Hydrogeology and water resources of Block Island, Rhode Island
A.I. Veeger, H.E. Johnston, Byron D. Stone, Leslie A. Sirkin
1994, Water-Resources Investigations Report 94-4096
Ground water is present on Block Island as a lens of freshwater that overlies saltwater. Yields of 2 to 5 gallons per minute are obtainable throughout the island, and yields of 25 gallons per minute are possible at many wells. Annual water use during 1990 is estimated to have been...

Hydrogeology of Pleistocene glacial deposits and Jurassic "red beds" in the central lower peninsula of Michigan
David B. Westjohn, Thomas L. Weaver, K.F. Zacharias
1994, Water-Resources Investigations Report 93-4152
Geologic-log data were used to construct thickness and surface-configuration maps of Jurassic deposits, and a map of general composition of Pleistocene glacial deposits, in the central Lower Peninsula of Michigan. These geologic units form the upper part of a regional system of aquifers and confining units in the Michigan Basin....
The adaptive significance of hatching synchrony of waterfowl eggs
Paul L. Flint, Mark S. Lindberg, Margaret C. MacCluskie, James S. Sedinger
1994, Wildfowl (45) 248-254
We estimated the amount of incubation time that first laid Black Brent eggs received before completion of the clutch. First laid eggs received up to 48 hours of incubation before the last egg was laid in Brent clutches. Waterfowl clutches usually hatch within a period of 24 hours, suggesting that...
Lateral movement and stability of channel banks near four highway crossings in southwestern Mississippi
D. Phil Turnipseed
1994, Water-Resources Investigations Report 94-4035
Channel meandering in alluvial streams has caused localized channel instability that has resulted in bridge failure and loss of human life in Mississippi. The U.S. Geological Survey, in coopera- tion with the Mississippi Department of Transpor- tation, conducted a study to develop a better methodology for defining and estimating channel...
Geomorphic response to channel modifications of Skuna River at the State Highway 9 crossing at Bruce, Calhoun County, Mississippi
K.V. Wilson Jr., D.P. Turnipseed
1994, Water-Resources Investigations Report 94-4000
Skuna River at State Highway 9 at Bruce, Calhoun County, Mississippi, has geomorphically responded to channel modifications by lowering of the channel bed through degradation, which heightened and steepened channel banks and induced widening. Skuna River Canal (Skuna River) has typically degraded about 16.5 feet and widened about 150 feet...
Determination of traveltime in the Delaware River, Hancock, New York, to the Delaware Water Gap by use of a conservative dye tracer
K. E. White, T.W. Kratzer
1994, Water-Resources Investigations Report 93-4203
Traveltime of a soluble substance was determined for a 120-mile reach of the Delaware River from the confluence of the East Branch Delaware River and the West Branch Delaware River at Hancock, N.Y. to the Delaware Water Gap. Dye studies were conducted at the 85-95 percent and the 25-30 percent...
Flood discharges and hydraulics near the mouths of Wolf Creek, Craig Branch, Manns Creek, Dunloup Creek, and Mill Creek in the New River Gorge National River, West Virginia
J.B. Wiley
1994, Water-Resources Investigations Report 93-4133
The U.S. Geological Survey, in cooperation with the National Park Service, studied the frequency and magnitude of flooding near the mouths of five tributaries to the New River in the New River Gorge National River. The 100-year peak discharge at each tributary was determined from regional frequency equations. The 100-year...
Reconnaissance of ground-water quality at selected wells in the Beaver Creek watershed, Shelby, Fayette, Tipton, and Haywood Counties, west Tennessee, July and August 1992
A. M. Fielder, A. J. Roman-Mas, M. W. Bennett
1994, Open-File Report 93-366
A reconnaissance of water-quality conditions of the water-table aquifer in the Beaver Creek watershed and other rural areas of Shelby, Fayette, Tipton, and Haywood Counties, Tennessee, was conducted during July and August 1992. The reconnaissance was conducted by the U.S. Geological Survey, in cooperation with the Tennessee Department of Agriculture...
