Water Quality And Benthic Invertebrate Communities In Lake Greeson Tailwater, Stephen B. Smith
Water Quality And Benthic Invertebrate Communities In Lake Greeson Tailwater, Stephen B. Smith
Journal of the Arkansas Academy of Science
The Little Missouri River below Lake Greeson, Arkansas, was sampled for water quality and benthos during summer 1979. The hydropower turbine water intakes, 20 m below the lake surface, released hypolimnetic water into the tailwater. Downstream water temperatures, total organic matter, and total inorganic matter varied considerably and benthic invertebrate communities immediately below the dam were stressed by waters released for power generation. Detrimental effects from altered temperature and flow regimes had decreased by 16.1 km downstream, where invertebrate communities were typical of less stressed environments.
Aquaculture In Cooling Water Recirculated From A Generating Plant, John G. Woiwode, Ira R. Adelman
Aquaculture In Cooling Water Recirculated From A Generating Plant, John G. Woiwode, Ira R. Adelman
Journal of the Minnesota Academy of Science
Recirculating cooling water from an electric generating plant accumulated dissolved and suspended solids up to ten times that of the make-up water from the Mississippi River. Channel catfish (lctalurus punctatus) and tilapia (Tilapia mossambica) were grown In the cooling water, in clear well water, and in a mixture of the two for seven months as part of an investigation of the use of cooling water for commercial aquaculture. Health of both species was generally excellent in test and control waters; growth was commercially acceptable; bioaccumulation of contaminants was negligible. Organoleptic taste quality was not acceptable, although the cause of the …

Wild Commercial Fishery Of Arkansas, Tommie Crawford, Mike Freeze
Wild Commercial Fishery Of Arkansas, Tommie Crawford, Mike Freeze
Journal of the Arkansas Academy of Science
Arkansas' wild commercial fishery industry was surveyed to evaluate commercial fish products produced within the state. The total wild commercial catch for the period of 1 July 1980 to 30 June 1981 was approximately 8,680,124 kg with a value of $6,245,967. These values represent an increase of approximately 3% from the previous year. The bulk of the commercial harvest was made up of buffalo fishes (Ictiobus spp.), catfishes (Ictalurus spp), gars (Lepisosteus spp.) and carp (Cyprinus carpio). The number of commercial fishermen remained relatively unchanged from 1979-1980, with 3,843 licensed fishermen operating on the state's waterways. The number of licensed …

Warmwater Fish Community Of A Cool Tailwater In Arkansas, Richard A. Frietsche
Warmwater Fish Community Of A Cool Tailwater In Arkansas, Richard A. Frietsche
Journal of the Arkansas Academy of Science
A diverse warmwater fish community has persisted in the Lake Greeson tailwater, despite hydropower releases of cold hypolimnetic water. Forty-eight species of fish were collected by electrofishing in the upper 16.1 km of the tailwater. Hydropower releases have reduced the abundance of some of the warmwater sport fish in the upper tailwater, and their populations are probably maintained in part by recruitment from downstream. Angling effort has been diverted from the warmwater sport fish populations to a put-and-take trout fishery.
Effects Of Water Released From Stratified And Unstratified Reservoirs On The Downstream Water Quality, Stephen B. Smith
Effects Of Water Released From Stratified And Unstratified Reservoirs On The Downstream Water Quality, Stephen B. Smith
Journal of the Arkansas Academy of Science
Water quality samples were collected from the Little River system in Pine Creek Lake, Oklahoma, and Gillham Lake, Arkansas, and their associated tailwaters during the winter (reservoirs unstratified) and summer (reservoirs stratified) of 1980. Downstream water quality was not affected by reservoir water releases while the reservoirs were unstratified. When the reservoirs were stratified water quality in the tailwaters was dependent on the release depth of the water. The practice of flushing out a tailwater following an extended low flow period should be examined on a site by site basis. Anoxic water released from a reservoir may contain high amounts …
