Effects of present and projected ground-water withdrawals on the Twin Cities aquifer system, Minnesota Effects of present and projected ground-water withdrawals on the Twin Cities aquifer system, Minnesota
The Twin Cities aquifer system in Minnesota contains 5 aquifers and 4 confining units composed of 14 stratigraphic units. Bedrock aquifers consist of friable sandstones and highly fractured carbonate rocks; aquifers in the glacial drift consist of outwash and alluvium. From 1880 to 1980, groundwater withdrawals had caused long-term declines of water levels of as much as 90 feet in the...

Geohydrology and water quality of Kalamazoo County, Michigan, 1986-88 Geohydrology and water quality of Kalamazoo County, Michigan, 1986-88
Thick, glacial sand and gravel deposits provide most ground-water supplies in Kalamazoo County. These deposits range in thickness from 50 to about 600 feet in areas that overlie buried bedrock valleys. Most domestic wells completed at depths of less than 75 feet in the sands and gravels yield adequate water supplies. Most industry, public supply, and irrigation wells completed at depths...

Physical factors and their influence on the mussel fauna of a main channel border habitat of the upper Mississippi River Physical factors and their influence on the mussel fauna of a main channel border habitat of the upper Mississippi River
The habitats of mussel species in a portion of the main stem of Navigation Pool 10 of the upper Mississippi River were examined. Population composition, abundance, and sediment and current preferences were measured at 186 sites in the East Channel of the pool. Although total mussel abundance varied significantly as a function of sediment and current (p ≤ 0.05), abundance could be...

Liquid-chromatography thermospray mass-spectrometric study of n-acylamino dilactones and 4-butyrolactones derived from Antimycin-A Liquid-chromatography thermospray mass-spectrometric study of n-acylamino dilactones and 4-butyrolactones derived from Antimycin-A
Reversed-phase high-performance liquid chromatography—thermospray mass spectrometric (HPLC—MS) characteristics of four sets of lactonic complexes (one 4-butyrolactones and three dilactone complexes) derived from antimycin A were investigated. Three types of 8-hydroxy analogues were also included in the study. Pairs of a–b structures isomeric at the 8-acyloxy ester side-chains were best...

Benefit-cost analysis of fishery rehabilitation projects: A Great Lakes case study Benefit-cost analysis of fishery rehabilitation projects: A Great Lakes case study
Tools of benefit-cost analysis are used to evaluate a project to rehabilitate the yellow perch fishery of Green Bay, Wisconsin. Both sport and commercial fishers harvest from this stock, which has been suffering from much reduced productivity since the early 1960s. The project is composed of commercial quotas and other regulations. Measures of benefits and costs were used that explicitly

Effects of fish predation on invertebrates associated with a macrophyte in Lake Onalaska, Wisconsin Effects of fish predation on invertebrates associated with a macrophyte in Lake Onalaska, Wisconsin
We tested the effects of fish predation on the macroinvertebrates associated with Vallisneria americana (Michx) by using enclosure/exclosure experiments in lake Onalaska, Wisconsin. Four treatments were used: open water (cageless) controls, cage-effect controls (partially enclosed cages), exclosures (all fish removed), and enclosures (cages stocked with a known density of bluegills...

Matrix-controlled hydraulic properties of Mississippian and Pennsylvanian sandstones from the Michigan Basin Matrix-controlled hydraulic properties of Mississippian and Pennsylvanian sandstones from the Michigan Basin
Hydraulic-conductivity measurements were made of 49 sandstone core plugs using a flow pump and a conventional triaxial confining apparatus. The sandstones tested are samples from the Marshall Sandstone and Grand River and Saginaw Formations, which are the principal bedrock aquifers in the Michigan basin. Sandstones ranging from poorly cemented to well cemented were selected to...
