Investigation of the Suitability of Prepakt Concrete for Mass and Reinforced Concrete Structures

Description: The purpose of the investigation reported herein was to develop data on the suitability of Prepakt concrete for mass concrete dams and for reinforced concrete construction. Prepakt concrete is made by packing the forms with coarse aggregate and then pumping in a cement base intrusion mixture (grout) to fill the voids.

Recommended Practices for Establishment and Maintenance of Turf

Description: "The intent of this report is to provide technical and practical information which will be of value to those responsible for preparation, review or accomplishment of specifications for the establishment of vegetative ground cover. [...] The report is concerned primarily with establishment of turf grasses in the continental United States. A brief discussion of maintenance practices is included as such practices have a direct bearing on the successful establishment of the desired ground cover" (p. 1).

Geohydrology of the Cross-Florida Barge Canal Area with Special Reference to the Ocala Vicinity

Description: From preface: This report is concerned in general with the possible effects of the Cross-Florida Barge Canal on the pre-canal hydrologic regime of the area, and in particular with the effect of the canal on the natural levels, movement, and quality of the ground-water.

Computation of Inflows and Outflows of Eight Regulated Lakes in the Oswego River Basin, New York, 1930-79

Description: Purpose and scope: This report describes (1) methods of computation used to obtain the daily lake inflows and outflows and river discharges; (2) sources of error and their implications for reliability of the computed values; and (3) a technique for smoothing lake-level hydrographs that minimizes the effect of random fluctuations in daily lake-levels resulting from seiche or wind action.

Water-Quality Assessment of Francis E. Walter Reservoir, Luzerne and Carbon Counties, Pennsylvania

Description: Objectives and scope: The principal objectives of this study were to assess the past and current water quality of the impoundment, its major tributaries, and its discharge, and to address the environmental impact of raised pool levels. Data collection was directed toward documenting the temporal and spatial variations in physical, chemical, and biological characteristics of the water, to estimate annual nutrient and suspended sediment loading, and to determine the algal biomass, dominant genera, algal growth potential, and limiting nutrient.

Analysis of Selected Benthic Communities in the Florida Everglades with Reference to Their Physical and Chemical Environment

Description: From purpose and scope: The purpose of this investigation is to document the types of aquatic benthic organisms found within the Everglades and to determine the extent to which the chemical and physical character of surface water and bottom materials affect their distribution and community structure.

Preimpoundment Water Quality of the Wild Rice River, Norman County, Minnesota

Description: From abstract: This report uses water samples collected from two sites at the Wild Rice River in Minnesota to "establish baseline water-quality characteristics before construction of a reservoir near Twin Valley, Minnesota for recreation and flood control." It contains a map, graphs, and tables.

Preimpoundment Water Quality of Raystown Branch Juniata River and Six Tributary Streams, South-Central Pennsylvania

Description: Abstract: The Raystown Branch Juniata River watershed, which is the main water source for Raystown Lake, is a 960-square-mile (2,490 square kilometers) drainage basin in south-central Pennsylvania. Preimpoundment water-quality data were collected on the Raystown Branch and six tributary streams in the basin. Specific conductance values varied inversely with water discharge. The pH values were extremely low only at the Shoup Run site. Dissolved oxygen concentrations observed at all sites indicated a relatively high oxygen saturation level throughout the year. Seasonal variations in nitrate-N and orthophosphate-P levels were measured at the main inflow station at Saxton, Pa. The highest concentrations of nitrate-N and orthophosphate-P occurred in the winter and spring months and the lowest concentrations were measured during the summer and fall. Bacteriological data indicated no excessive amounts of fecal matter present at the in-flows. Soil samples collected at four sites in the impoundment area were predominantly of the Barbour, Philo, and Basher series, which are considered to be highly fertile soils with silt-loam and sandy-loam textures. Morphological features of the lake basin and lo~ nutrient levels at the ·inflows should prevent excessive weed growth around the lake perimeter.

Projected Effects of Proposed Chloride-Control Projects on Shallow Ground Water--Preliminary Results for the Wichita River Basin, Texas

Description: From purpose and scope: The purpose of this report is to present preliminary results of the study by the Geological Survey on the following: (1) The existing ground-water conditions in the shallow fresh-water system in the vicinity of the proposed Truscott Brine Lake (figure 1) and (2) the projection of the post-construction effects of the proposed Truscott Brine Lake on the fresh-water aquifer, especially in relation to changes in hydraulic head but also with respect to possible changes in the chemical quality of the ground water.

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

Description: 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.
