Documentation of social impacts resulting from the construction of Lake Ray Roberts is to be incorporated into a two year post-impoundment study. Research objectives are to: 1) locate current residences of landowners and previous landowners who were displaced; 2) determine social impacts resulting from construction of Lake Ray Roberts; 3) document degree of satisfaction with current living conditions; 4) document landowners' degree of satisfaction associated with COE negotiations; 5) document landowners' observations. Landowners were identified by telephone and sent a mail-back questionnaire. Respondents were generally happy with current residences and communities. While courtesy and sufficient information were provided by the COE, respondents would have preferred for property settlements to be more consistent and timely.

A total of 192 largemouth bass were caught at Lake Ray Roberts, Texas (1995) to investigate five controversial bass angling techniques relative to hooking mortality. The bait types were Texas-rigged scented and non-scented plastic worms, Carolina-rigged scented and non-scented plastic worms, and live golden shiners. Overall hooking mortality was 21.87% and mortality was dependent upon bait type. Highest mortality resulted from the Texas-rigged scented lures, while the lowest mortality was generated by live golden shiners. A creel survey indicated that few anglers were having success with the investigated baits. Factors that had a confirmed effect on hooking mortality were hooking location and water temperature. Hooking mortality was not excessive compared to other similar studies.

This study focused on the effectiveness of integrating traditional plant community analyses with landscape ecological analyses based on remotely sensed data. A temporal analysis of plant community diversity was conducted for major plant communities of the Ray Roberts Lake area using transect monitoring data collected between 1987 and 1997. Landscape analyses were performed with FRAGSTATS*ARC using classified SPOT satellite imagery for 1987 and 1997. Although the methodology developed in this work was exploratory, it was found that characterizing the dynamics of major plant communities in the study area produced a more effective and insightful analysis of Ray Roberts Lake area landscape dynamics.

The purpose of this thesis was to investigate the following hypothesis: "that Benefit-Cost analysis is a suitable and sufficient technique for the allocation of waterfront to competing uses." The greatest stress is placed on the technique by limiting the meaning of "allocation" to problems involving mutually exclusive uses which compete for the same waterfront site. In this context choice of the best from a number of suitable sites for a use or of the most efficient scale of a project on a site are not considered to be allocation problems. Chapter I defines the waterfront and its elements— the shoreline, foreshore, and adjacent water areas—and discusses its major uses, extent, interrelationships, and multiple-use potential. Also discussed is the historical importance of the waterfront and some public attitudes which have fostered careless waterfront allocation and use. Thus, the need for comprehensive waterfront allocation procedures is established. The second Chapter briefly reviews Benefit-Cost theory and methods and discusses some problems of application. While acknowledging the extensive theoretical debate concerning the technique, it is outlined as it is currently-used in water-resource development programmes. Chapter III applies Benefit-Cost analysis to a specific waterfront allocation problem involving partly real-partly hypothetical port and recreation development proposals for the same site. Benefits, costs, and benefit-cost ratios are estimated for each of the two alternatives. Then basic assumptions with respect to the availability of other sites, the evaluation context, and timing are varied to examine the effects on the relative benefit-cost ratings of the two proposals. Problems of intangibles and of providing the necessary background for analysis are also discussed. The final Chapter summarizes the major conclusions regarding the utility of Benefit-Cost analysis in waterfront use decisions. It was concluded that the ratios for alternatives may shift substantially with changes in the context or viewpoint, with important implications for the distribution of benefits and costs amongst individuals, groups, and regions. Changes in timing also seriously affect relative ratings; it was found that the technique was not well-suited to long-range planning problems because of its orientation to specific projects. Finally, it was observed that the difficult type of allocation problem posed in this paper could create numerous intangible benefits and costs which, though considered to be of substantial importance, could not be integrated into the benefit-cost ratio in a useful way. Thus fundamental problems not encompassed by Benefit-Cost analysis must be solved before the ratios become useful for allocation purposes. It was concluded that the hypothesis was invalid. Instead, a comprehensive waterfront planning framework is suggested in which the role of Benefit-Cost analysis is seen to lie in investigating the welfare distribution consequences of alternative development proposals, in the efficiency of various scales of development of a facility or site, or in determining the best of the suitable alternative sites for a particular waterfront use. In this view Benefit-Cost analysis is thus accorded a more limited but still useful role. / Applied Science, Faculty of / Community and Regional Planning (SCARP), School of / Graduate

The objective of this research was to determine if physical and microbial sediment characterizations could be used to explain benthic macroinvertebrate distribution in two branches of Lake Ray Roberts, Texas.
