CARRUTHERS CREEK WATERSHED PLAN

PREPARING FOR THE FUTURE

Toronto and Region Conservation Authority (TRCA), in partnership with the Region of Durham, is undertaking an update to the last Watershed Plan for Carruthers Creek, which was completed in 2003.

As we strive to develop a comprehensive watershed plan for the Carruthers Creek watershed, TRCA acknowledges that this watershed planning was undertaken within the traditional territory and treaty lands of the Anishinaabeg of the Williams Treaty First Nations, and the traditional territory of the Huron-Wendat Nation. As stewards of land and water resources within the Greater Toronto Region, TRCA appreciates and recognizes the history and diversity of the land, as well as our shared values and interests and is respectful of working in this territory.

Why do we need an update?

TRCA will assess changes and impacts which have occurred since 2003 and review the current conditions of the watershed. We will recommend actions to keep the watershed healthy over the long-term.

The new Plan will guide future decision-making for the watershed by the Region of Durham, the City of Pickering, the Town of Ajax, TRCA, and watershed residents, neighbours, businesses, and other stakeholders. Watershed Plans do not make decisions about land use.

How do you create a Watershed Plan?

TRCA will revisit the Vision and Management Philosophy established for Carruthers Creek watershed in 2003 as a foundation for the new Plan.

Scientists working on the Watershed Plan assess the watershed's current conditions by studying various features and functions including groundwater, geology, plants and animals, water quality, and the movement and changes in the stream over time.

Our scientific work will be reviewed by independent experts in each field, to ensure we relied on the best available science and our work is impartial and rigorous.

The resulting Watershed Plan will make recommendations for the protection, restoration, enhancement, and overall management of the watershed over the long-term.

  • A New Vision

    6 months ago

    As discussed in an earlier blog post, one of the main objectives of consultation during Phase 2, Stage 1 was to create a new vision statement for the Carruthers Creek Watershed Plan by gathering feedback on the vision statement from the 2003 Watershed Plan for Carruthers Creek.

    Generally, the feedback received on the 2003 Watershed Vision is that it is a good statement and remains relevant. When asked about what the public would like the New Vision to say, some responses were:

    As discussed in an earlier blog post, one of the main objectives of consultation during Phase 2, Stage 1 was to create a new vision statement for the Carruthers Creek Watershed Plan by gathering feedback on the vision statement from the 2003 Watershed Plan for Carruthers Creek.

    Generally, the feedback received on the 2003 Watershed Vision is that it is a good statement and remains relevant. When asked about what the public would like the New Vision to say, some responses were:


    “The essence of the (2003) Vision is on the mark. Enhance and protect the Carruthers Creek Watershed to ensure that it continues to provide valuable environmental and societal benefits to the community.”

    - Watershed Resident


    “The Vision needs to emphasize sustainability, climate change and biodiversity and retrofitting existing areas. The importance of continued research and science are important to acknowledge.”

    - Environmental Stakeholder


    There is a desire to update the Vision with current language and to incorporate new concepts and approaches. It was also noted that a succinct statement would make it easier to be understood and recalled by residents and stakeholders. The following ideas were frequently suggested for inclusion in the New Vision:

    • Incorporate resiliency and adaptation to climate change.
    • Have more focus on biodiversity and improving ecological health and integrity through a systems management approach.
    • Incorporate more emphasis on sustainability, restoration and retrofitting existing urban areas.
    • Highlight the importance of continued research and science.
    • More focus on health benefits of nature not just the risk versus benefit.
    • Encourage all stakeholders to participate in the stewardship of the watershed.
    After incorporating all feedback from various stakeholders, the New Vision now reads:

    Carruthers Creek watershed is a healthy and resilient natural system that is managed through partnerships to balance resource protection with human activity. Sound science and best management practices will protect and restore ecosystem functions, protect watershed residents from natural hazards like flooding, and maintain our natural heritage and water resources for present and future generations.


    TRCA and Region of Durham would like to sincerely thank all of the community members, stakeholders, and municipal staff who have dedicated their time to provide feedback to develop this New Vision for the Carruthers Creek Watershed Plan.

The Communications and Consultation Strategy was received by Durham Regional Council in May 2018, and time lines were refined at Council’s request in June 2018.

    Phase 2, Stage 1 began in December 2017 and was completed in October 2018. The Carruthers Creek Watershed Plan: Communications and Consultation Summary (Phase 2, Stage1) was created to outline the objectives which guided the communications and consultation and describes the methods and activities used to inform and consult the public and stakeholders. It also describes what was heard and how public input is reflected in the new Vision Statement and ongoing Phase 2 work. The summary report is now available in our Reports and Resources library.

    Figure 1: Over 600 residents were engaged at seven pop-Up events across Pickering and Ajax. The pop-up events were interactive and designed to gather feedback about the CCWP process and Vision statement.


    The consultation for Phase 2, Stage 1 had three (3) main objectives:

    1. Raise awareness about the Carruthers Creek Watershed Plan.
    2. Inform partners, stakeholders, and the general public about the process for updating the Watershed Plan.
    3. Gather feedback on the Vision developed for the 2003 Watershed Plan and preliminary issues and ideas to be considered in all the Phase 2 work.

    Figure 2: Thousands of public comments were received at pop-up events, presentations, stakeholder workshops, through the CCWP Website, and as part of an online survey.


    During this initial stage, consultation was undertaken to seek input on a new Vision Statement for the Watershed Plan. The new Vision Statement will be highlighted in a future blog post. Consultation will also be undertaken in subsequent stages to solicit feedback on the draft Management Recommendations (Stage 2) and draft Watershed Plan (Stage 3).

  • Carruthers Creek Watershed Plan: Fluvial Geomorphology Assessment

    9 months ago
    Img 20150605 100636

    This week's post will highlight the results of the Fluvial Geomorphology Assessment completed for the Carruthers Creek Watershed Plan.

    What is Fluvial Geomorphology?

    Fluvial geomorphology is the study of the form and function of streams and the interaction between streams and the landscape around them. ‘Fluvial’ refers to the processes associated with running waters, ‘geo’ refers to earth and ‘morphology’ refers to channel shape. Stream morphology is dynamic and constantly changing in both space and time. A stable stream channel is in a state of equilibrium and responds physically to the streamflow and sediment it receives from upstream.

    This week's post will highlight the results of the Fluvial Geomorphology Assessment completed for the Carruthers Creek Watershed Plan.

    What is Fluvial Geomorphology?

    Fluvial geomorphology is the study of the form and function of streams and the interaction between streams and the landscape around them. ‘Fluvial’ refers to the processes associated with running waters, ‘geo’ refers to earth and ‘morphology’ refers to channel shape. Stream morphology is dynamic and constantly changing in both space and time. A stable stream channel is in a state of equilibrium and responds physically to the streamflow and sediment it receives from upstream.

    Fluvial Geomorphology of Carruthers Creek

    This report characterized the channel morphology (the rate and locations of the movement of stream channels) in Carruthers Creek since the 2003 watershed plan was completed. Characterizing the channel morphology of a watershed is important because the physical form and function of a watercourse are key elements of aquatic habitat. Furthermore, establishing baseline conditions enables watershed managers to assess potential impacts from changes to the watershed.

    Methodology

    Following the completion of the 2003 watershed plan for Carruthers Creek, TRCA established the Regional Watershed Monitoring Program (RWMP). Under this program, Matrix Solutions Inc. established ten (10) monitoring stations along Carruthers Creek which were updated every three (3) years from 2003-2012. For this assessment, Matrix Solutions Inc. completed an updated desktop assessment (using aerial imagery) and data collected from the RWMP during detailed site visits in 2016 at all ten (10) monitoring stations. The report contains an anlysis of the full monitoring datasets from 2003, 2006, 2009, 2012, and 2016.

    Results

    Overall, the 13-year monitoring period provided a unique opportunity to document changes in channel morphology for the purposes of understanding channel processes. The assessment indicates that Carruthers Creek is an active channel, whether the cross-section is enlarging, aggrading, or continually adjusting while maintaining a similar size. Sites on the smaller tributaries of the creek suggest that channel dimensions are increasing. Comparatively, while the main branch sites exhibit active channel processes, overall change was minimal. This indicates the larger channel's resilience to changes in the surrounding area.


    Conclusion

    The information collected as part of this assessment will be used during Phase 2 of the watershed planning process to make recommendations for management of the natural heritage system and watercourses. To read the full Fluvial Geomorphology Assessment, please click here.

  • Carruthers Creek Watershed Plan: Terrestrial Biological Inventory and Assessment

    The inventories found 173 different ELC vegetation community types including 47 different natural forest communities, 22 plantations, 23 successional communities, 15 wetlands, 13 aquatic communities, 14 dynamic communities (e.g. savannah, beaches, bluffs), and 3 meadow types.

    Flora

    A total of 935 species of vascular plants were recorded including 845 naturally-occurring species. Of the naturally-occurring plants, 484 (57%) are native and 361 (43%) are non-native. Four (4) of the 153 flora species of regional conservation concern have not been found anywhere else in TRCA's jurisdiction. All four species are associated with wetlands and include sessile-fruited arrowhead, few-flowered spike rush, swamp rose, and shore horsetail. Carruthers Creek watershed has significant infestations of invasive exotic plants such as dog-strangling vine, garlic mustard, and common buckthorn.

    Figure 1: Swamp Rose (Rosa palustris) was found in the Carruthers Creek watershed in 2015

    Figure 2: Sessile-fruited arrow-head (Sagittaria rigida) was found in Carruthers Marsh at the mouth of Carruthers Creek.


    Fauna

    Inventories documented a total of 133 possible breeding vertebrate fauna species over the past decade. This total is composed of 106 breeding birds, 18 mammals, and 9 herpetofauna. Of note is a small colony of great blue herons located in "Ajax Warbler Swamp" (east side of Shoal Point Road, south of Bayly), grasshopper sparrow (listed as Special Concern under COSSARO), ermine, and grey treefrog. For a complete list of recorded fauna, please read the full technical report.

    Figure 3: A small colony of great blue herons (Ardea herodias) was recorded in the Carruthers Creek watershed.

    Figure 4: Rare within the region, a single grasshopper sparrow (Ammodramus savannarum) territory was located in the agricultural upper reaches of the watershed.


    Conclusion

    This report characterizes the vegetation and wildlife found within the Carruthers Creek watershed in the context of the quantity and quality of the available habitat patches. The amount of natural cover, along with the quality and distribution throughout the watershed, is not only important habitat for wildlife, but it also performs many ecosystem services for people. Natural cover improves air quality, reduces the risk of flooding and provides opportunities for pollination of food crops. The data collected will be used in later phases of the watershed plan to determine recommendations for management and protection of terrestrial wildlife.
