8.0 Grants Creek Catchment: Actions/Opportunities
Actions noted by the Friends of the Tay Watershed Association (FoTW) are indicated by an asterisk.
Aquatic Habitat/Fisheries
Educate waterfront property owners about fish habitat requirements, spawning timing and near-shore and in-water activities that can disturb or destroy fish habitat and spawning sites.
Work with various partners, including landowners, the Friends of the Tay Watershed Association and Tay Valley Township on fish habitat enhancement projects in the Tay River watershed, building off of new knowledge and the recommendations as described in the report "Fish Habitat of the Tay River Watershed: Existing Conditions and Opportunities for Enhancement" (2002) prepared by MNR, RVCA, Parks Canada, and DFO.
Investigate public complaints about the low summer flow on Grants Creek to seek a better understanding of its impact on in-water fish and wildlife, said to be caused by inadequate release(s) from the Pike Lake Dam during low water conditions.*
Development
Work with approval authorities (Lanark County, Leeds Grenville and Lanark District Health Unit, Mississippi Rideau Septic System Office, RVCA and Tay Valley Township) and landowners to consistently implement current land use planning and development policies for water quality and shoreline protection adjacent to Grants Creek and headwater streams in the catchment (i.e., a minimum 30 metre development setback from water).
Explore ways and means to more effectively implement and enforce conditions of land-use planning and development approval to achieve net environmental gains (particularly with respect to rehabilitating or protecting naturally vegetated shorelines and water quality).
Encourage Committees of Adjustment to take advantage of technical and environmental information and recommendations forthcoming from planning and environmental professionals.
Ongoing education and dialogue regarding the regulatory floodplain, its implementation and the effect it has on development continues to represent an opportunity to assist the public in understanding the importance of planning, which respects this natural hazard.
Municipalities in the Tay Watershed are encouraged to strengthen natural heritage and water resources official plan policies and zoning provisions (pertaining to water setbacks, frontage and naturalized shorelines and wetland protection) where deemed appropriate.
Work with Lanark County, Tay Valley Township and agencies to ensure that development approvals around lakes and along watercourses take into consideration the protection of fish habitat (including the near-shore nursery and spawning habitat).
Utilise RVCA subwatershed and catchment reports to help develop, revise and implement official plan policies to protect surface water resources and the natural environment (including woodlands, wetlands and shoreline cover).
Land Cover
Consider reforestation of the Grants Creek catchment to raise the current level of forest cover (at 28 percent) above the recommended 30 percent minimum threshold that is needed to sustain woodland dependent species and woodland biodiversity on the landscape. Reaching this target will also help to improve the capacity of the forests in the catchment to reduce flooding and water-borne soil erosion, store more carbon and dampen the effects of the changing climate. Take advantage of the RVCA Trees for Tomorrow Program to achieve this on idle and/or marginal land.
Establish RVCA regulation limits around the 34 percent (162 ha.) of wetlands in the catchment that are unevaluated. Doing this will help protect landowners from natural hazards including mitigating surface water flow by storing water during periods of peak flow (such as spring snowmelt and heavy rainfall events) and releasing water during periods of low flow (this mitigation of water flow reduces flood damage), as well as contributing to the stabilisation of shorelines and to the reduction of soil erosion damage through water flow mitigation and plant soil binding/retention.
Shorelines
Take advantage of the RVCA Shoreline Naturalization Program to re-naturalize altered creek and stream shoreline identified in this report as “Unnatural Riparian Land Cover". Target shoreline restoration at sites shown in orange on the Riparian Land Cover map (see Figure 66 in Section 4.4 of this report) and on the Riparian Restoration Opportunities map (see Figure 54 in Section 3.3.14 of this report). Concentrate stewardship efforts along the headwater and tributary streams of Grants Creek in the catchment, which have 54 percent of the total length of their shoreline composed of natural vegetation (this is below the recommended 30 metre wide, naturally vegetated shoreline buffer target to be aimed for along 75 percent of the length of the catchment’s watercourses). Other stewardship opportunities in the catchment may be determined based on septic system inspections and surface water quality monitoring results.
Promote the use of bioengineering methods (using native shrub/tree planting, fascines, live stakes) as a shoreline erosion mitigation measure as well as a cost effective alternative to shoreline hardening (with rip rap, armour stone, gabion baskets, walls).
Educate landowners about the value and importance of natural shorelines and property best management practices with respect to shoreline use and development, septic system installation and maintenance and shoreline vegetation retention and enhancement (Leeds Grenville and Lanark District Health Unit, Mississippi Rideau Septic System Office, RVCA and Tay Valley Township).
Water Levels
Install stream flow and water level instrumentation along Grants Creek.
Water Quality
Consider further investigation of the Poor to Fair surface chemistry water quality rating and Poor to Fair instream biological water quality rating on Grants Creek as part of a review of RVCA's Baseline and Benthic Invertebrate surface water quality monitoring. As part of the investigation of the Poor to Fair results, consider a more extensive review of surface water quality along the reach of Grants Creek in the vicinity of the Upper Scotch Line (at the Bowes Side Road), adjacent to the auto-wrecking salvage yard.
Offer funding provided by the RVCA Rural Clean Water Program to landowners with potential projects that could improve water quality on Grants Creek and its tributaries (e.g., livestock fencing, septic system repair/replacement and streambank erosion control/stabilisation). Concentrate efforts at septic systems requiring remedial work or replacement, including the 15 identified as needing additional maintenance/remedial/replacement work since 2004. Target funding towards those properties where livestock access to Grants Creek continues and remains an ongoing concern to the public and agencies.*
Educate waterfront property owners about septic system care by providing information about sewage system maintenance (i.e., when to pump out septic systems and holding talks) through initiatives such as the Septic Savvy Workshop and services provided by the Mississippi Rideau Septic System Office.
Reduce pollutant loading to Grants Creek through education about the application of shoreline, stormwater and agricultural best management practices; also consider using low impact development (LID) methods to improve the quality and reduce the amount of stormwater runoff directly reaching the river ecosystem. This will be particularly beneficial in areas with extensive impervious surfaces (i.e., asphalt, concrete, buildings, and severely compacted soils) or on sensitive shoreline properties (with steep slopes/banks, shallow/impermeable soils).
