Summary of ground-water hydrological data in Michigan in 1970
G.C. Huffman, T. Thompson
1971, Open-File Report 72-173
The purpose of this report is to make available the records of groundwater levels in principal aquifers of the State through 1970 and to compile other related data, such as records of ground-water pumpage, data on municipal, public and industrial water-supply facilities, and the effects of precipitation on ground-water levels....
Field and office instructions in stream gauging for the Hydrological Survey of Zambia
L. E. Bidwell
1971, Open-File Report 73-24
The importance of water to the basic needs of man is self- evident and needs no particular emphasis. The importance of water to a developing economy cannot be overemphasized. A few decades ago, hydrology was a division of hydraulic engineering and was a tool for project survey, plan, and design....

Geology of the insular shelf south of St. Thomas and St. John, U.S. Virgin Islands
L. E. Garrison, Charles Ward Holmes, James V. Trumbull
1971, Open-File Report 71-117
A reconnaissance study has been made of the geology of the insular shelf south of St. Thomas and St. John, Virgin Islands. High-resolution seismic-reflection profiling reveals that a buried northeast-southwest striking bedrock ridge controls the shallow structure of the eastern portion of the shelf. This ridge is thought to be...

1971, Open-File Report 72-166
Ground-water withdrawals for irrigation increased from about 84,000 acre-feet to 430,000 acre-feet per year between 1960 and 1970 in the northern High Plains of Colorado, causing significant water-level declines in areas where high-capacity wells are concentrated. The number of wells increased from about 500 in 1960 to 2,560 in 1970....

Warren A. Gebert
1971, Open-File Report 71-118
The purpose of this study was to determine the hydrologic characteristics of Hulburt Creek, Sauk County, Wis., in order to evaluate a proposed reservoir. The streamflow characteristics estimated are the low flow, monthly flow, and inflow flood. The study was done by the U.S. Geological Survey in cooperation with the...
Preliminary flood-frequency relations and summary of maximum discharges in New Mexico; a progress report
Arthur G. Scott
1971, Open-File Report 71-251
The magnitude and frequency of floods is defined regionally for streams in New Mexico. An analysis was made, using multiple- regression techniques, relating flood peaks of 2, 5, 10, 25, and 50-year recurrence intervals to selected physical and climatic basin characteristics. The state was divided into three flood regions, and...

Generalized flood-frequency estimates for urban areas in Missouri
Ector Eugene Gann
1971, Open-File Report 71-116
A method is presented for estimating flood-frequency information for urban areas in Missouri. Flood-frequency relations are presented which provide an estimate of the flood-peak discharge for floods with recurrence intervals from 2.33 to 100 years for basins with various degrees of existing or projected urban development. Drainage area sizes for...
