Reservoir Development Impacts on Surface-Water Quantity and Quality in the Yampa River Basin, Colorado and Wyoming
From introduction: This report describes the results of an investigation in which three computer models were used to evaluate different levels of the proposed reservoir development. One model simulated streamflow conditions with alternative multireservoir configurations; a second model simulated the dissolved-solids concentrations at various locations in the basin; and a third model used streamflows and dissolved solids concentrations to simulate the water-quality conditions within certain proposed reservoirs. This study was designed to demonstrate the application of computer-modeling techniques in evaluating impacts of proposed reservoirs.

Determination of Dissolved Aluminum in Water Samples
From introduction: The purpose of this report is to test the accuracy and precision of the MIBK extract technique and its suitability for A1 determination in rain, surface waters, ground waters, and effluents obtained from leaching various types of rocks with acidified water. The present study investigates the accuracy, precision, and detection limit of this technique and reports methods for improvement. The purpose of the report also is to test the effect of filtration of water samples and the storage of samples in conventional polythylene (CPE), linear polythylene (LPE), and polypropyene (PP) bottles on accuracy of A1 determination.

Evaluation of the Effects of Lake Audubon on Ground- and Surface-Water Levels in the Lake Nettie Area, Eastern Mclean County, North Dakota
Purpose and scope: The purpose of this investigation is to describe changes in the ground-water levels and levels of surface-water bodies and to ascertain whether those changes can be ascribed to the raising of the level of Lake Audubon, or to the subsequent filling of the McClusky Canal, or both. The changes will be determined by analysis of water-level records obtained from observation wells.

Geohydrology of the Meadowbrook Artificial-Recharge Site at East Meadow, Nassau County, New York
Purpose and scope: The Meadowbrook artificial-recharge project, a cooperative effort between the U.S. Geological Survey and the Nassau County Department of Public Works (NCDPW) since 1975, is intended to demonstrate the feasibility of using reclaimed wastewater to replenish and improve the quality of Long Island's ground water. This report presents the results of geologic, hydrologic, and hydrochemical studies that were done at the Meadowbrook artificial-recharge site to define conditions prevailing before the start of recharge operations.

Preliminary Plasma Spectrometric Analyses for Selected Elements in some Geothermal Waters from Cerro Prieto, Mexico
Abstract: As part of a cooperative study with the Geologic Division of the U.S. Geological Survey, water samples collected from geothermal power production wells at Cerro Prieto, Mexico, were analyzed for selected elements by d.c. argon plasma emission spectroscopy. Spectral interferences due to the presence of high concentrations of Ca, Si, Na, and K in these waters affected the apparent concentration values obtained. These effects were evaluated and correction techniques were developed and applied to the analytical values. Precipitates present in the samples at the time of analysis adversely affected the accuracy, precision and interpretability of the data.

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

Flood in Kansas City, Missouri and Vicinity, August 12-13, 1982
Purpose and scope: This report has been prepared to document these significant floods for future hydraulic and hydrological planning; to provide streamflow information required for orderly development of river basins where the hazard of extreme flooding exists; and to further the general hydrologic knowledge available for Missouri rivers and streams. Streamflow data in the report include peak stages and discharges, flood hydrographs, flood-crest profiles, flood volumes, and flood-frequency information. Descriptions of the storm and of the damages resulting from these floods are given.
