Water-use data by category, county, and water management district in Florida, 1950-90
R. L. Marella
1995, Open-File Report 94-521
The population for Florida in 1990 was estimated at 12.94 million, an increase of nearly 10.17 million (370 percent) from the population of 2.77 million in 1950. Consequently, water use (fresh and saline) in Florida increased nearly 510 percent (15,175 million gallons per day) between 1950 and 1990. The resident...

USGS reference materials
Water Resources Division, U.S. Geological Survey
1995, Fact Sheet 207-95
Every year in the United States, millions of measurements are made on the chemical composition of items that affect us on a daily basis. Determining the accuracy of these measurements is based on the analysis of appropriate reference materials whose composition was previously determined through rigorous testing. Today, reference materials...

1995, Open-File Report 95-474
The computed annual yield and deficiency of the subbasins as defined in the Arkansas River Basin Compact, Arkansas-Oklahoma, are given in tables for the 1994 water year. Actual runoff from the subbasins and depletion caused by major reservoirs in the compact area also are given in tabular form. Monthly maximum,...
Quality assurance plan for discharge measurements using broadband acoustic Doppler current profilers
S. W. Lipscomb
1995, Open-File Report 95-701
The recent introduction of the Acoustic Doppler Current Profiler (ADCP) as an instrument for measuring velocities and discharge in the riverine and estuarine environment promises to revolutionize the way these data are collected by the U.S. Geological Survey. The ADCP and associated software, however, compose a complex system and should...

Regression models of monthly water-level change in and near the Closed Basin Division of the San Luis Valley, south-central Colorado
Kenneth R. Watts
1995, Water-Resources Investigations Report 93-4209
The Bureau of Reclamation is developing a water-resource project, the Closed Basin Division, in the San Luis Valley of south-central Colorado that is designed to salvage unconfined ground water that currently is discharged as evapotranspiration. The water table in and near the 130,000-acre Closed Basin Division area will be lowered...
Geohydrology and water quality of stratified-drift aquifers in the Saco and Ossipee River basins, east-central New Hampshire
