Long Term Vole Control In Ontario Apple Orchards, Zia Siddiqi, W. D. Blaine, Stan Taylor

Eastern Pine and Meadow Vole Symposia

The results obtained so far in this 3 year study have shown that the plots with poisoned bait feeder stations suffered significantly less tree girdling than the plots treated with the fall broadcast application of 2% zinc phosphide. Similar timings were also observed in number of voles per plot, however, the vole population was much lower than the previous year. Considerable interest has been shown by apple growers in adopting this method of vole control at a commercial level.

Efficacy Of Spring Broadcast Rodenticides In The Hudson Valley, New York, Paul F. Steblein, Pamela N. Miller, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

Subsequent to the prohibition of endrin use in New York State, a variety of alternate rodenticides and methods of rodenticide application have been examined in an effort to develop effective control measures for the pine vole, Pitymys pinetorum. These studies indicate that the manner in which the rodenticides are applied substantially influences their effectiveness in controlling pine voles. Specifically, in our experience placing poisoned bait directly in the animal’s subsurface tunnel systems has proved to be the most effective means of vole control. However, this method of bait placement is both time consuming and expensive. An alternate more cost-effective method …

Velsicol Markets More Than A Rodenticide, Velsicol Chemical Corporation

Eastern Pine and Meadow Vole Symposia

Manufacturer's responsibility does not end with production of a high quality bait. There are several excellent rodenticides on the market today, but their effectiveness depends on the applicators understanding of what he is doing and why he is doing it. That's why Velsicol has shifted so much of its emphasis to studying rodent behavior and rodenticide application technology. To provide orchardists with an understanding of the dynamics of orchard vole control, Velsicol developed an educational program based on integration of good management practices with chemical and non-chemical methods of control. The program covers orchard cultural practices, identification of voles, vole …

Nutrients And Acid In The Rain And Dry Fallout At Fayetteville, Arkansas (1980-1982), George H. Wagner, Kenneth F. Steele

Arkansas Water Resources Center Technical Reports

Wet and dry fallout at Fayetteville, Arkansas have been collected separately and analyzed since April, 1980. The precipitation-weighted-average pH for two yearly periods of rainfall were 4.72 (6/80-5/81) and 4.75 (6/81-5/82). This corresponds to a concentration of the acid ion, H+, of about 18 parts per billion (ppb). Pure water in equilibrium with the CO2 of the air would have a pH of 5.65 (2.2 ppb of H+). The range of pH during this two year period was 3.86-7.74(140-0 ppb H+) for the rainfall. Aqueous extracts of the dry fallout were always in the 6.75-7.87 pH range, i.e., neutral to …

A Survey Of Soils Irrigated With Arkansas River Water, John T. Gilmour, H. D. Scott, R. E. Baser

Arkansas Water Resources Center Technical Reports

Interest in the use of Arkansas River water for irrigation has increased recently as land adjacent to the river is converted to crop production and river water is considered as an alternative to depleted underground supplies. Since the Arkansas River can contain elevated concentrations of sodium chloride, this study was designed to determine if soil conditions adverse to crop growth were developing where river water has been used. The impact of river water on sites where river water was used as either the sole source for up to 3 years or as a supplement to another surface source for up …

Interagency Hazard Mitigation: 90-Day Post Flood Recovery Progress Report, Hazard Mitigation Team (Utah)

Elusive Documents

As a result of an extended period of abnormally high precipitation, prolonged snow melt, and subsequent high water tales, Utahns, in 1983 suffered from landslides, debris flows, flooding, and a dam failure. On April 30, 1983, the President determined the Spanish Fork slide-dam and Thistle flood covering Utah, Carbon, and Emery Counties was of sufficient seventy and magnitude to issue a Major Disaster Declaration under Public Law 93-288. The incident period was not closed until July 1, 1983. By the time all flooding had ceased, nineteen additional counties (over 75% of Utah) had been included in the Declaration.

Fisheries Report No 59 - Potential Fisheries Capability Of The Ord In The Short, Medium And Long Terms, Dr N. Morrissy

Fisheries Research Reports

This report examines the history, future and problems of various methods for development and exploitation of the fisheries resources of the Ord.

The primary resource is the array of native fish and crustacean species, with the possible introduction of other desirable or noxious species being a subject for consideration.

Water resources, supporting these species, are the remaining natural Ord River downstream from the Diversion Dam at Kununurra, the stillwaters of Lake Kununurra and Lake Argyle, and, for aquaculture, the controlled distribution of water supply over the flat land of the irrigation system (Fig. 1). Another recognized resource is the climatic …

Planning For Rural Human Services: The Western Energy-Impact Experience, United States Department Of Health And Human Services, Office Of Human Development Services

Fuel Sources

Beginning in the mid-1970's, the development of energy resources in the western United States created significant changes in the small, rural communities of this area. Many of the changes were the result of the rapid influx of population associated with industrial activities. It has long been recognized that communities subject to rapid growth have difficulty meeting the physical facility needs of their residents, such as housing, shopping and school facilities, and sewer and water services. In recent years, a growing recognition of the importance of the social effects of rapid community growth has also developed. These effects include the deterioration …

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

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.

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

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 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 …

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

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 …

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. …

Effects Of Cadmium On Streams And Irrigated Agriculture In The Presence And Absence Of Oil Shale Leachate, Douglas A. Selby, Jean M. Ihnat, Fredrick J. Post, Jay J. Messer

Reports

Artificial streams, soil perfusion columns, and potted plants were exposed to 20 ug Cd/l in the presence and absence of unretorted oil shale leachate. High cadmium accumulations occurred in the stream biota, but did not measurably affect community structure or function. The presence of oil shale leachate had no effect on bioaccumulation or ecosystem structure or function. Nitrification in soil columns was enhanced by the presence of the organic fraction of oil shale leachate, but this effect was not observed when cadmium was present. Crop accumulation of cadmium was somewhat higher in alfalfa and radishes irrigated with leachate, but did …

The Evaluation Of Metals And Other Substances Released Into Coal Mine Accrual Waters On The Wasatch Plateau Coal Field, Utah, Alberta J. Seierstad, V. Dean Adams, Vincent A. Lamarra, Nancy J. Hoefs, Robert E. Hinchee

Reports

Six sites on the Wasatch Plateau were chosen representing subsurface coal mines which were discharging or collecting accrual water on this coal field. Water samples were collected monthly at these sites for a period of 1 year (May 1981 to April 1982). Samples were taken before and after each mine's treatment system. Water sampels were analyzed for major anions and cations, trace metals, physical properaties, nutrients, total organic carbon, oil and grease, trihalomethanes, and algal assay. Predictions were made as to the possible effects these coal mine accrual waters would have when used for drinking water, irrigation water, stock and …
