Historic Water-Level Changes and Pumpage from the Principal Aquifers of the Memphis Area, Tennessee: 1886-1975

Description: Abstract: Annual pumpage for both the Memphis Sand ("500-foot" sand) and Fort Pillow Sand ("1400-foot" sand) from the time of initial pumping from these aquifers to 1975 is presented in both tabular and graphic forms . The Memphis Sand supplied 188 million gallons per day in 1975 or 95 percent of the total water used in the area . Pumpage from the Fort Pillow Sand has decreased in recent years and in 1975 was about 4 million gallons per day. Pumping increases from the Memphis Sand have caused an almost continual decline of water levels as shown by graphs , tables, and a series of potentiometric-surface maps. Water-level-change maps show the fluctuations in water levels for two periods of high water use. Water levels in the Fort Pillow Sand are also shown by tables and graphs and a potentiometric-surface map . These graphs illustrate a rise of water levels since 1963, coincidental with pumping reductions. The data presented suggest that a constant pumping rate will cause little water-level decline and that the water levels can be altered for efficient resource management by areally varying the distribution of pumping . The references listed support the information presented in this report .

Potentiometric Map of the Memphis Sand in the Memphis Area, Tennessee, August 1978

Description: From explanation: This map is based on water level measurements made in wells screened in the Eocene Memphis Sand (formerly "500-foot sand"). Monthly low-water levels for the month of August, 1978 from USGS maintained recorder equipped wells and supplemental measurements made on August 22 and 23 of private and industrial wells were used as control. Water levels are commonly at their lowest for the year during late August of early September (Criner and Parks, 1976).

Preliminary Evaluation of Flood Frequency Relations in the Urban Areas of Memphis, Tennessee

Description: From introduction: This report describes an alternative approach to developing flood frequency characteristics, and presents results of the application of that technique to small streams in the urban and sub-urban areas of Memphis, Tennessee. The tool used is a regression model, with variations. The use of a parametric rainfall runoff model is not attempted in the analysis.
