A Limnological Study Of Ricks Pond And The Gulpha Creek Drainage In Garland County, Arkansas, Tom M. Buchanan, James Houston, Joe F. Nix, Richard L. Meyer, Eugene H. Schmitz
Arkansas Water Resources Center Technical Reports
A limnological investigation of Ricks Pond and the Gulpha Creek drainage of Garland County, Arkansas was conducted between 1 June 1978, and 21 August 1978. Water samples taken from ten stations on three different dates indicated that the stream and pond systems were typical in water quality characteristics of other small, high gradient streams and impoundments in the Ouachita Mountains of Arkansas. In Ricks Pond, thermal stratification occurred along with the development of an oxygen deficient zone below a depth of one meter. Other water quality parameters indicated that Ricks Pond is a moderately productive ecosystem, with the productivity limited …
A Primary Ecological Survey Of Dardanelle Reservoir Prior To Nuclear Facility Effluent Discharge, Clarence B. Sinclair, Robert L. Watson
A Primary Ecological Survey Of Dardanelle Reservoir Prior To Nuclear Facility Effluent Discharge, Clarence B. Sinclair, Robert L. Watson
Arkansas Water Resources Center Technical Reports
A preliminary ecological survey of Dardanelle Reservoir during the construction phase of Arkansas Power and Light Company's nuclear generating facility was conducted from January 1970 through June 1974. The reservoir is characterized by relatively shallow depths and a high flow-thru rate. A number of features were associated with these characteristics. The reservoir carried a great deal of suspended material and exhibited high turbidities throughout most of the year. Typical thermal stratification and oxygen depletion were only rarely observed. Many of the physico-chemical parameters exhibited relatively high values in comparison to other Arkansas lakes and reservoirs, but due to absence of …
Zooplankton Limnology Of Beaver And Degray Reservoirs In Arkansas, Eugene H. Schmitz
Zooplankton Limnology Of Beaver And Degray Reservoirs In Arkansas, Eugene H. Schmitz
Arkansas Water Resources Center Technical Reports
Research during the year 1975-76 continued to emphasize studies of seasonal changes in patterns of zooplankton abundance and biomass in Beaver and DeGray Reservoirs. Zooplankton samples were taken monthly from three stations on Beaver Reservoir (Figure 1) during the period May 1975 through May 1976. Collections from DeGray Reservoir were made weekly from a single station (Station 1) during the period April 1975 through December 1975. Beaver collections were obtained by taking oblique tows using a Miller sampler equipped with no. 10 mesh. The DeGray program entailed stratified vertical samples taken at 5 intervals to 20 a and 20 m …

Sampling point locations and analytical procedures remained unchanged from those outlined in previous Buffalo National River Ecosystem reports. The only significant change in analytical procedures was a reversion to the glass fiber filter method for collection and extraction of samples for chlorophyll analysis. This change was neeessitated by a need for filtering a larger volume to obtain enough chlorophyll for an accurate measurement. Samples were collected monthly from April 9 through December 30. No samples were taken in January or February due to the extremely uncertain traveling conditions caused by the frequent snows. Prior research indicates that the December 30 …

The Buffalo River originates in the Ozark plateau in Newton County, Arkansas. This magnificent Ozarkian wilderness river is about 238 km long and flows north-eastward to its confluence with the White River. The Buffalo River drains 3,465 km2 and has some 30 named tributaries. In its upper reaches, huge multicolored cliffs extend nearly 213 m above the river as it flows through mountainous countryside which reaches an elevation of 732 m. Within its watershed may be found 700 species of plant life, a habitat for 250 species of birds, and a variety of game animals. In its aquatic habitat …

Samples for water quality analyses and phycological studies were taken from the nine standard sampling locations on the Buffalo River nine times during the period from March 1976 through February 1977. The April-June 1976 samples represent nearly identical conditions throughout the spring period; therefore, emphasis was placed on taxonomic research. As the early January sample was considered sufficient~y reflective of stable winter conditions, the December and February periods were. used for detailed microscopic examination of the rich and diverse diatom flora that was found in the river this year. A total of 273 taxa of diatoms were identified from the …

The priorities were established for the Buffalo National River Ecosystem Studies through meetings and correspondence with Mr. Roland Wauer and other personnel of the Office of Natural Sciences, Southwest Region of the National Park Service. These priorities were set forth in the appendix of contract no. CX 700050443 dated May 21, 1975.
Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase Ii, Richard L. Meyer
Biochrome Analysis As A Method For Assessing Phytoplankton Dynamics Phase Ii, Richard L. Meyer
Arkansas Water Resources Center Technical Reports
Selected chemical, physical and biological parameters were determined for a man-made lake, Beaver Lake, on the White River of Arkansas and Missouri. The research program determined the qualitative and quantitative aspects of the temporal and spatial distribution of the algal subcommunities. It was determined that the epipelic, epilithic, epizooic and metaphytic subcommunities had little influence on the euplanktonic subcommunity. The relationship between the qualitative and quantitative analysis of the biochromes chlorophyll-a, -b, and -c and the phytoplankton species clustered into biochrome sets is discussed. The temporal and spatial distributional patterns of temperature, oxygen, ammonia-N, nitrate-N, orthophosphate-P and silicates are described …

A Survey Of The Fishes Of The Mulberry River, Arkansas, Larry L. Olmsted, Gary D. Hickman, Donald G. Cloutman
A Survey Of The Fishes Of The Mulberry River, Arkansas, Larry L. Olmsted, Gary D. Hickman, Donald G. Cloutman
Arkansas Water Resources Center Technical Reports
Announcement of plans to dam Mulberry River, Arkansas, by the United States Army Corps of Engineers has generated some dispute. Most agruments against damming the stream revolve around environmental degradation and loss of aesthetic values. This report serves as a pre-impoundment survey of the fishes of the Mulberry River so that possible effects of impoundment can be more objectively assessed. Knowledge on the fishes of the Mulberry River is severely lacking. The first study was by Jordan and Gilbert (1886) who collected in the southern U.S. in July, August, and September, 1884. They collected in many streams in Arkansas including …

A Study Of Phytoplankton Dynamics In Lake Fayetteville As A Means Of Assessing Water Quality, Richard L. Meyer
Arkansas Water Resources Center Technical Reports
Phytoplankton community was analyzed for seasonal and vertical distribution in Lake Fayetteville. This northwest Arkansas reservoir maintains a stable water level and chemical input with a relatively constant, slow overflow. Its source is groundwater seepage through a calcareous substrate with little contribution from the limited drainage basin. Phytoplankton community development with its associations and assemblages, chlorophylls -a, -b and c, and biomass distribution are described. The seasonal cycles of the chemical parameters NH4-N, NO2-N, NO3-N, ortho-phosphate, silicon, pH, HCO3- and total-alkalinity plus oxygen are described and discussed. The physical parameters of temperature, light and climate are included. The interaction of …
