and vicinity is higher than the FEMA 100-year flood profile. The water-surface elevation of Coralville Reservoir is shown from June 29-September 18, 1993.

Jordan aquifer of Iowa

Water demand for all uses in Iowa is increasing at an accelerated rate. Demand has increased from about 1,800 million gallons per day in 1955 to 3,500 million gallons per day in 1975 (MacKichan, 1957; Murray and Reeves, 1977). By the year 2020, water demand is expected to be eight times that in 1975 (Barnard and Dent, 1976). Historically, about 75 percent of the demand, excluding that required for power generation, has been met by withdrawals from the water-bearing zones (aquifers) in Iowa's ground-water reservoir. Because this percentage is expected to remain about the same, the anticipated future demands will require extensive withdrawals from the ground-water reservoir. The increasing stress on the ground-water system, which already is severely stressed in several places in the state, will create development and management problems that will require hydrologic information to solve. In order to provide this information, the lowa Geological Survey in cooperation with the U.S. Geological Survey has instituted a series of investigations to define, describe, and evaluate the major aquifers in Iowa's groundwater reservoir. Information from each investigation will be presented in atlas format.
