Assimilative Capacity Study

Assimilative capacity is the relationship between water quality and quantity, land use, and the capability of the watercourse or lake, to resist the effects of landscape disturbance without impairment of water quality. An assimilative capacity study (ACS) develops specific scientific modelling to support and assist municipalities and other legislative authorities in predicting the impacts of land use.

The ACS aims to conserve the natural resources of Lake Simcoe and the Nottawasaga River in a cooperative, integrated manner that balances human needs with those of a sustainable natural environment. Combined efforts will ensure a safe drinking water supply, a healthy aquatic ecosystem and stream, increased recreational opportunities, sustainable agricultural operations, and a vibrant economy.
