A Survey Of Recreational Boating In Newport Harbor, David Dean Burrage
A Survey Of Recreational Boating In Newport Harbor, David Dean Burrage
Marine Affairs Theses and Major Papers
This is a study of the recreational boating industry in Newport Harbor, Rhode Island. It is a facility inventory study as well as a consumer attitude and perception study. In these respects, it amounts to a market survey. Prior to this work, the firms in this city which deal with recreational boaters had no conception of the number of users or geographic area influenced by the services they proffered. There was a need to know if the consumers of these services perceived various problems in Newport Harbor. Among these problems were such things as crowding, pollution, conflicts between user groups, …

Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson
Water Quality Trends In The Las Vegas Wash Wetlands, F. A. Morris, L. J. Paulson
Publications (WR)
The Las Vegas Wash is a wetlands ecosystem that acts to buffer the effects of wastewater discharges on the receiving waters of Lake Mead. The wash is the terminus for the 4,144 km2 Las Vegas Valley drainage basin, emptying into Las Vegas Bay of Lake Mead (Colorado River). It is in the northern Mojave desert, which receives an average of only 10 cm of rainfall annually. The Las Vegas Wash is technically an artificial wetland supported almost entirely by the perennial flows from sewage treatment plants. These flows contribute an average of 3-7 t of nutrients (nitrogen and phosphorus) and …

Limiting Swine Stress With Evaporative Cooling In The Southeast, Robert L. Fehr, K. T. Priddy, Samuel G. Mcneill, Douglas G. Overhults
Biosystems and Agricultural Engineering Faculty Publications
Three-hourly weather data for 7 locations in the Southeast and Central United States were used to evaluate the feasibility of evaporative cooling for reducing swine stress. Stress was defined as a relationship between dry and wet bulb temperatures which exceeded a stress index of 85. This analysis indicates that properly installed evaporative coolers could reduce the number of hours that stress would occur in swine facilities from 89.6 to 96.4% depending on location.

Dispersal And Harvest Of Sage Grouse Utilizing The Test Reactor Area Of The Idaho National Engineering Laboratory, Howard W. Browers, Jr.
Dispersal And Harvest Of Sage Grouse Utilizing The Test Reactor Area Of The Idaho National Engineering Laboratory, Howard W. Browers, Jr.
Electronic Theses and Dissertations
A radio telemetry study of sage grouse (Centrocercus urophasianus) summering at the Test Reactor Area (TRA) on the Idaho National Engineering Laboratory (INEL) in southeastern Idaho was initiated in July 1980. Objectives included determination of habitat use, home range, brood breakup, fall movements, and harvest of sage grouse using the TRA. Supplemental habitat data and fall movement data were collected from sage grouse summering at the Central Facilities Area (CFA) on the INEL in 1982. Seasonal precipitation appeared to influence the period of use of the TRA by sage grouse. Grouse arrived later and left earlier in the wet year …
Rainbow Trout (Salmo Gairdneri) Cage Culture And Primary Production In Eastern South Dakota Dugout Ponds, Michael John Roell
Rainbow Trout (Salmo Gairdneri) Cage Culture And Primary Production In Eastern South Dakota Dugout Ponds, Michael John Roell
Electronic Theses and Dissertations
Rainbow trout (Salmo gairdneri) reared in 1 m³ cages in a South Dakota dugout pond grew and survived as well or better than most cage-cultured rainbow trout reported in the literature. Significant differences (P≤0.01) in mean length, weight, and food conversion, and similarity in relative weight between trout fed 2 and 4% of body weight daily, indicated that the optimum feeding rate was near 3% for this size range (35=100g). Daily rations based on fish size and water temperature need to be developed for trout reared in a lentic environment. The high cost of fingerlings was the limiting factor in …
The Effect Of Waste Stabilization Pond Seepage On Groundwater Quality Of Shallow Aquifers In Eastern North Dakota, David J. Brown
The Effect Of Waste Stabilization Pond Seepage On Groundwater Quality Of Shallow Aquifers In Eastern North Dakota, David J. Brown
Theses and Dissertations
The use of stabilization ponds to dispose of municipal wastes has become popular with many North Dakota cities. When managed properly they are an efficient and economical method of waste disposal and may not adversely affect groundwater quality. In order to achieve efficient treatment, the ponds must be built in sediment that has permeability low enough to inhibit excessive percolation of wastewater into the subsurface. Some North Dakota cities have not met this basic requirement in the construction of their ponds. As a result, insufficiently treated pond liquids are allowed to reach the water table, potentially contaminating groundwater supplies. Three …
The Effect Of Oil-And-Gas Well Drilling Fluids On Shallow Groundwater In Western North Dakota, Edward C. Murphy
The Effect Of Oil-And-Gas Well Drilling Fluids On Shallow Groundwater In Western North Dakota, Edward C. Murphy
Theses and Dissertations
Upon completion of an oil-and-gas well in North Dakota the drilling fluid is buried in the reserve pit at the site. Reclamation of the drill site is expedited by digging a series of trenches which radiate out from the reserve pit, The majority of buried drilling fluid is ultimately contained within these 5-7 metre deep trenches. These fluids are commonly salt-based, i.e. they contain a con centration of 300,000±20,000 ppm NaCl. In addition, these drilling fluids also contain additives including toxic trace-metal compounds.
Four reclaimed oil~and-gas well sites were chosen for study in western North Dakota. The ages of these …
The Effects Of Impoundments On Salinity In The Colorado River, Larry J. Paulson, John R. Baker
The Effects Of Impoundments On Salinity In The Colorado River, Larry J. Paulson, John R. Baker
Publications (WR)
The increase in salinity of our western rivers has been identified as one of the most serious water quality problems in the nation. This is of special concern in the Colorado River where salinity has increased from pristine levels estimated at 380 mg/1 to present-day levels of 825 mg/1 at Imperial Dam. Flow depletions, associated with decreased runoff and increased evaporation and diversions, coupled with high salt loading from natural and man-created sources are considered the primary causes for rising salinity in the river. The urban and agricultural development projected to occur in the basin through this century could deplete …

Effects Of Sewage Pollution In The White River, Arkansas, Arthur V. Brown, Lawrence D. Willis, Peter P. Brussock
Journal of the Arkansas Academy of Science
Recently there has been much emphasis placed on the importance of leaf detritus processing to the energetics of stream invertebrates. This study was designed primarily to assess the effects of municipal effluent on the ability of a stream community to utilize leaf detritus, and secondarily to evaluate the extent of the pollution of the White River by the Fayetteville, Arkansas, effluent discharge. Physical and chemical water quality and benthos were sampled periodically at one station upstream and two stations downstream from the discharge, and in the Richland Creek tributary. Processing of leaf detritus was also studied at each site using …

Inputs of copperfrom anti-fouling paints presently pose an environmental stress on some restricted embayments of the Indian River Lagoon, Florida. Over an 18 mo period, samples of water, suspended matter, sediments, barnacles, clams and crabs from selected sites along the Indian River and the Eau Gallie River, have been analyzed for copper. Higher than normal copper concentrations were consistently observed in the water column, sediments, barnacles and crabs collected from the Eau Gallie Harbor. Point sources of copper could be directly traced to vessel-related activities. From field data and laboratory experiments on the leaching of copper from anti-fouling paints, an …

The Influence Of Lake Powell On The Suspended Sediment-Phosphorus Dynamics Of The Colorado River Inflow To Lake Mead, T. D. Evans, Larry J. Paulson
The Influence Of Lake Powell On The Suspended Sediment-Phosphorus Dynamics Of The Colorado River Inflow To Lake Mead, T. D. Evans, Larry J. Paulson
Publications (WR)
The Colorado River has been successively modified by the construction of several reservoirs, beginning in 1935 with the formation of Lake Mead by Hoover Dam. These reservoirs are located in a chain, and each one has an influence on the nutrient dynamics and productivity of the river and downstream reservoir. Lake Mead derives 98% of its annual inflow from the Colorado River. Historically, the Colorado River inflow was unregulated into Lake Mead. Regulation occurred in 1963, when Lake Powell was impounded by the construction of Glen Canyon Dam, approximately 450 km upstream. The formation of Lake Powell drastically altered the …
Raw Water Quality In The New Charleston, Illinois Pump Storage Reservoir, Kevin G. Lookis
Raw Water Quality In The New Charleston, Illinois Pump Storage Reservoir, Kevin G. Lookis
Masters Theses
Charleston, Illinois, a city located in east-central Illinois, recently implemented a new concept in a raw water system. Due to storage capacity-sedimentation problems in the old Lake Charleston-Embarras River raw water supply, the Charleston Pump Storage Reservoir was constructed. The new system involved building a dike separating the Lake Charleston impoundment from the Embarras River. Water to increase the storage capacity of the reservoir can now be selectively pumped into the impoundment from the river.
Raw water quality in the reservoir was monitored on a weekly basis for a full year from August, 1981 to August, 1982. The levels of …
Residual Phytotoxicity Of Mon-097 In Sludge Enriched Soils, Jennifer A. Woods
Residual Phytotoxicity Of Mon-097 In Sludge Enriched Soils, Jennifer A. Woods
Masters Theses
Aerobically and anaerobically digested sludges were added to soil at concentrations of 0, 1, 5, and 10% (v/v). Dry weights of Avena sativa var. Noble plants, harvested 28 days after planting, were greater with increased sludge concentrations. Plant dry weights were consistently greater with aerobically than with anaerobically digested sludge. MON-097, an acetanilide herbicide, was applied to these soil/sludge mixtures at concentrations of 0, 0.5, 1, 2, 4, 8, 16 and 32 ppm. Residual phytotoxicity of MON-097 was not significantly affected by sludge concentration. These results suggest that increased concentrations of sludge in the soil do not contribute to detoxification …

Fecal Coliform Release Studies And Development Of A Preliminary Nonpoint Source Transport Model For Indicator Bacteria, Everett P. Springer, Gerald F. Gifford, Michael P. Windham, Richard Thelin, Michael Kress
Reports
The effect of grazing on water quality has been documented by bacteriological studies of streams adjacent to grazed areas. Bacterial release from fecal deposits is a parameter of the pollution transport mechanism that is poorly understood. The objective of this study was to determine a fecal coliform release function for cattle fecal deposits. Standard cowpies were rained on with a rainfall simulator, and the fecal coliform counts were determined using the most probably number (MPN) method of enumeration. The fecal deposits were rained on at ages 2 through 100 days. The effects of rainfall intensity and recurrent rainfall were tested. …
