Source Water Protection and Environmental Farm Plans

Source Water Protection is a function of the Government of Ontario’s Clean Water Act, which seeks to ensure clean, safe and sustainable drinking water for Ontarians through the protection of municipal drinking water sources. Under this legislation, regions of surface or ground water that supply municipal drinking water systems are identified and methodically protected through the creation of Source Protection Plans. This represents only one aspect of a multi-barrier approach to ensure that Ontario drinking water is among the best protected in the world.

Visit Conservation Ontario to learn more about Source Water Protection in the Lake Huron watershed.

Lake Huron Watershed Source Water Protection Plans

The Source Protection Plans below explain source protection procedures for the following Lake Huron basin Source Protection Regions (SPRs) and Source Protection Areas (SPAs):

  • Ausable Bayfield Maitland Valley SPR
    • Ausable Bayfield Source Protection Plan
    • Maitland Valley Source Protection Plan
  • Saugeen, Grey Sauble, Northern Bruce Peninsula SPR (includes the Saugeen Valley SPA, Grey Sauble SPA, and Northern Bruce Peninsula SPA)
  • Sault Ste. Marie SPR
  • South Georgian Bay – Lake Simco SPR (includes the Lakes Simcoe and Couchiching/Black River SPA, Nottawasaga Valley SPA, and Severn Sound SPA)
  • Sudbury SPA
  • Thames-Sydenham and St. Clair Region SPR (includes the Lower Thames Valley SPA, St. Clair Region SPA, and Upper Thames River SPA)

Water Levels

Changing water levels are of particular interest to those living along the shoreline. Depending on one’s location within the watershed, high water levels can bring greater access to nearshore areas, revive coastal wetlands and enhance various recreational activities. Contrastingly, high water levels can be a cause of concern when associated other factors, such as storms, due to potential flooding and erosion problems.

The same variation is true for lower lake levels. In some areas of the watershed, lower lake levels might pose safety concerns for boaters, increased costs for commercial ships carrying lighter loads, wetland loss, and generate water quality concerns. Other shoreline users might relish lower water levels for reduced shoreline erosion and safety from storms and wave action.

Access the following resources to learn more about past, present and possible future water levels.

  • Georgian Bay Association
    The Georgian Bay Association provides information on Lake Huron water levels including two videos from CBC and CNN.
  • Great Lakes Information Network
    Access current water level information from 11 real-time water level gauging stations spread throughout Lake Huron.
  • Great Lakes Water Level Dashboard
    Consult NOAA’s historic record of Great Lakes water dating back nearly 100 years.
  • 2012 Upper Great Lakes Water Levels Study
    • Summary Report
    • Technical Report
  • Water Levels and Related Great Lakes Data
    Learn about historical, recent and current Great Lakes water levels and associated causes that are influencing water level changes.

Watershed Report Cards

Many watersheds within the greater Lake Huron watershed develop and publish watershed report cards. The reports provide a general description of the health of the watershed’s lakes, watercourses and forests using a letter grade ranging from A to F. This establishes effective and transparent communication of waterbed-based environmental monitoring and public reporting.

Access the links below to view the various watershed reports cards generated by Lake Huron conservation authorities and environmental organizations:

Introduction & Summit Summary


Introduction & Summit Summary

The Summit provided an opportunity to showcase the talents and achievements of some of the community-based organizations within our watershed and provide practical ideas and approaches to help turn community interest into environmental action.

Building Awareness & Capacity

Provides opportunities to increase knowledge, integrate scientific based, traditional and local knowledge, and by providing tools to improve skills and capacity.

Supporting Community Involvement

Engaging the community in a collaborative process so that networks are formed and strengthened over time. Similar to other emerging philosophies and charters, we encourage people and groups to sign the Framework Charter.

Taking Action to Restore & Protect

Using scientific research and information, local and traditional knowledge to better understand local issues and to take action to protect unique and vulnerable ecosystems and restore degraded areas around Lake Huron.

Measuring Success & Adapting

Identifying performance indicators, measuring the success of projects and programs, and reporting the results and achievements in a public friendly manner to learn and improve future approaches.
