Estimated use of water in Nebraska, 1985

The estimated volume of 19,187,200 acre-feet of water used in Nebraska during 1985 is an average of 17,116.15 million gallons per day. Surface water supplied 12,925,040 acre-feet or 67.4 percent of the total volume used. The remaining 6,262,160 acre-feet or 32.6 percent was pumped from the groundwater reservoir. Power production was the greatest use of water of any category, with 10,415,200 acre-feet or 54.3 percent of the total use during 1985. Excluding power production, estimated total water use in Nebraska in 1985 was 7,825.16 million gallots per day, or 8,772,000 acre-feet. Excluding power production, groundwater accounted for 71 percent-or 5,561.51 million gallons per day (6,234,450 acre-feet)-of this total water use in the state in 1985, and surface water accounted for 28.9 percent, or 2,363.65 million gallons per day (2,537,550 acre-feet). Estimated irrigation water use of 8,144,170 acre-feet during 1985 was 42.4 percent of the total water use in the state; excluding power production, it was 92.8 percent of total water use.

Recent investigations of Thiem's method for determining permeability of water‐bearing materials

This paper presents results obtained in an investigation of the ground-water resources of the Platte River Valley that is being conducted in cooperation between the Conservation and Survey Department of the University of Nebraska and the United States Geological Survey. Most quantitative ground-water studies are concerned with the amount of water that percolates into the discharge-area of an investigated region from the recharge-area in order to determine the amount of water that can be safely withdrawn from the discharge-area without an excessive lowering of the ground-water level. D'Arcy found that the quantity of water discharged through a column of water-bearing material was proportional t o the hydraulic gradient, the cross-sectional area, and a constant which depends upon the material. If these three factors are known, the discharge through any cross section of a water-bearing formation may be computed.

The recovery of ground‐water levels in Nebraska in 1935

A program of water‐level measurements in about 350 wells scattered throughout Nebraska was begun in 1934 by the United States Geological Survey in cooperation with the Conservation and Survey Division of the University of Nebraska (see L. K. Wenzel, A state‐wide program of periodic measurements of ground‐water level in Nebraska, Trans. Amer. Geophys. Union, 16th annual meeting, pp. 495–498, 1935). Included in this program were about 60 wells in the Platte River Valley on which periodic measurements were started in 1930. Observations on the 350 wells were continued in 1935 at about monthly intervals and the measurements collected are now being prepared for publication as a paper of the Nebraska Geological Survey.

Several methods of studying fluctuations of ground‐water levels

As a result of increased interest in ground‐water conditions in recent years, records of water‐levels in wells are now being collected in many places in the United States for the primary purpose of determining the relation of precipitation and other natural factors to fluctuations in water‐level. In the past, records of ground‐water levels have been collected chiefly in connection with intensive investigations in areas where the water‐levels were affected by artificial withdrawals and it has not been generally possible to correlate water‐level fluctuations closely with natural factors. It now appears probable that certain methods of studying water‐level fluctuations may be utilized advantageously in areas unaffected by heavy artificial withdrawals, but these methods generally do not yield satisfactory results in areas where there is considerable pumping or artesian flow. Three such methods are presented in this paper. The methods have not been given intensive study and their practical use is therefore not yet fully known. It is hoped that their application will be further investigated. Illustrations of the methods have been taken from records of ground‐water levels in the Platte River Valley, Nebraska, collected by the United States Geological Survey in cooperation with the Conservation and Survey Division of the University of Nebraska.

Specific yield determined from a Thiem's Pumping‐Test

The specific yield of a water-bearing formation is defined as the ratio of (1) the volume of water, which after being saturated, it will yield by gravity to (2) its own volume (O. E. Meinzer, Outline of ground-water hydrology, U.S. Geol. Sur. Water-Supply Paper 494, p. 28, 1923). It is a measure of the quantity of water that a formation will yield when it is drained by lowering of the water-table. The determination of the specific yield is essential in many quantitative ground-water investigations. In 1931 a pumping-test was made in the Platte River Valley, in Nebraska, to determine by Thiem's method the permeability of the water-bearing sand and gravel that underlie the Valley. This test, which constitutes a part of a cooperative investigation by the Conservation and Survey Department of the University of Nebraska and the United States Geological Survey, was briefly described in the 1932 Transactions of the American Geophysical Union (p. 393). The well was pumped continuously for 48 hours, and measurements of the discharge were made every 30 minutes. During the period of pumping and after pumping stopped about 5,000 measurements were made of the depths to the water-surfaces in 80 observation-wells, which were located on lines radiating from the pumped well to distances up to 1,200 feet. Instrumental levels were run to the measuring points on each of the wells so that the altitudes of the water-surfaces could be determined for any time. From the data obtained in this test the average coefficient of permeability was computed to be about 700. In the present paper a method is presented for determining the specific yield of the water-bearing material from the data collected in this test, and the results of the computations are given. This method for determining specific yield was suggested by Meinzer (O. E. Meinzer, Outline of methods for estimating ground-water supplies, U.S. Geol. Sur. water-Supply Paper 638-c, p. 136, 1932).

Validation of national land-cover characteristics data for regional water-quality assessment

Land-cover information is used routinely to support the interpretation of water-quality data. The Prototype 1990 Conterminous US Land Cover Characteristics Data Set, developed primarily from Advanced Very High Resolution Radiometer (AVHRR) data, was made available to the US Geological Survey's National Water-Quality Assessment (NAWQA) Program. The study described in this paper explored the utility of the 1990 national data set for developing quantitative estimates of the areal extent of principal land-cover types within large areal units. Land-cover data were collected in 1993 at 210 sites in the Central Nebraska Basins, one of the NAWQA study units. Median percentage-corn estimates for each sampling stratum wre used to produce areally weighted estimates of the percentage-corn cover for hydrologic units. Comparison of those areal estimates with an independent source of 1992 land-cover data showed good agreement. -Authors

Floods of May-July 1950 in southeastern Nebraska

Four floods occurred in southeast Nebraska during the period of May to July 1950. Two of these were the greatest known in the State if the size of the drainage areas is considered, and the other two were not so spectacular but were of notable size and of possible hydrologic significance in their relation to the two major floods. Although property loss and damage have been exceeded in previous floods in Nebraska, notably in the flood of May-June 1935 on the Republican River, they were extremely high in the period covered by this report. Loss of life, which resulted largely from the rapid cresting of the streams, was likewise high. Each of the floods was caused by heavy precipitation, which at times reached intensities seldom recorded in the Missouri River basin. On May 8, 1950, more than 14 inches of rain fell over certain areas of the Little Nemaha River basin within a period of a few hours. One center of the storm of July 8, 1950,occurred at York, Nebr., where 11 inches of rain was recorded within a 4-hour period, and the storm total exceeded 13 inches. Notable high rates of discharge produced by the intense rainfall were 1,030 cfs per square mile from 218 square miles of drainage area in the Little Nemaha River basin on May 9, 1950; 1,020 cfs per square mile from 2.5 square miles drainage area in the Elkhorn River basin on June 2, 1950; and 3,320 cfs per square mile from 6.93 square miles of drainage area in the Big Blue River basin on July 9, 1950. This report presents records of stage and discharge for the flood. periods at 36 stream-gaging stations in southeast Nebraska, and a summary of peak discharges, with comparative data for previously known floods at 45 measurement points. The report also includes a discussion of the weather associated with the floods and other data pertinent to the floods.

Understanding and finding solutions to the problem of sedimentation in the National Wildlife Refuge System

The National Wildlife Refuge System (Refuge System) is a collection of public lands maintained by the U.S. Fish and Wildlife Service for migratory birds and other wildlife. Wetlands on individual National Wildlife Refuges (Refuges) may be at risk of increased sedimentation because of land use and water management practices. Increased sedimentation can reduce wetland habitat quality by altering hydrologic function, degrading water quality, and inhibiting growth of vegetation and invertebrates. On Refuges negatively affected by increased sedimentation, managers have to address complex questions about how to best remediate and mitigate the negative effects. The best way to account for these complexities is often not clear. On other Refuges, managers may not know whether sedimentation is a problem. Decision makers in the Refuge System may need to allocate resources to studying which Refuges could be at risk. Such analyses would help them understand where to direct support for managing increased sedimentation. In this paper, we summarize a case study demonstrating the use of decision-analytic tools in the development of a sedimentation management plan for Agassiz National Wildlife Refuge, Minnesota. Using what we learned from that process, we surveyed other Refuges in U.S. Fish and Wildlife Service Region 3 (an area encompassing the states of Illinois, Indiana, Iowa, Ohio, Michigan, Minnesota, Missouri, and Wisconsin) and Region 6 (an area encompassing the states of Colorado, Kansas, Montana, Nebraska, North Dakota, South Dakota, Utah, and Wyoming) about whether they experience sediment-related impacts to management. Our results show that cases of management being negatively affected by increased sedimentation are not isolated. We suggest that the Refuge System conduct a comprehensive and systematic assessment of increased sedimentation among Refuges to understand the importance of sedimentation in context with other management problems that Refuges face. The results of such an assessment could guide how the Refuge System allocates resources to studying and managing widespread stressors.
