Title: Kawartha Lakes - Trent River water management study field methodology
Author: Michalski, M. F. P.
Abstract: In 1971 scientists of the Ministries of the Environment and Natural Resources and co-operating universities began a study of the Kawartha Lakes system between Balsam Lake and the Bay of Quinte. The broad objective is to develop a sound water management plan to optimize water use potential. As such, the study will take cognizance of all human, social and economic factors which influence the pattern of water resource utilization throughout the system. As part of the study, scientists are considering the possibility of removing excessive weed growths with aquatic weed harvesters to improve the potential of a lake to support activities such as swimming, boating, water skiing and yachting. As indicated earlier, it is also possible that such a harvesting programme would create a "nutrient-drain" by the repetitive cropping and removal of plant materials from overly-enriched waters. However, before moving too far in this direction it is imperative to determine what effects weed harvesting will have on the fisheries of a lake. It is entirely possible that large areas of aquatic plants may be removed without damaging fish production and also, that a specific pattern of cutting may actually enhance the fishery. On the other hand, adverse effects might result. During the summer of 1972 biologists of the Ministries of the Environment and Natural Resources will carry out intensive studies on Lake Chemung to assess biotic relationships in both weedy and adjacent cleared areas, as well as evaluating angling success prior to possible experimental harvesting throughout a significant portion of the lake.
