Abstract
A 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

Laura.

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.
