Primary Productivity and Nutrient Relationships in Garza-Little Elm Reservoir

Description: A large, multi-basin, reservoir (Garza-Little Elm Reservoir) in north central Texas was studied to determine the relative effects of various parameters on primary productivity. The basins were impounded several years apart,thus allowing the influence of age on water chemistry and biota to be considered. Another principal influence on water quality was secondary sewage effluent that entered one basin from a nearby source.

WATEQF: A FORTRAN IV Version of WATEQ, a Computer Program for Calculating Chemical Equilibrium of Natural Waters

Description: Abstract: WATEQF is a FORTRAN IV computer program that models the thermodynamic speciation of inorganic ions and complex species in solution for a given water analysis. The original version (WATEQ) was written in 1973 by A. H. Truesdell and B. F. Jones in Programming Language/one (PL/1). With but a few exceptions, the thermochemical data, speciation, activity coefficients, and general calculation procedure of WATEQF is identical to the PL/1 version. This report notes the differences between WAT… more

Water-Quality Characteristics of Six Small, Semiarid Watersheds in the Green River Coal Region of Colorado

Description: From introduction: This report presents the data collected from six watersheds in northwestern Colorado and describes an initial step in the regionalization of water-quality characteristics and identification of transferability of data from individual, studied watersheds to unstudied watersheds in northwestern Colorado.

Sulfur Isotopic Composition and Water Chemistry in Water from the High Plains Aquifer, Oklahoma Panhandle and Southwestern Kansas

Description: From introduction: The purpose of this report is to identify the sources of sulfate in ground water using water chemistry and sulfur-isotope data. The possible leakage of water or molecular hydrogen sulfide upward from Permian age rocks into the Tertiary Ogallala Formation in the Oklahoma Panhandle and southwestern Kansas is discussed. The study area consists of Cimmarron, Texas, and Beaver Counties in Oklahoma; and Morton, Stevens, Seward, and Meade Counties in Kansas (figures 1 and 2).

Analysis of Stream Quality in the Yampa River Basin, Colorado and Wyoming

Description: From introduction: This report relates to the first of the above objectives by describing stream quality in the Yampa River basin through 1976, with particular emphasis on conditions from August 1975 through September 1976. The content of this report is, at times, relatively technical. This is intentional. The report is aimed not at planners and decision makers but rather at those persons assigned the task of having to design, implement, and interpret a river basin assessment. The techniques an… more

An Evaluation of Water-Quality Data Obtained at Four Streamflow Daily-Record Stations in Idaho

Description: From introduction: This study is limited to four U.S. Geological Survey stream-flow stations located in Idaho (figure 1). The 6 to 22 years of stations were assembled and evaluated through use of computer techniques for data plotting and regression analysis developed by Steele (1972). Objectives of this evaluation were were (1) to show which parameters were highly correlative with the levels of specific conductance and(or) discharge and (2) to see if any changes in overall chemical character of… more

Preimpoundment Water Quality in the Tioga River Basin, Pennsylvania and New York

Description: Introduction: The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, and aided by the Susquehanna River Basin Commission, investigated the water quality of the Tioga River basin, Pennsylvania. The study, made from September 1973 to September 1978, was designed to evaluate water quality at various sites prior to impoundment. Results of the investigation will aid the Corps of Engineers in designing the operation of three reservoirs that were in the final stages of const… more

Water Chemistry for KER Loop 1- June 29, 1959 to December 31, 1959

Description: One of the primary reasons for operating the high pressure KER loops is to obtain information concerning water quality control characteristics for recirculating water cooled reactors. The KER-1 loop is predominantly carbon steel and approximates the water quality conditions specified for the New Production Reactor (NPR).
