Laboratory studies on antimycin A as a fish toxicant
Liquid and sand formulations of antimycin A were tested in laboratory waters of various temperature, hardness, pH, and turbidity against 31 species of fresh-water fish of various sizes and life stages. Each formulation of toxicant was lethal under all water conditions to fish eggs, fry, fingerlings, and adult fish. Trouts are the most sensitive and catfishes the least sensitive. Of the 31 species,

Ground-water flow related to streamflow and water quality
A ground-water flow system in southwestern Minnesota illustrates water movement between geologic units and between the land surface and the subsurface. The flow patterns indicate numerous zones of ground-water recharge and discharge controlled by topography, varying thicknesses of geologic units, variation in permeabilities, and the configuration of the basement rock surface. Variations in streamf

Analog simulation of ground-water development of the Saginaw Formation, Lansing metropolitan area, Michigan
This report was prepared as a part of the study of the water resources of Clinton, Eaton and Ingham Counties being made for the Tri-County Planning Commission by the Water Resources Division of the U. S. Geological Survey. The report describes one phase of the investigation, that is, the projections of future time-withdrawal-drawdown relationships obtained from an electric analog model study of th

Turnover and urinary excretion of free and acetylated MS-222 rainbow trout, Salmo gairdneri
Rainbow trout (Salmo gairdneri) anesthetized in 100 mg/liter of M.S. 222 at 12 C excreted the drug in free and acetylated forms via the urine during a 24-hr recovery period in freshwater. Of the M.S. 222 excreted, 77-96% was acetylated. Blood levels of free drug in anesthetized trout approximated 75% of the anesthetic concentration, but the amount of acetylated M.S. 222 was relatively insignifican

Geological Survey research 1968: Chapter C
Refractory flint clay and semiflint clay layers, totaling as much as 7% feet in thickness, occur in the lower part of the Allegheny Formation of Pennsylvanian age in north-central Randolph County, W.Va. The deposit seems to be a lens in a widespread bed of plastic clay and may underlie an area of 1-2 square miles. Refractory tests of three samples indicate a pyrometric cone equivalent of cone 30-3

Water resources of the Lac Qui Parle River Watershed, Southwestern Minnesota
The Lac qui Parle River watershed is underlain by thick water-bearing sections of glacial drift and Cretaceous rocks. Drainage is from the Coteau des Praries, a plateau in the southwest, to the Lac qui Parle reservoir, about 800 feet lower than the plateau. The term "watershed" as used in this report refers to that part of the drainage basin (767 square miles) within Minnesota. The total area of t
