In the Rideau Canal Waterway, residents are required to obtain permits from Parks Canada for macrophyte removal in front of their property for recreational purposes. This thesis aims to determine the strongest environmental predictors of permit number and density in the Rideau Waterway to promote sustainable management of this system. Multiple linear regression models indicated that the best predictors of permit number were percent crop and pasture in the catchment, Secchi depth, algal blooms, catchment area, and total phosphorus (adjusted R2 value of 0.94 and p-value of 1.952e-05). The strongest predictors of permit density are percent crop and pasture, deviation from circle, status of lakes, chloride, catchment area, and catchment to lake volume (adjusted R2 value of 0.779 and p-value of 0.006). The results of this thesis indicate that macrophyte removal permits are issued most often in nutrient rich lakes with greater crop and pasture in their catchments.
