Hydrology and trout populations of cold-water rivers of Michigan and Wisconsin Hydrology and trout populations of cold-water rivers of Michigan and Wisconsin
Statistical multiple-regression analyses showed significant relationships between trout populations and hydrologic parameters. Parameters showing the higher levels of significance were temperature, hardness of water, percentage of gravel bottom, percentage of bottom vegetation, variability of streamflow, and discharge per unit drainage area. Trout populations increase with lower levels...

Water resources of the Lower Minnesota River Watershed, south-central Minnesota Water resources of the Lower Minnesota River Watershed, south-central Minnesota
The lower Minnesota River watershed, an area of 2,005 square miles, is fairly flat west of the Minnesota River, but rises to a hilly ridge along the east side of the watershed. Most of the area is covered by ground moraine cut deeply by the Minnesota River and less deeply by its tributaries. Surface drainage is toward the Minnesota River at the northeast corner of the watershed. The...

Water resources of the Snake River watershed, east-central Minnesota Water resources of the Snake River watershed, east-central Minnesota
Glacial drift overlies sedimentary, igneous, and metamorphic rocks in the Snake River watershed. The Snake River, which drains an area of about 1,030 square miles, originates in an extensive area of peat bogs in the northern part of the watershed. It flows southward across gently rolling glacial terrain in which the major relief is near the river. Near the southern boundary of the...

Effects of TFM and Bayer 73 on in vivo oxygen consumption of the aquatic midge Chironomus tentans Effects of TFM and Bayer 73 on in vivo oxygen consumption of the aquatic midge Chironomus tentans
Exposure of fourth instar larvae of Chironomus tentans to 2.0-8.0 mg/liter of TFM (3-trifluormethyl-4-nitrophenol) for 6 hr at 22 A? 0.5 C in soft water resulted in a significantly increased rate of larval oxygen consumption compared to that of control larvae, as measured with the Warburg respirometer. Maximum stimulation of oxygen consumption occurred with 8.0 mg/liter of TFM, and 1.0...

Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish Gas-liquid chromatographic determination of 3-trifluoromethyl-4-nitrophenol residues in fish
A procedure for the determination of 3-trifluormethyl-4-nitrophenol (TFM) in fish tissues is described. Homogenized tissues are extracted with hexane-ethyl ether; the extract is cleaned up by partitioning the TFM from the extracting solvent into 0.1N NaOH, acidifying the aqueous solution, and partitioning again with hexaneethyl ether. The TFM is methylated with diazomethane and analyzed...

Water resources data for Michigan, water year 1974; Part 2, Water quality records Water resources data for Michigan, water year 1974; Part 2, Water quality records
Water resources data for the 1974 water year for Michigan include records of data for the chemical and physical characteristics of surface and ground waters. Data on the quality of surface water (chemical, temperature, and sediment) were collected from designated sampling sites at predetermined intervals such as once-daily, weekly, monthly or less frequently, and at some sites data were...
