Book excerpt: Smallmouth bass were studied in Bull Shoals Lake to determine the nesting requirements and reproductive capabilities of the species in a reservoir. Underwater observations were conducted weekly in five study areas during the spawning seasons of 1969-76. Length of spawning season was affected by the rate of water temperature rise during the nesting period. Active nests were found at ambient temperatures of 13.3-22.5 degrees Centigrade. Nest were generally on gently sloping rock and gravel bottoms, beside permanent objects such as rocks or sunken logs, and at densities of less than one per 100 m of shoreline.
