Coho salmon (Oncorhynchus kisutch) exposed to an acute, sublethal concentration of 3-trifluoromethyl-4-nitrophenol (TFM) exhibited an increased output of urine when compared with controls, but the urinary excretion of Na, K, Ca, Mg, and Cl was not affected. About 35 times more conjugated TFM than free TFM was excreted during the 24-h study period.

Parasitism of fish by coelenterates is rare and the first North American infection was reported in sturgeon (Hoffman et al., 1974, J Parasitol 60: 548-550). In the USSR parasitism of sturgeon (Acipenser sp.) eggs by the coelenterate Polypodium hydriforme Ussov 1885 has long been reported and investigated [Raikova, 1959, in Parasites of Freshwater Fish and the Biological Basis for their...

The Cedar River Watershed Unit (as established by the states of Minnesota) consists of 1,204 square miles (3,118 square kilometres) of flat or gently undulating plain. The watershed is drained by the Cedar River and several smaller streams that flow south into Iowa and eventually into the Mississippi River. Its easternmost neck is part of a broad, flat, well-drained plain, covered by a...

The Lake of the Woods watershed is an area of about 2,900 square miles (7,500 km), the northern limit of which is part of the boundary between the United States and Canada. Drainage is to Lake of the Woods, either directly or by the Rainy River. The watershed includes about 470 square miles (1,220 km2) of Lake of the Woods, one-third of the lake’s total area. The watershed, a part of the...

This hydrologic atlas represents a part of a comprehensive study of the water resources of southeastern Michigan. Its purpose is to provide information on (1) physical features of the Huron River and its tributaries, (2) characteristics of streamflow, (3) quality of ground and surface water, and (4) availability of ground water. This atlas is one in a series of atlases on several river...

Runoff is the water in a river or stream that results from precipitation falling on the drainage basin. It is the net discharge into the stream from surface-water and ground-water sources with losses occurring from evapotranspiration and other consumptive uses. Runoff can be expressed by a variety of numerical values, but average depth of water over the drainage basin, in inches per year...

This hydrologic atlas represents a part of a comprehensive study of the water resources of southeastern Michigan. Its purpose is the provide information on (1) the physical features of basins for minor streams draining into St. Clair River, Lake St. Clair, Detroit River, and Lake Erie, (2) the characteristics of streamflow, (3) the quality of surface water and ground water, and (4) the

On April 18 between 5 p.m. and 12 p.m. the city of Williamston experienced an intense rain storm that caused the Red Cedar River and the many small streams in the area to overflow their banks and resulted in the most devastating flood since at least 1904. Local officials estimated a loss of \$775,000 in property damage. Damage from flooding by the Red Cedar River was caused primarily by...

On April 18 between 5 p.m. and 12 p.m. an intense rainstorm fell in the Lansing area resulting in extensive flooding. The Federal Disaster Assistance Administration estimated that 175 homes were damaged to at least half their value, 4,500 received some damage, with additional losses to schools, utilities, hospitals, and transportation systems. Early estimates indicated that damages may...

The Viking Basin consists of six glacial outwash areas in Douglas, Ottertail, and Todd Counties, west-central Minnesota. Total area is 340 square miles (880 square kilometres). Soils are sandy and excessively well-drained. Crops grown on the outwash would benefit from supplemental irrigation. Irrigation supplies can be obtained from wells in the surface outwash aquifer in significant...
