| Abstract |
The primary objective of this project was to assess the state of the water quality of Harding Lake, and to attempt to predict the effects of future development within its watershed. Since the major effect of degradation of water quality due to human activity is the promotion of nuisance growths of plants, the major emphasis was placed on measurements of plant growth and concentrations of the major nutrients they require. Planktonic algal growth was found to be low, below 95.6 gm/sq m/year, and the growth of submerged rooted plants was found to be relatively less important at approximately 1.35 gm/sq m/year. A model for predicting the effect of future real estate development in the watershed was modified and applied to this lake. This model adequately describes current water quality conditions. A secondary objective was to study the thermal regime of a deep subarctic lake. Hydrologic and energy budgets of this lake are given. Limited work on the zooplankton, fishes and benthic macroinvertebrates of this lake is also presented. |
