Date of Defense 1987-05-15 Availability restricted AbstractA limnological survey of Lake Laura and its tributary streams
was conducted from June to October 1986 to evaluate causes of
excessive algal blooms experienced in past years.
Lake Laura was classified as mesotrophic based upon total
phosphorus surface water, chlorophyll g, and secchi disc levels
measured. Due to atypical meteorological conditions experienced
during the study, the Vollenwieder model was utilized to evaluate the
impact of various nutrient sources on Lake Laura under more typical
conditions. Nonpoint source runoff from agricultural and pasture
land and effluent from the Orkney Springs waste water treatment plant were determined to be the main sources of nutrient inputs to Lake
A description of lake and drainage basin monitoring methods,
model results, and an analysis of recommended lake management
practices to control future algal blooms is included.
