1.0 BACKGROUND
1.1 In recent years, planners, decision makers and the public have developed a deeper
understanding of the cumulative negative impact that ouruse of the land has on the
natural environment that sustains us. This has required a fundamental shift from a focus
on protecting individual natural features to protecting the entire natural heritage system
and its vital ecological functions. In turn, this has resulted in an increased emphasis on
incorporating consideration of the natural heritage system into all aspects of land use
planning, from official plan policies through to zoning and site plan and subdivision
approvals.
1.2 Watershed planning is currently recognized as one of the most effective mechanisms
for the protection, management and enhancement of the natural environment. It uses a
holistic approach to managing all aspects of a watershed's natural heritage system,
including hydrological resources (groundwater and surface water), terrestrial resources
(wildlife habitat and habitat connectivity), aquatic resources and habitat (e.g. fish,
streams, wetlands), and the inter-relationships that exist between these resources.
Watershed plans are also locally based and therefore reflect, and are responsive to, the
unique conditions including human land use,that exist within each watershed.
1.3 Both the Durham Region and the Clarington Official Plans include policies that
recognize the importance of watershed planning to the protection and wise
management of natural heritage resources, and support the preparation of multi-
stakeholderwatershed planning studies. The Regional Official Plan, as well as area
municipal official plans, require the inclusion of appropriate policies to implement
individual watershed plans.
1.4 In 2002, the provincial government, through the Oak Ridges Moraine Conservation Plan,
directed every upper-tier and single-tier municipality to prepare watershed plans for
every watershed whose streams originate on the Moraine. In response to this legislative
requirement, the Ganaraska Region Conservation Authority (GRCA), in partnership with
the Region of Durham, the Municipality of Clarington and other watershed municipalities,
has coordinated the preparation of watershed plans for Wilmot Creek, Graham Creek,
and the Ganaraska River. In order to provide complete watershed coverage in
Clarington, GRCA also prepared a joint watershed plan for three smaller watersheds
(Lovekin Creek, Bouchette Point Creek, and Port Granby Creek) that arise south of the
Oak Ridges Moraine on the Lake Iroquois Plain (see Attachment 1).
2.0 WATERSHED PLANNING PROCESS
2.1 The process for preparing a watershed plan involves eight steps, as follows:
Step 1: Scoping
Step 2: Characterization of the watershed system
Step 3: Setting goals, objectives and working targets
Step 4: Developing management alternatives
Step 5: Evaluating management alternatives
REPORT NO.: PSD-043-10 PAGE 3
Step 6: Selecting preferred management alternatives
Step 7: .Finalizing targets
Step 8: Developing implementation and monitoring plans.
2.2 Step 1 (Scoping) involves choosing a study area, identifying issues of concern and
information gaps, and creating a Terms of Reference for the study. Step 2
(Characterization of the Watershed) entails defining the historical and current conditions
of the study area (i.e. the watershed). GRCA completed the Scoping exercise and the
ABC (Abiotic, Biotic and Cultural) Background Reports for each of the four subject
watersheds in 2009. These background reports contain the scientific information and
local knowledge necessary for the preparation of the actual Watershed Plans (Steps 3
to 8 of the process).
2.3 A successful watershed planning process is, by necessity, a cooperative process that
involves a variety of governmental and non-governmental stakeholders. A Technical
Review Committee was created to provide technical assistance to Conservation
Authority staff in the preparation of the various watershed plans. Members on this
Committee included Clarington Planning staff, Durham Region Planning staff, the
federal Department of Fisheries and Oceans, and the provincial Ministries of the
Environment and Agriculture, and Food and Rural Affairs among others.
2.4 Community Advisory Committees were also formed, with membership drawn from
interested members of the local community. The role of these committees was to
promote awareness of the watershed planning process, to solicit broader public input on
issues within each watershed, and to comment on the recommended goals, objectives
and management actions in the watershed plans. Opportunities for public and
stakeholder input on the watershed studies occurred during 2009, including public open
houses in Orono, Newcastle Village and Port Hope.
3.0 OVERVIEW OF THE WATERSHED PLANS
3.1 The Watershed Plans divide the watersheds into eight separate components to facilitate
the presentation of information and the discussion of issues, as follows:
• Groundwater quantity
• Surface water quantity
• Groundwater quality
• Surface water quality
• Aquatic habitat and species
• Terrestrial natural heritage
• Public health and well-being
• Community heritage.
REPORT NO.: PSD-043-10 PAGE 4
3.2 Issues/Opportunities. Goals. Obiectives and Management Actions
3.2.1 The discussion of each watershed component was, in turn, divided into a number of
sub-categories, as discussed below.
3.2.2 Issues and Opportunities -These are current or future activities and conditions that
currently or could negatively impact the watershed. For example, an issue identified with
respect to Surface Water Quantity relates to the need to better understand natural flow
variations in the various watercourses in the watersheds.
3.2.3 Goal.- A goal statement was created for each watershed component to identify a
desired outcome to be achieved through the implementation of the watershed plan. For
example, the goal for Surtace Water is "Maintain and improve the hydrologic function of
the watershed".
3.2.4 Objectives -Objectives were created for each goal statement in order to facilitate and
achieve the desired goal for the watershed component. All issues and opportunities
identified in the Watershed Plan are addressed by the Objective statements. For
example, one of the objectives for Surface Water Quantity is "Maintain and enhance the
water balance and baseflow'".
3.2.5 Management Actions -Activities that need to occur were identified under each
Objective in order to achieve the goal of each watershed component. Management
actions are defined in four categories: Regulations and Planning, Stewardship,
Education and Awareness, and Land Acquisition. Monitoring and Reporting are also
listed as proposed management actions to assist in understanding how the
implementation of the recommendations in the Watershed Plans is influencing the
watersheds.
The management actions most relevant to the Municipality are those listed under
Regulations and Planning, which are primarily policies intended to be incorporated into
municipal, Conservation Authority and .other agency planning and regulations
documentation. To a lesser extent, some of the management actions listed under
Stewardship are also applicable to the Municipality -for example, encouraging the
adoption of urban land uses that increase groundwater recharge. As well, the
Municipality is involved with and supports the Clean Water Healthy Land Financial
Assistance Program, and GRCA's stewardship program.
3.2.6 For the most part, the same Goals, Objectives and Management Actions have been
identified in each Watershed Plan. These are summarized on Attachment 2 to this
report.

4.0 CONCLUSION
PAGE 5
4.1 The preparation of a Watershed Plan is only the first step in the ongoing process of
managing and protecting the resources and ecological functions of a watershed. In
order to be effective in achieving its stated goals and objectives, the management
actions recommended by the Watershed Plans need to be implemented by the various
stakeholders to the watershed planning process, including the Municipality of
Clarington. As well as provincial legislation, the policies in the Durham Region Official
Plan require the Municipality to incorporate appropriate policies into our Official Plan in
order to implement watershed plans.
4.2 It is therefore appropriate that the Watershed Plans for Wilmot Creek, Graham Creek,
Ganaraska River, and Lovekin, Bouchette Point and Port Granby Creeks be referred to
Staff for detailed consideration through the ongoing Clarington Official Plan review
process.
