Aquatic Resource Management Plans

It has long been recognized that agricultural and urban land uses have a strong tendency to degrade biological diversity within streams. Widespread urbanization and the associated effects of storm water runoff, stream channelization and elimination, water pollution, and water contamination have been reported as significant threats to stream health in the Great Lakes area. Consequently, watershed managers have a responsibility to assess and monitor stream health, so that future watershed development can proceed in the best environmental manner possible.

Aquatic Resource Management Plans (ARMPs) address this challenge and provide an approach to guiding land use planning, stewardship and aquatic monitoring within CLOCA watersheds to maintain and enhance the aquatic system. Three ARMPs have been completed to date, for Oshawa Creek, Bowmanville/Soper Creeks and Lynde Creek. The ARMP for Black, Harmony and Farewell Creeks is underway and scheduled for release in the spring of 2007.

Goals and Objectives

Each ARMP is completed within the framework of the following Goals and Objectives:


  1. Maintain and enhance healthy, self-sustaining aquatic ecosystems in the watershed.
  2. Establish a Management Plan at a watershed level in accordance with Municipal, Regional, Provincial, Federal, and International directives, policies, or initiatives.
  3. Develop recommendations for future policies for the protection of fish habitat and as a guide for land use planning.
  4. Support integrated resource management throughout the watershed.
  5. Follow an established framework for aquatic resource management within the CLOCA jurisdiction to provide a consistent, quality product.
  6. Identify opportunities for resource restoration and enhancement within the watershed.
  7. Identify and support opportunities for public and private stewardship within the watershed.


    Historical Conditions

  1. Determine the historical land uses and fish communities of the watershed.
  2. Identify trends and reasons for trends in aquatic communities within the watershed.
  3. Existing Conditions

  4. Identify assessment needs to determine the health of the watershed.
  5. Assess the present condition of aquatic communities within the watershed.
  6. Identify current pressures on aquatic ecosystems and the watershed response.
  7. Resource Management

  8. Determine current land uses within the watershed.
  9. Delineate management zones for all reaches within the watershed.
  10. Provide management options and recommendations for all management zones.
  11. Develop strategies for the management of native and non-native species.
  12. Investigate the comments and concerns of the public and special interest groups.
  13. Encourage balanced resource use.
  14. Develop and support a strategy for restoration and enhancement of aquatic, riparian, and wetland habitats within the watershed.
  15. Develop a watershed monitoring and assessment program to facilitate adaptive management of the watershed.
  16. Develop an education and communication strategy for watershed stewardship.
