Restoration of freshwater in the Cano Tiburones area, Puerto Rico
Allen L. Zack, Angel Class-Cacho
1984, Water-Resources Investigations Report 83-4071
Cano Tiburones on the north coast of Puerto Rico originally was a shallow, coastal lagoon, 9 square miles in area. It accumulated freshwater from adjacent rivers and springs and drained to the ocean through unobserved subterranean conduits. Forced drainage by pumping of Cano Tiburones for agriculture was begun in 1949,...

Drought-related impacts on municipal and major self-supplied industrial water withdrawals in Tennessee -- Part B
Frank M. Alexander, Lee A. Keck, Lewis G. Conn, Stanley J. Wentz
1984, Water-Resources Investigations Report 84-4074
A state-wide water use survey was conducted of all public water suppliers and large, self-supplied industries in Tennessee. This report contains a summation of the data received from 463 public-water suppliers and 129 self-supplied water users. Analysis of the study results and findings indicate that many communities in Tennessee do...
Habitat Suitability Index Models: Great egret
Brian R. Chapman, Rebecca J. Howard
1984, FWS/OBS 82/10.78
The great egret, also called common egret or American egret, is a large white heron tn the order Ciconiiformes, family Ardeidae. Great egrets stand 94.0-104.1 cm (37-41 inches) tall and have a wing spread to 139.7 cm (55 inches) (Terres 1980). The species is associated with streams, ponds, lakes, mud...
Habitat Suitability Index Models: Eastern cottontail
Arthur W. Allen
1984, FWS/OBS 82/10.66
The eastern cottontail (Sylvilagus floridanus) is the most widely distributed cottontail in North America (Chapman et al. 1982). The species is considered to be a generalist that occupies a variety of habitats from southern Canada southward into South America (Chapman et al. 1980). The eastern cottontail's range overlaps that of...

Preliminary assessment of climatic change during Late Wisconsin time, southern Great Basin and vicinity, Arizona, California, and Nevada
W. G. Spaulding, S.W. Robinson, Frederick L. Paillet
1984, Water-Resources Investigations Report 84-4328
Nine plant macrofossil assemblages from the Eleana Range-2 packrat (Neotoma sp.) midden span 6,500 radiocarbon years and record local vegetational changes in the southern Great Basin of Nevada during the last one-half of the Late Wisconsin glacial age. Climatic reconstructions were developed to account for these changes. During the late...
Simulated ground-water flow in the Potomac aquifers, New Castle County, Delaware
Mary Martin
1984, Water-Resources Investigations Report 84-4007
Flow in three aquifers of the Potomac Formation in New Castle County, Delaware, was simulated. Results of the calibrated flow model show the maximum transmissivity of the lower aquifer is between 1,000 and 1,500 square feet per day; the middle aquifer, between 3,000 and 3,500 square feet per day; and...
Projected water-level declines in the Ogallala aquifer in Lea County, New Mexico
D. P. McAda
1984, Water-Resources Investigations Report 84-4062
A two-dimensional digital ground-water flow model was constructed of the Ogallala aquifer in Lea County, New Mexico. Simulations of predevelopment steady-state and historical pumping conditions were used to fit the model. Projections of water-level declines were made based on the condition of no additional development and the condition of a...
Potential effects of surface coal mining on the hydrology of the Corral Creek area, Hanging Woman Creek coal field, southeastern Montana
N. E. McClymonds
1984, Water-Resources Investigations Report 83-4260
The Corral Creek area of the Hanging Woman Creek coal field, 9 miles east of the Decker coal mines near the Tongue River, contains large reserves of Federal coal that have been identified for potential lease sale. A hydrologic study was conducted in the area to describe existing hydrologic systems...

K.D. Medina, C.O. Geiger
1984, Water-Resources Investigations Report 84-4107
The results of an evaluation of the cost effectiveness of the 1983 stream-gaging program in Kansas are documented. Data uses and funding sources were identified for the 140 complete record streamflow-gaging stations operated in Kansas during 1983 with a budget of $793,780. As a result of the evaluation of the...
Digital simulation of the regional effects of subsurface injection of liquid waste near Pensacola, Florida
M. L. Merritt
1984, Water-Resources Investigations Report 84-4042
Industrial, organic, liquid waste has been injected into a part of the lower limestone of the Floridan aquifer at one site since 1963 and at another site since 1975, raising water levels in the injection zone throughout a large region. The hydrogeologic conceptual model of the injection zone is a...
Cost-effectiveness of the US Geological Survey stream-gaging program in central Florida
R. A. Miller, Warren Anderson, R.C. Heath
1984, Water-Resources Investigations Report 84-4116
In the Red Oak area, Oklahoma, water in shale bedrock occurs in bedding planes and fractures and is confined. Wells probably yield less than 5 gallons per minute. Ground water is a sodium or mixed cation carbonate/bicarbonate type with dissolved-solids concentrations ranging from about 300 to 700 milligrams per liter....
