Reports

Comprehensive planning is an elusive ideal. The practical planner must sort the relevant information from the vast amounts of data that modern technology can collect. The objective of this study was to use the Upper Blackfoot watershed in the mountains of Southeastern Idaho as an arena for developing methods for construction, refinement, and application of indices needed to design land and water management schemes, compare alternatives, and influence the public in their uses of the area. A total of 21 uses were examined on 242 land units of a 160 square-mile area ranging in elevation from 6300 to 9000 feet …


Reconnaissance Of Sediment-Phosphorus Relationships In Some Utah Reservoirs, Jay J. Messer, Jean M. Ihnat Jan 1983

Reconnaissance Of Sediment-Phosphorus Relationships In Some Utah Reservoirs, Jay J. Messer, Jean M. Ihnat

Reports

Introduction: Phosphorus inputs to lakes and reservoirs from tributary streams and non-point sources are well-known contributors to nuisance algal growths that degrade water quality for potable and recreational uses in lakes and reservoirs. However, phosphours inputs to the euphotic zone may also occur from within the lake itself, as a result of releases from both oxic and anoxid sediments. Such releases may originate from phosphorus inputs to a lake or reservoir during high runoff periods in the previous winder or spring, or they may represent phosphorus trapped in the sediment many years earlier, when phosphorus contributions from natural or anthropogenic …


Polycyclic Aromatic Hydrocarbons: Are They A Problem In Processed Oil Shales?, David L. Maase, V. Dean Adams Jan 1983

Polycyclic Aromatic Hydrocarbons: Are They A Problem In Processed Oil Shales?, David L. Maase, V. Dean Adams

Reports

Organic residues from processed oil shales were characterisized with specific attention to polycyclic aromatic hydrocarbons (PAH). Oil shale development in the White River Basin (Utah and Colorado) was projected and hydrological and geological parameters pertinent to estimations of polycyclic aromatic hydrocarbons (PAH) flux were focused. Oil shale samples from the Union B, Paraho, and Tosco II processes were extracted by using organic solvents in a soxhlet apparatus and by mixing shale samples with water (characterization in


Adapting Water Services To Urban Growth: A Case Study Of Salt Lake County, Dean T. Larson, Kirk R. Kimball, Calvin W. Hiibner, Jay M. Bagley Jan 1983

Adapting Water Services To Urban Growth: A Case Study Of Salt Lake County, Dean T. Larson, Kirk R. Kimball, Calvin W. Hiibner, Jay M. Bagley

Reports

Urbanizing areas thorughout the nation are considering governmental reorganization or consolidation to coordinate planning and improve the cost effectiveness of the delivery of public services. More efficient water supply and wastewater services may become important in the political debate over reorganization. However water factors figure politically, accomplished reorganizations must carefully plan for efficent provision of water services. This study profiles the structure and interactions of municipalities and water service agencies in Utah's Salt Lake County during the 1970s. Both 1975 and 1978 attempts to consolidate Salt Lake City and the unincorporated areas of the county failed. The voting patterns, interest …


Adapting Appropriation Water Law To Accommodate Equitable Consideration Of Instream Flow Uses, Jay M. Bagley, Dean T. Larson, Lee Kapaloski Jan 1983

Adapting Appropriation Water Law To Accommodate Equitable Consideration Of Instream Flow Uses, Jay M. Bagley, Dean T. Larson, Lee Kapaloski

Reports

The increasing public interest in naturally flowing streams has fostered efforts to obtain their protection under existing state water laws. In this study, the water laws of Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming were examined and compared 1) with each other, and 2) against a set of aleitn criteria, to assess shortcomings in accommodating instream flow protections. It was determined that the appropriation system has the essential features of and ambodies legal principles that should allow the accommodation of instream flow values but, at this time, purchase of existing rights or the exercise of governmental reservation/withdrawal/appropriation …


Impediments To Effective Interactions Between Multipurpose Water Districts And Other Governmental Institutions In Urbanizing Areas, Jay M. Bagley, Frank W. Haws, Wendell B. Anderson, Daniel H. Hoggan, Lee Kapaloski Jan 1983

Impediments To Effective Interactions Between Multipurpose Water Districts And Other Governmental Institutions In Urbanizing Areas, Jay M. Bagley, Frank W. Haws, Wendell B. Anderson, Daniel H. Hoggan, Lee Kapaloski

Reports

Water institutions are highly diffused throughout society. These institutions interact with one another in various ways. As water needs and services expand, collaborative and cooperative arrangements are commonly sought as a means of meeting common goals of providing a safe, dependable adn least cost water supply to particular constituencies. Of the many different institutions involved in the development, managment, distribution, and use of water, perhaps the most significant in terms of extensive interactions with other institutions is the kind that is typified by Water Conservancy Districts and Metropolitan Water Districts in Utah. The statutory and operating framework of counterpart organizations …

Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang Jul 1982

Analysis Of Organic N-Chloramines In Chlorinated Drinking Water, John Po Wen Yang

Chemistry & Biochemistry Theses & Dissertations

This thesis describes the development of a sensitive method for the separation and quantitation of organic N-chloramines in chlorinated tap water. 5-Dimethylaminonaphthalene- l-sulfinic acid has been synthesized and characterized. It yields highly fluorescent dansyl derivatives on reaction with N-chloramines. Conditions of the derivatization were optimized for the detection of N-chloropiperidine at concentrations in aqueous solution of 10-7 M. The technique gives a quantity of derivative which is proportional to the concentration of chloramine present over the range examined (10-7 M to 10-4 M). High pressure liquid chromatographic separation of dansyl derivatives of amines and amino acids has …

Migration Patterns For Age And Sex Classes Of Blackbirds And Starlings, Richard A. Dolbeer Mar 1982

Migration Patterns For Age And Sex Classes Of Blackbirds And Starlings, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Red-winged Blackbirds (Agelaius phoeniceus), Brown-headed Cowbirds (Molothrus ater), and Starlings (Sturnus vulgaris) are ubiquitous breeding birds in much of North America. The Common Grackle (Quiscalus quiscula) is an abundant breeding bird east of the Rocky Mountains (Dolbeer and Stehn 1979). Although these species are widely dispersed and generally unassociated during the nesting season, they often associated closely in winter roosts containing up to 10 million birds in the southern United States (Meanley and Webb 1965, Meanley 1971). Little is known about the comparative migration patterns of the four species and the resulting mixture of local breeding populations in winter. Comparative …


Effect Of Pellet Size And Packaged Commercial Baits For The Control Of Pine Voles, Ross E. Byers, Mark H. Merson Mar 1982

Effect Of Pellet Size And Packaged Commercial Baits For The Control Of Pine Voles, Ross E. Byers, Mark H. Merson

Eastern Pine and Meadow Vole Symposia

No difference in field control of pine voles was found be¬tween 3 different pellet sizes broadcast at either 5.6 kg/ha (5 lbs/.p acre) or 11.2 kg/ha (10 lbs/acre) for either Volid or ZP Rodent Bait . Comparison of the 18 Volid plots with the 18 ZP Rodent Bait plots showed a statistical difference in animal control between these materials of 95% and 85% respectively. Place packs of Volid or ZP Rodent Bait were opened at approximately 95% of the active sites. Since about 5% of the sites were active by the apple indexing, we believe a low but residual population …


A Current Assessment Of Vole Damage And Numbers And Of Methods Used To Control Voles In Ontario Apple Orchards, Ronald J. Brooks, Stephen A. Struger Mar 1982

A Current Assessment Of Vole Damage And Numbers And Of Methods Used To Control Voles In Ontario Apple Orchards, Ronald J. Brooks, Stephen A. Struger

Eastern Pine and Meadow Vole Symposia

A province-wide evaluation of the amount, distribution, source and control of damage to Ontario apple trees was initiated. Data we re obtained from 280 responses to a questionnaire distributed to growers across Ontario, and from trap censuses in three widely separated areas. Meadow voles (Microtus pennsylvanicus) damaged or destroyed 8,423 trees in our questionnaire sample and other mammals damaged another 10,307 trees. No relationship was found between application of rodenticide and levels of damage, but rodenticide-treated baits sharply reduced numbers of voles on our trap plots. Orchards with high levels of damage were on average only one-third as …


Long Term Vole Control In Ontario Apple Orchards, Zia Siddiqi, W. D. Blaine Mar 1982

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

Eastern Pine and Meadow Vole Symposia

A poisoned bait feeder station is being evaluated for a long term meadow vole control in Ontario apple orchards. This bait station can maintain a bait supply even under deep winter snow cover, commonly experienced in Ontario, when voles inflict extensive tree damage. Latest generation of acute anticoagulants, encapsulated zinc phosphide, and commercial formulation of zinc phosphide treated cracked corn bait in the bait stations are evaluated against the conventional broadcast application of the zinc phosphide treated cracked corn.

Rodenticide Evaluation In The Hudson Valley During 1980 And 1981, Paul F. Steblein, Milo E. Richmond

Eastern Pine and Meadow Vole Symposia

The objective of Cornell University's research program is to develop a successful integrated system to control pine and meadow vole damage in the apple orchards of the Hudson Valley. This is being accomplished by determining the effect of habitat manipulation and rodenticides on vole populations. We are also doing research to quantify the amount of damage apple trees sustain from various densities of pine voles. By coupling the results of these two avenues of research, we hope to provide growers with a cost-effective pest management plan. Efficacy of Chlorophacinone (Chempar, Inc.) and Brodificoum (ICI Americas, Inc.) in various populations and …


Orchard Rodent Baits: Toxicant Evaluations And Vole Pellet Size Preferences, Mark H. Merson, Ross E. Byers Mar 1982

Orchard Rodent Baits: Toxicant Evaluations And Vole Pellet Size Preferences, Mark H. Merson, Ross E. Byers

Eastern Pine and Meadow Vole Symposia

Residues of the anticoagulant rodenticide Brodifacoum in meadow voles (Microtus pennsylvanicus) sampled from an orchard popula¬tion after broadcast treatment with the commercial bait VOLID decreased as the orchard rate of application and concentration of Brodifacoum in the bait decreased. Oral LD— determinations for the experimental rodenticide EL-614 were 8.8 mg/kg for meadow voles and 24.0 mg/kg for pine voles (M. pinetorum) . No size preference by meadow and pine voles for bait pellets from 2.38 to 4.76 mm in diameter was observed in lab¬oratory tests.


The Relationship Of Nutritional Factors To Apple Tree Root Damage By Pine Voles, F. A. Servello, J. J. Hasbrouck, R. L. Kirkpatrick, K. E. Webb Mar 1982

The Relationship Of Nutritional Factors To Apple Tree Root Damage By Pine Voles, F. A. Servello, J. J. Hasbrouck, R. L. Kirkpatrick, K. E. Webb

Eastern Pine and Meadow Vole Symposia

Damage to apple tree roots by pine voles is believed to occur primarily during the winter months. Cengel et a1. (1978) found that the stomachs of pine voles contained significant amounts of root material only during January and March sampling periods. In addition, the diet of pine voles at that time consisted primarily of less preferred grass species because preferred forb species were unavailable. Therefore, apple tree roots may serve as a food source in the winter when preferred forages are unavailable. If, in fact, pine voles are consuming roots in response to reduced food supplies, then one would expect …
