Hydrologic and water-quality data for two small watersheds on Catoctin Mountain, North-Central Maryland, 1987-93
Hydrologic and water-quality data were collected from a precipitation-collection station and from two small watersheds on Catoctin Mountain, north-central Maryland, as part of investigations of acidic deposition and episodic acidification, and their effects on streamwater quality. Detailed descriptions of the site instrumentation in the watersheds, field data-collection techniques, and laboratory

Water-level altitudes 1996 and water-level changes 1990-96 and 1995-96 in the Chicot and Evangeline aquifers, Fort Bend County and adjacent areas, Texas
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1990 in the Chicot and Evangeline aquifers in Fort Bend County and adjacent areas, Texas.

Major sources of nitrogen input and loss in the upper Snake River basin, Idaho and western Wyoming, 1990
Total nitrogen input and loss from cattle
manure, fertilizer, legume crops, precipitation,
and domestic septic systems in the upper Snake
River Basin, Idaho and western Wyoming, were
estimated by county for water year 1990. The purpose of these estimations was to rank input of
nitrogen by source, determine the amount of total
nitrogen potentially available to both ground and
surface water t

Assessment of water quality, nutrients, algal productivity, and management alternatives for low-flow conditions, South Umpqua River basin, Oregon, 1990-92
This report is an evaluation of the effects of nutrient loading on water quality in the South Umpqua River Basin. The study was done by the U.S. Geological Survey in cooperation with Douglas County, Oregon. Five wastewater-treatment plants were shown to contribute less than 15 percent of the flow, but more than 90 percent of the nitrogen and phosphorus, in the South Umpqua River during low streamf

Hydrologic and geochemical factors affecting the chemistry of small headwater streams in response to acidic deposition on Catoctin Mountain, north-central Maryland
Hydrologic and water-quality data were collected at a precipitation-collection station and from two small watersheds on Catoctin Mountain, north- central Maryland, as part of an investigation of episodic acidification and its effects on streamwater quality. Data were collected from June 1990 through December 1993. Descriptions of the water shed instrumentation, data-collection techniques, and labo

Evaluation of Acoustic Doppler Current Profiler measurements of river discharge
Developments in Acoustic Doppler Current Profiler (ADCP) technologies have made these instruments potentially useful for making measurements of discharge in rivers and large streams. Although there have been several laboratory studies and some field experiments, quantitative information on the performance of ADCP's under field conditions is relatively rare but essential to proper assessment of the

Evaluation of scour at selected bridge sites in Indiana
Twenty bridge sites in Indiana were evaluated to determine: the extent of scour during floods, streambed stability, the maximum historical scour, and estimates of potential scour. Historical scour data were collected by means of geophysical methods and used to evaluate the scour-computation procedures recommended by the U.S. Federal Highway Administration and 13 other published pier-scour equation

Availability and quality of water from drift aquifers in Marshall, Pennington, Polk, and Red Lake counties, northwestern Minnesota
Sand and gravel aquifers present within glacial deposits are important sources of water in Marshall, Pennington, Polk, and Red Lake Counties in northwestern Minnesota. Saturated thicknesses of the unconfined aquifers range from 0 to 30 feet. Estimated horizontal hydraulic conductivities range from 2.5 to 600 feet per day. Transmissivity of the unconfined aquifers ranges from 33 to greater than 3,9

Geohydrologic units and water-level conditions in the Terrace alluvial aquifer and Paluxy Aquifer, May 1993 and February 1994, near Air Force Plant 4, Fort Worth area, Texas
The terrace alluvial aquifer underlying Air Force Plant 4 and the adjacent Naval Air Station (formerly Carswell Air Force Base) in the Fort Worth area, Texas, is contaminated locally with organic and metal compounds. Residents south and west of Air Force Plant 4 and the Naval Air Station are concerned that contaminants might enter the underlying Paluxy aquifer, which provides water to the city of

Quality-assurance plan for water-resources activities of the U.S. Geological Survey in Idaho
To ensure continued confidence in its products, the Water Resources Division of the U.S. Geological Survey implemented a policy that all its scientific work be performed in accordance with a centrally managed quality-assurance program. This report establishes and documents a formal policy for current (1995) quality assurance within the Idaho District of the U.S. Geological Survey. Quality assuranc
