Water temperatures of Kentucky

The U.S. Geological Survey in cooperation with the Kentucky Geological Survey has been gathering temperature data on streams throughout Kentucky under a number of different programs for several decades. Periodic water temperature observations, which were made at a frequency of approximately once per month during the past 15 years, were analyzed with the aid of a computer program to describe the annual water temperature cycle at sites in the Commonwealth. Shown on a map of Kentucky, at each site of water-temperature collections, are maximum median monthly temperature, minimum median monthly temperature, and annual average temperature. Stream temperatures in Kentucky vary between 0 and 30 degrees Celsius (deg C) during the year. Maximum median monthly water temperatures occur in July and are typically between 23 and 27 deg C, whereas minimum median monthly water temperatures are recorded in January and are useually within the 2 to 6 deg C range. Annual average water temperatures are between 10 and 18 deg C. (Woodard-USGS)

Ground water in the alluvium along the Kentucky River between Carrollton and Frankfort, Kentucky

A study was undertaken to define the potential of the Kentucky River alluvial aquifer between Frankfort and Carrollton, Kentucky. An inventory of existing water wells showed that one well yielded water at a rate exceeding 300 gal/min. However, six out of the ten holes that were augered into the alluvium contained little or no water-bearing sand or gravel. Water-level data were collected from test wells installed in four of the augered holes. These data, collected when the aquifer was stressed by a flood wave in the Kentucky River, were analyzed by computer in an attempt to determine aquifer diffusivity. The method was unsuccessful due to the exceedingly heterogeneous nature of the aquifer. The probability of constructing a water well in the alluvium capable of yielding more than a few gallons per minute seems to be low. Test drilling is an essential step for those users seeking a moderate-to-large water supply from the Kentucky River alluvial aquifer.

Ground water in the alluvium along the Levisa Fork of the Big Sandy River between Louisa and Pikeville, Kentucky

A study was undertaken to define the potential of the Levisa Fork alluvial aquifer between Louisa and Pikeville, Kentucky. An inventory of existing water wells disclosed no public or industrial use of water from the alluvium, and very few screened wells drilled in the alluvium for domestic supply use. Ten test holes were augered into the alluvium to the bedrock valley floor. Although all of these holes disclosed a substantial thickness of alluvium, seven holes contained virtually no aquifer material. However, in the other three holes as much as 50 feet of clean, coarse sand and gravel was encountered, much of which would be saturated and probably in good hydraulic connection with the Levisa Fork when it is at higher stages. The probability of constructing a water well in the alluvium that is capable of yielding more than a few gallons per minute seems to be low. Test drilling is an essential step for those users seeking a moderate to large water supply from the Levisa Fork alluvium.

Simulated drawdown for selected well fields in the Ohio River alluvial aquifer

Drawdown due to pumping was simulated for three sites in the alluvial aquifer adjacent to the Ohio River by digital modeling techniques. Two well-field arrangements were used at each site. The initial well-field arrangement at each site consisted of three wells located in a line parallel to the Ohio River. The simulated wells were 350 feet (107m) apart and 500 feet (152m) from the river. Pumping was simulated at a rate of 1,500 gal min -1 (5,678 1 min -1 ) for 256 days. The second well-field arrangement allowed comparison of drawdown between the initial well-field arrangement and (a) wells located 350 feet (107m) nearer the river, (b) additional wells, located between the initial well field and the bedrock valley wall and (c) wells located on a line perpendicular to the river rather than parallel to the river. A verification procedure for the digital model based on observed aquifer response to a flood on the Ohio River is included as an appendix.

An outbreak of a hemorrhagic disease in white-tailed deer in Kentucky

In 1971, an outbreak of a hemorrhagic disease occurred in captive and free-ranging white-tailed deer ( Odocoileus virginianus ) in Mammoth Cave National Park, Kentucky. Clinical signs and gross pathological lesions were consistent with those of epizootic hemorrhagic disease and bluetongue, as were serological and histopathological findings for samples sent to other laboratories. The infection rate among the 104 captive deer was 88-92%, and that among the free-ranging Park deer appeared to be similar. Mortality was negligible in the Park deer, but 65 (62%) of the captive deer died. The deaths were bimodally distributed over a 36-day period, and the mortality rate decreased from 97-100% for deer clinically ill during the first 17 days of the outbreak to 58% for deer first exhibiting clinical signs on day 16 or later. Mortality was equal in males and females, but less in yearlings than among fawns or adults. Winter mortality among survivors of the initial outbreak was associated with low ambient temperatures and sometimes fungal and bacterial abscesses, possibly sequelae or complications of the hemorrhagic disease. The pregnancy and birth rates among surviving does appeared to be normal.

Low-flow characteristics of Kentucky streams - A preliminary report

The U.S. Geological Survey has been gathering low-flow data on streams throughout Kentucky for several decades. Much of the data now have been analyzed to determine the frequency of the annual low flow on those streams. Knowledge of the magnitude and frequency of low flow is necessary for planning, managing, and protecting water resources of the Commonwealth. Some specific uses are to analyze potential water-supply capacity, for control of water quality, and for the management of recreation potential. This preliminary report presents a low-flow characteristic at each site where defined, and where the flow is not significantly regulated. That characteristic, the 7-day, 10-year low flow, is the one which seems to be most in demand because of its use in water quality planning and control.

The landslide at Cumberland, Harlan County, Kentucky

A landslide developed on Sanctified Hill, on the east side of Cumberland, Kentucky on December 10, 1972. Since then the slide has rendered 17 dwellings and a church unusable. The slide is in a shallow amphitheater, on plastic sandy clay up to 30 feet thick, lying on top of sandstone and shale (Norton Formation). The bedrock dips 22° south, the same direction as the slope of the hill. The slide is a rotational slump 600 feet long and 500 feet wide at the toe. Movement is in the order of 10 feet downslope. The ground in the area of the slide is wet with natural seepage along the bedrock surface of about 1/2 cubic foot per minute for every 40 feet of bedrock exposure. Leakage from water mains, added to the ground water, is the probable triggering mechanism of the slide. The slide does not pose an immediate further danger unless an abnormally heavy rainfall were to occur. The slide has developed to the point where stabilization is not economically practicable. Relocation of homes appears to be the most suitable solution to the problem.

Derivation of homogeneous streamflow records in the upper Kentucky River basin, southeastern Kentucky

Decisions regarding municipal water supply and additional reservoir construction in the Kentucky River basin dictate the need for increased knowledge of Kentucky Diver low-flow characteristics. Digital computer programs were developed ta route streamflow through reservoir and stream reach components of a stream system. Using these programs as submodels, with availatle observed data, and utilizing appropriate data-handlinq techniques, a digital model of the Upper Kentucky River basin was developed. This model was specifically used to simulate streamflow data which would be adequate to determine the characteristics at tock 10 on the Kentucky River near Winchester, low-flow Kentucky for thirty-one years of regulated conditions. Model inputs consisted of (1) operation criteria for an existing reservoir; reservoir and (2) observed streamflow data for twenty-one years of natural and ten years of:regulated These conditions. techniques are also suitable for studying alternative modeling streamflow requlation schemes and expanding networks of homogeneous streamflow data for regional analyses.

Water resources data for Kentucky, water year 1972: Part 1. Surface water quality

Surface-water records for the 1972 water year for Kentucky, including records of streamflow or reservoir storage at gaging stations, partial-record stations, and miscellaneous sites, are given in this report. The location of all gaging stations is shown in figures 1 and 2. Records for a few pertinent gaging stations in bordering States also are included. The records were collected and computed by the Water Resources Division of the U.S. Geological Survey under the direction of R. V. Cushman, district chief. These data represent that portion of the National Water Data System collected by the U.S. Geological Survey and cooperating State and Federal agencies in Kentucky. Through September 30, 1960, the records of discharge and stage of streams and canals and contents and stage of lakes or reservoirs were published in an annual series of U.S. Geological Survey water-supply papers entitled "Surface Water Supply of the United States." Since September 30, 1960, the records have been or will be published in a series of Geological Survey water-supply papers on a 5-year basis. Beginning with the 1961 water year, surface-water records have been released by the Geological Survey in annual reports on a State-boundary basis. Distribution of these reports is limited; they are designed primarily for rapid release of data shortly after the end of the water year to meet local needs.
