Distribution, Age, And Growth, And Feeding Ecology Of Paddlefish (Polyodon Spathula) In Unaltered Missouri River, South Dakota, Rudolph S. Rosen

Electronic Theses and Dissertations

Four hundred eighty-four paddlefish (Polyodon spathula) were captured 26 June 1975 to 11 August 1976 from an unaltered stretch of Missouri River in South Dakota. Vital statistics were measured on all fish, 171 were sacrificed during the analysis of food habits, and 301 fish were tagged and released. Paddlefish were located by observation, gill netting, and snagging. Paddlefish were primarily found downstream from submerged sandbars from late spring to early fall. The crests of the sandbars were 0.1 to 1.0 m deep and immediately downstream, the depth was 1.5 to 4.5 m, and the current velocity was 0 to 0.3 …

Use Of Stockpods For Nesting By Giant Canada Geese, Paul M. Bultsma

Electronic Theses and Dissertations

A study of giant Canada geese (Branta canadensis maxima) nesting on stockponds in western South Dakota was conducted during 1974 and 1975. Analysis of 10 selected variables at nests on natural sites indicated that distance of water below high water level and percent slope from wetland to horizon, contributed the most to the use of the site. Distance from wetland to horizon and disturbance factors were two important variables measured to determine use of artificial nesting structures. First nests were initiated on 1 April 1974 and 8 April 1975. Twenty-five nests (16 percent) were located on artificial nesting structures, and …

The Aquatic Ecology Of Two Seasonal Marshes In Eastern South Dakota, Walter K. Donaldson

Electronic Theses and Dissertations

Zooplankton, benthos, nekton, aufwuchs, and the physical-chemical limnology of two seasonal marshes in eastern South Dakota were monitored from April-June 1975. Bothwell and Lund Marshes contained water from 15 April-July 1975. The dominant i. ons, Ca ++, Mg+ +, and sulfate, made the water hardness non-carbonate. Floating vegetation, Lemna trisulca and Cladophora sp., became abundant in both marshes during the first week of June, and formed large thick mats by the end of June 1975. Daphnia pulex was the dominant zooplankter in Bothwell Marsh and made up 33% of the zooplankton density during the 1975 season. The population was triacmic, …

Effects Of P.L. 566 Stream Channelization On Wetlands In The Prairie Pothole Region, Ronald E. Erickson

Electronic Theses and Dissertations

The Wild Rice Creek Watershed project, in North and South Dakota was constructed under authority of the Small Watershed Protection and Flood Prevention Act (P.L. 83-566 as amended). Structural measures included 24.7 miles of channelization and four floodwater retarding dams. To measure the degree that channelization influenced drainage of prairie wetlands, drainage rates in a channelized tributary were compared to rates in an unchannelized tributary of Wild Rice Creek. Channelization had a direct impact on wetlands by channel drainage reduction of overbank flows, and by providing drainage outlets. Indirect (secondary) wetland losses are believed to have occurred outside of the …

Analysis Of Aerial Surveys And Tolerance Of Landowners For A Canada Goose Flock In Northeastern South Dakota, Thomas C. Tacha

Electronic Theses and Dissertations

Four hundred rural landowners were interviewed in Day and Marshall counties in South Dakota in 1974 and 1975. These 400 interviews included 200 interviews with landowners living within 6.4 km of the three major summer-fall goose concentration areas and 200 interviews from a random sample of landowners living in the study area. Eighty-six percent of the interviewed landowners indicated that it was a good idea to expand the northeastern South Dakota Canada goose flock from 2,000 to 5,000 birds. Only 6 percent of the landowners had complaints about the geese, despite the fact that 23.5 percent of them had received …

An Evaluation Of The Fishery Resource In A Portion Of The James River, South Dakota Scheduled For Channel Modification, Dennis Tol

Electronic Theses and Dissertations

The fish populations of a 193 km (120 mi) section of the James River between Tacoma Park and Redfield, South Dakota that is scheduled for stream modification under the Oahe Irrigation project were evaluated from October 74 to July 76. Twenty-two species of fish were captured in the James River between Tacoma Park and Redfield, South Dakota. The fishes use the area primarily as a spawning ground and nursery for young-of-the-year. Evidence of spawning was found for 19 species of fish. Only a residual population of forage fishes, young-of-the-year of various species, and a few adult black bullheads attempt to …

Sharp-Tailed Grouse Nesting And Brooding Habitat In Southwestern North Dakota, Stanley C. Kohn

Electronic Theses and Dissertations

The habitat of nesting and brooding sharp-tailed grouse (Pedioecetes phasianellus) was studied 1 April to 25 August 1973 and 1974. The objective of the study was to determine the quality and quantity of vegetation at nest and brood locations of sharp-tailed grouse in relation to available vegetation within pastures. Five range sites, lowland draw, rolling grassland, upland grassland, rocky outcropping, and claypan were studied. Thirty-four females were trapped on dancing grounds and equipped with radio transmitters. Seventeen nests were located by monitoring the movements of transmitter-equipped hens and 26 nests were located through use of cable-chain drag. Height of vegetation …

Shore Erosion At Tangier Island, Robert J. Byrne

Reports

Tangier Island, in Accomack County, Virginia, is the southernmost of a series of islands separating Chesapeake Bay from Tangier and Pocomoke Sounds (Figure 1) . With the exception of three sand ridges, which are the populated areas, the island is low lying marsh and tidal flat deposits with elevations generally below 6 feet (MLW datum).

Fine Scale Circulation Near "Foxtrot" In Hampton Roads, Virginia, Christopher S. Welch, Bruce J. Neilson

Reports

During 1974 the Virginia Institute of Marine Science conducted a series of oceanographic, water quality and modeling studies for the outfall from the proposed Nansemond Wastewater Treatment Plant (VIMS, 1975). One of these studies included dye releases to determine the dispersion and transport of material discharged to Hampton Roads near Pig Point. These dye releases were made from the munitions loading piers known as "Foxtrot".

The proposed outfall, as given in the Facilities Plan is located roughly one kilometer to the east-south-east of Foxtrot. Tidal circulation in Hampton Roads is quite complex and there was concern that the distribution patterns …

Evaluation Of A Recreational Lake Rehabilitation Project, Clyde Brashier

2019: Dr. Clyde Brashier

Lake Herman, a recreational, shallow, warm water prairie lake near Madison, South Dakota drain in extensively cultivated watershed and acts as a siltation basin for a chain of four lakes. The lake is more than half silted in and since 1968 various rehabilitation efforts have been made, including the construction of silt traps and lake dredging.

Continuation of the monitoring of twenty plus chemical levels and biological populations of green algae, blue-green algae and diatoms has revealed two major changes: (1) ortho phosphate and total phosphorus levels (which increased markedly with the beginning of dredging) have decreased since dredging has …

Vegetation Development In Relation To Age Of River Stabilization Structures Along A Channelized Segment Of The Missouri River, John Arthur Vaubel

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

During the summer of 1974, I sampled sites of vegetation representative of successional trends in plant communities along the Missouri River floodplain from Sioux City, Iowa, to Rulo, Nebraska. Five district community types listed from youngest to oldest are as follows: Salix spp. – dominated, Populus deltoides – dominated, Platanus occidentalis-Ulmus rubra – dominated, Tilia americana-Quercus rubra – dominated, and Quercus macrocarpa-Carya ovata – dominated vegetation.

The technique of relating vegetation succession to age of river stabilization structures was found to be useful and offered a quite precise method of developing a timescale …

The Prediction Of Lake Huron Lake-Effect Snowfall Systems, Kenneth F. Dewey

School of Natural Resources: Faculty Publications

Data was collected during the 1971-72 snowfall season for the Lake Huron basin. The bulk aerodynamic approach, as formulated by Priestly, was utilized to estimate the daily average flux of heat and moisture over the lake. It was hypothesized that discriminant analysis could be employed to determine the threshold value (discriminant index) of the energy flux which is necessary for the occurrence of the lake-effect snowfall system. To determine the validity of this threshold value, the discriminant index was applied to a series of historical data. The results of this analysis indicated that the discriminant index could be utilized to …
