Pre-Impoundment Estimations of Nutrient Loading to Ray Roberts Lake and Prediction of Post-Inundation Trophic Status

Description: Excessive nutrient loading of natural and artificial lakes has led, in some systems, to plethoric algal and aquatic macrophyte growth which can result in aesthetic degradation and undesirable tastes and odors. It would be advantageous to have some indication of the potential trophic status of a reservoir before it is filled. An objective of this study was to assess the water quality and nutrient loading potential of the tributaries entering Ray Roberts Lake, a large reservoir located in north central Texas. Samples from a maximum of thirteen sites were collected on the Elm Fork, Trinity River, Isle duBois Creek, and five additional tributaries. Data were also collected during six storms, from atmospheric deposition collectors, and from soil-water microcosms. The relationship between watershed landuse and mean water nutrient concentrations was evaluated. Significant differences will exist between the two major arms of Ray Roberts Lake: Elm Fork, Trinity River and Isle duBois Creek. While the majority of the annual phosphorus and nitrogen load entering both tributaries is coming from overland flow, the proportion is higher in Isle duBois Creek. Point sources in the Elm Fork contribute a larger percentage of the bioavailable phosphorus, which is significantly greater than in Isle duBois Creek. The water quality of Isle duBois Creek, especially nitrogen, is affected to a greater degree by the landuses in its watershed. Predictive regression models made accurate estimations of stream nutrient concentrations in Isle duBois Creek. The entire reservoir, upon reaching equilibrium conditions, will be classified as a eutrophic lake. The Trinity arm, with a higher phosphorus load, will display a higher trophic status. The Isle duBois arm has a lower phosphorus load which will give it a lower trophic status. The long hydraulic residence time of the two arms of the reservoir will remove nutrients upstream of the main body, …

Electricity in Rural Areas of North Texas

Description: "This study shows three things: (1) a precedent for the expenditure of public funds to teach electricity in our public high schools has already been established by the school system in the larger school systems of Texas, (2) the rural families living on electrified farms in the North Texas area want instruction of this type given to the boys and girls in their communities, and (3) both the rural people and the professional people of the North Texas area believe that instruction dealing with the use of electricity and electrical equipment had spread until by 1935 more than twenty-one million homes, about eighty percent of the total in America at that time, were electrified, only eleven American farms out of every 100 had central-station electricity. More than five million American farms lacked electric service. "--leaf 50.

Some Morphological Aspects of the Speech of Cooke County, Texas

Description: A survey of language in a certain area is designed primarily to present a living language as it is actually spoken; thus, a morphological study of language is designed to determine the most widely-used syntactical and grammatical forms and to record these forms in a statistical manner. These findings are to be interpreted in the light of similar studies, not with the purpose of establishing the cultural level of the language in the area surveyed, but to present all the possible variations, and, in some cases, to draw a comparison as a matter of record between the forms found to be commonly used in every-day speech and the standard usage as given by leading linguistic authorities.

Posttraumatic Stress Disorder in Adolescents with Conduct Disorder: Pre- and Post-Treatment Comparison of Trauma Types

Description: The purpose of this study was to compare pre- and post-treatment differences in posttraumatic stress disorder (PTSD) symptoms in male adolescents with conduct disorder. The Children's PTSD Inventory and the PTSD Reaction Index were used to diagnose PTSD and determine trauma type (Type I single trauma or Type II recurring trauma). Pre- and post-treatment measures included the PTSD Reaction Index, the Children's Depression Inventory, the State-Trait Anxiety Inventory, the State-Trait Anger Expression Inventory, the Dissociative Experiences Scale, and the Youth Self-Report. The six-week, biweekly group treatment included education, exposure, and cognitive elements. Primary hypotheses that the abused group would statistically differ from the non-abused group in terms of pre- and post-treatment levels of avoidance, dissociation, anger/aggression, self-destructiveness, social problems, and overall levels of PTSD symptoms, were not confirmed. Overall, group therapy participants experienced statistically significant decreases in PTSD symptoms over the course of therapy. Results are discussed in light of clinical implications, recommended cautions given the lack of a robust control group, and directions for future research.

A Comparison of Predicted and Actual Trophic Status of Lake Ray Roberts, Texas Based on Chlorophyll A

Description: Two years before impoundment, the trophic status of Lake Ray Roberts was predicted by applying the total phosphorus input into the Organization for Economic Cooperation and Development (OECD) eutrophication model. Predicted mean summer epilimnetic (MSE) chlorophyll a of Elm Fork arm, Isle duBois arm and Main Body were in the eutrophic category of the OECD model. Observed MSE chlorophyll a two years after impoundment of Elm Fork arm, Isle duBois and Main Body had not reached their predicted means and were at the mesotrophic-eutrophic boundary of the OECD model. Six years after impoundment, observed MSE chlorophyll a for Main Body, was closer to its predicted mean and in the eutrophic category of the OECD model. Six years after impoundment, Elm Fork arm was the most productive area of Lake Ray Roberts. Observed means of chlorophyll a, total phosphates, suspended solids and turbidity were often highest in the Elm Fork arm. Wastewater effluent from Gainesville and Valley View, TX, had an impact on productivity in Elm Fork arm.

A Survey of Landowner Attitudes Toward the Construction of Lake Ray Roberts

Description: 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.
