Geology and Mineral Resources of the Northern Part of the North Cascades National Park, Washington (open access)

Geology and Mineral Resources of the Northern Part of the North Cascades National Park, Washington

Introduction: This report was started as part of a study of the North Cascade Primitive Area, an area of about 830,000 acres, which adjoined the Canadian border on the north and which extended from Mount Shuksan on the west to Rock Mountain on the east. In the fall of 1968, Public Law 90-544, 90th Cong., reclassified the North Cascade Primitive Area and certain other national forest lands and created the North Cascades National Park, the Ross Lake National Recreation Area, and the Pasayten Wilderness. Ross Lake National Recreational Area, a corridor 21/2-4 miles wide along the Skagit River and its dammed portions, Ross, Diablo, and Gorge Lakes, separates the park into two parts and separates the northern part of the park from the Pasayten Wilderness. The present study concerns those parts of North Cascades National Park and the Ross Lake National Recreation Area that are north of Skagit River and west of Ross Lake (fig. 1), as well as part of the Mount Baker National Forest west of the park (pl. 2).

Water Resources of the Red River of the North Drainage Basin in Minnesota (open access)

Water Resources of the Red River of the North Drainage Basin in Minnesota

The report consists of three principal sections; environmental setting, water resource management, and the hydrologic system. The environmental setting describes the land and people as related to water resources. The section on water resource management is intended to provide practical information needed for the planning and management of water resources. The section on the hydrologic system is a more technical discussion of water in the Red River basin. The section on water management can be used to locate the water, determine the amount available and its quality; whereas, the section on the hydrologic system describes the operation of the system how water moves through the system and why the quality is as it is.

From purpose of the report: The purpose of this report is to present the available information regarding the relation between the rate of ground-water withdrawal and the rate of decline or artesian pressure in a 40-foot "shell" limestone aquifer that was dewatered during construction of Walter F. George Lock and Dam...The report indicates a potential source of a large supply of ground water available for industrial and other uses in an area readily accessible by barge transportation from the Gulf of Mexico to Columbus, Ga.

Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex (open access)

Salt-Water Movement in the Lower Withlacoochee-Cross-Florida Barge Canal Complex

The intent of the investigation was to determine how salt water from the Gulf moves in the river-canal complex under the influence of various combinations of fresh-water discharge and ocean tide. Information about the extent of inland movement, concentration, frequency of occurrence, and residence times of salt water in the river and canal was sought, particularly during times of farthest upstream movement of the salt water.

Effects of the Urbanization on Floods in the Houston, Texas Metropolitan Area (open access)

Effects of the Urbanization on Floods in the Houston, Texas Metropolitan Area

Abstract: Rainfall and runoff data from drainage basins in the Houston metropolitan area and a 60-year rainfall record for the National Weather Service station, Houston-City, were used to simulate 60 annual flood peaks at 26 sites. Selected frequency characteristics, based on these simulated annual peaks are related to drainage area and percentage of impervious area. These relations which may be used to estimate the flood characteristics at ungaged sites, indicate that in the Houston metropolitan area, complete urbanization increases the magnitude of a 2-year flood nine times and increases the magnitude of a 50-year flood five times.

Magnitude and Frequency of Floods in Small Drainage Basins in Idaho (open access)

Magnitude and Frequency of Floods in Small Drainage Basins in Idaho

Abstract: A method which relates basin characteristics with peak flow characteristics is presented for determining magnitude and frequency of floods on streams with drainage areas between 0.5 and 200 square miles. Regression equations for each of eight regions are presented for determination of the 10-year flood. Peak flows for the 25- and 50-year floods can then be estimated from ratios developed for each region. Regression equations are not developed because of poor definitions for several areas that total about 20,000 square miles. The equations were based on multiple-regression techniques using annual peaks and basin characteristics for 303 gaged sites.

Artificial-Recharge Experiments and Operations on the Southern High Plains of Texas and New Mexico (open access)

Artificial-Recharge Experiments and Operations on the Southern High Plains of Texas and New Mexico

Abstract: Experiments using highly turbid water from playa lakes for injection into the Ogallala Formation have resulted in greatly decreased yield of the recharge wells. Recharge of ground or surface water of good quality has indicated, however, that injection through wells in an effective method of recharging the aquifer. Water that is slightly turbid can be successfully injected for a period of time, but generally results in constantly declining yields and capacity for recharge. Redevelopment through pumping and surging significantly prolongs the life of recharge wells under some conditions. Surface spreading is little practiced on the High Plains, but locally may be a feasible means of artificial recharge.

Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas (open access)

Effects of Ground-Water Development on the Proposed Palmetto Bend Dam and Reservoir in Southeast Texas

Abstract: Ground water continues to discharge into the Navidad and Lavaca Rivers by seepage out-flow even though large amounts of ground water are pumped for irrigation. Although a reduction in streamflow probably has occurred, a complete loss of the low flow of the streams by infiltration to a lowered water table seems remote. The large ground-water withdrawals will continue to cause land-surface subsidence, which will range from 0.012 foot to more than 0.026 foot per year. A minimum of about 0.013 to 0.015 foot of annual subsidence at the upper ends of the proposed reservoir and a maximum of about 0.019 foot near the dam site can be expected. Structural failures of manmade features have not occurred from the subsidence, but regional changes in the land slope have occurred and will continue . Numerous fault traces have been mapped in the area, but most of the faults are inactive. If movement along the fault planes should occur, the vertical displacement probably will not exceed the total subsidence.
