An Analysis of Salinity in Streams of the Green River Basin
Abstract: Dissolved-solids concentrations and loads can be estimated from streamflow records using a regression model derived from chemical analyses of monthly samples. The model takes seasonal effects into account by the inclusion of simple-harmonic time functions. Monthly mean dissolved-solids loads simulated for a 6-year period at U.S. Geological Survey water-quality stations in the Green River Basin of Wyoming agree closely with corresponding loads estimated from daily specific-conductance records. In a demonstration of uses of the model, an average gain of 114,000 tons of dissolved solids per year was estimated for 6-year period in a 70-mile reach of the Green River from Fontemelle Reservoir to the town of Green River, including the lower 30-mile reach of the Big Sandy River.

Analysis of Stream Quality in the Yampa River Basin, Colorado and Wyoming
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 and procedures used to determine ambient stream quality in the Yampa River basin have been presented in detail so that their applicability to other river basins can be determined. For the planner and decision maker, the results presented in this report are summarized in less technical terms in phase-l (Steele and others, 1979) and phase-ll summary reports.

Analysis of Waste-Load Assimilative Capacity of the Yampa River, Steamboat Springs to Hayden, Routt County, Colorado
From purpose and scope: The primary purpose of the study was to aid in evaluating the waste-load assimilative capacity of the study reach for a minimum mean 7-day low flow and 10-year recurrence interval. The results of this analysis will provide planners and managers in Routt County with information for determining the waste-load capacities of the study reach for possible design and operational alternatives of future wastewater-treatment plants.

Application of Remote-Sensing Techniques to Hydrologic Studies in Selected Coal-Mined Areas of Southeastern Kansas
Report describing a study to use remote-sensing techniques to look for relationships between disturbances of the land, water, and vegetation with underground coal mines in the Cherry Creek basin of Kansas. The study looked at color and color-infared photographs, compared with water-quality data to successfully identify contamination and other potential problems.

Application of Thermal Imagery and Aerial Photography to Hydrologic Studies of Karst Terrane in Missouri
From abstract: Planning waste-disposal facilities and impoundments is complicated by karst carbonate terrane in the Ozarks. Thermal imagery (8-13 micrometer wavelength) and color infrared photography aid in identifying losing streams, sinkholes and hydrologic conditions encouraging collapse. Imagery and photography were acquired in Greene and Reynold Counties, Mo., in March 1972 and June 1973. Differences in thermal levels correlating with losing and gaining reaches of Logan Creek valley, Reynolds County, were not visually apparent in predawn March imagery but statistical analysis of predawn magnetic-tape data indicated greater variance in emitted energy from the losing reach than from the gaining reach.

Appraisal of the Interconnection Between the St. Johns River and the Surficial Aquifer, East-Central Duval County, Florida
From introduction: The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, conducted a 1-year study to determine the effects of proposed deepening of the navigation channel on the surficial aquifer. A specific objective was to determine the degree of interconnection that exists current between the limestone adjacent to the river and the limestone in the riverbed that is to be dredged.

Areal Extent of a Plume of Mineralized Water from a Flowing Artesian Well in Dade County, Florida
Abstract: A flowing artesian well tapping the Floridan aquifer at Chekika Hammock State Park, Dade County, Florida, has been contaminating the overlying Biscayne aquifer with saline water since 1944. The contaminating plume extends approximately 7 miles downstream and southeast of the well and ranges in width from 1 to 2 miles. The area of contamination is approximately 12 square miles. The primary contaminating chemical constituents are chloride, sodium, and sulfate ions.

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.
