AbstractThe Source Water Protection (SWP) Program, with the purpose of protecting the surface or groundwater that supplies municipal drinking water systems, has been managing the development of water resources numerical models at various conservation authorities (CAs). For the Central Lake Ontario Conservation Authority (CLCOA), groundwater models have been developed to support work under Oak Ridges Moraine Conservation Plan (2001), the Clean Water Act (2006) and CLOCA's watershed management program. CLOCA analyzed each dataset and grid results for optimum use in source protection as well as other CA programs. The grid results were used to calculate water balance for various purposes such as watershed management planning, development plan reviews, and opportunities for low impact developments. Reverse particle tracking path lines provided information to identify the natural and ecological features that could potentially be impacted by proposed developments and/or land use changes. Other vital grids and theme maps utilized include, but are not limited to, groundwater discharge to streams, ecologically significant groundwater recharge areas and highly vulnerable aquifers.
In the absence of wellhead protection areas (WHPA) within its jurisdiction, CLOCA has determined that the numerical model development instituted under the SWP Program has more utility for purposes beyond the initial objective of the program. The numerical model products serve as additional science-based planning tools that are defensible for CA to manage and protect the water resources within its watershed.
