The years after World War II also signaled the end of agriculture as a principal use of the watershed land and the rapid residential development in the hills of Richmond and Canadice overlooking the lake. The reduction of agriculture resulted in the natural re-forestation of inactive agricultural lands, which was beneficial in reducing erosion. However, increased residential development resulted in the loss of native vegetation and an increase in impermeable surfaces. These historical changes in the watershed have impacted the watershed character and the water quality— both for better and worse.
