Ground water for irrigation near Lake Emily, Pope County, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-J
In the Lake Emily area, thickness of the glacial drift ranges from about 200 feet to more than 400 feet. Within the drift are sand and gravel aquifers, some of which can yield adequate water supplies for irrigation. Outwash, as much as 60 feet thick, lies at the surface. The...
Ground-water reconnaissance of selected sites in Rocky Mountain National Park and Shadow Mountain National Recreation area, Colorado
F.A. Welder
1971, Open-File Report 71-320
An evaluation of the ground-water supply potential at 30 sites within the Rocky Mountain National Park and Shadow Mountain National Recreation Area was made by the U.S. Geological Survey in 1967 and 1968. The work consisted of a geohydrologic reconnaissance, well inventory, and test drilling. The study sites are underlain...
Techniques and equipment required for precise stream gaging in tide-affected fresh-water reaches of the Sacramento River, California
Winchell Smith
1971, Water Supply Paper 1869-G
Current-meter measurements of high accuracy will be required for calibration of an acoustic flow-metering system proposed for installation in the Sacramento River at Chipps Island in California. This report presents an analysis of the problem of making continuous accurate current-meter measurements in this channel where the flow regime is changing...
Ground water for irrigation in the Brooten-Belgrade area, west-central Minnesota
Wayne A. Van Voast
1971, Water Supply Paper 1899-E
Water for irrigation is needed to improve crop yields from sandy soils in the Brooten-Belgrade area. Ground-water supplies of sufficient quantity and suitable quality for irrigation are available in much of the area. Quaternary glacial drift, as much as 300 feet thick, is underlain by Precambrian crystalline rocks and possibly by...
