Three major occurrences in recent years have emphasized a need for new data concerning reservoir-based recreation patterns. These occurrences were: (1) the increased rate of construction of new, large reservoirs by federal agencies; (2) the increasing demand for recreation space and fishing water; and (3) the establishment of large national recreation areas around federal reservoirs.

Sediment resuspension due to the operation of recreational motorboats in shallow lakes was investigated. Boats equipped with 28, 50, 85, 120, and 165 horsepower engines were used for this study on Lake Claire, Florida Technological University campus, and Lake Mizell, the City of Winter Park, located in Orange County, Central Florida. Grasshopper Lake was also a test site due to its clarity for underwater photography. These motorboats were run at different speeds and water depths and the induced pressure waves on the lake bottom were measured using a hydrophone and recording system. Primary and secondary wave amplitudes and frequencies were determined for the various operating conditions and motorboats. The primary waves were formed by boat wake and the secondary waves resulted from engine effects. The primary waves were generally higher in amplitude and lower in frequency than the secondary waves. The maximum amplitudes occurred just before planing. The average primary wave amplitude after planing at normal operating speeds decreased exponentially with increasing water depth for all the boats tested and followed this equation: Aw = ae-bD where: Aw = average primary wave amplitude, ft. a = constant varied between boats = 0.68 to 1.86 ft. for boats tested b = 0.17 to 0.25 ft-1 D = water depth, ft The boat waves resuspended bottom sediments and eroded shore areas, increasing the turbidity of the lake water. Particle count and size distribution in water samples were determined using a Coulter Counter. A straight line relationship between turbidity and cummulative particle count per milliliter existed on a semi-log graph. Calculated and measured bottom water velocities showed good agreement for a limited amount of data.

The primary objective of this research was to examine knowledge levels of low-impact recreational practices and to explore the effectiveness of education in reducing impacting behavior among users of Shining Rock Wilderness. Wilderness users were found to have little low-impact knowledge, scoring only 59.7 percent correct on a 10-item multiple choice test. Knowledge of recommended practices regarding campsite selection, one of the most important low-impact behaviors, was much lower at 32.9 percent correct. These low scores are likely due to evolving agency low-impact recommendations and the complexity of the task regarding proper campsite selection behavior. Wilderness users had a moderately strong positive correlation between knowledge of campsite selection recommendations and intentions to select a wilderness campsite. The relationship between knowledge and and actual behavior observed in the wilderness and intentions and behavior appeared to be positive, but conclusions were limited by the small number of field observations. Posters on proper campsite selection, tent placement, and use of backpack stoves rather than campfires were placed on trailhead signs to increase knowledge, foster appropriate intentions, and improve actual behavior. A field experiment with a control group (e.g., no educational posters) showed that the trailhead posters had little positive effect on knowledge or intentions, improving only one of the five tested knowledge items and one of the three behavioral intentions. The posters improved fire building behavior, but not tent placement or campsite selection. Trailhead posters seem to be more effective at improving behaviors that do not require complex judgments about campsite impacts and wilderness use levels. / Master of Science
