LAKE ERIE NORTH SHORE

LAKE ERIE NORTH SHORE WATERSHED PLAN and cover. There is an area where vegetative debris is being thrown onto the bank. This debris will eventually end up in stream which can cause debris jams and impact water quality. Dense instream vegetation and algae were noted during a site visit in 2008. A grate covering the culvert at Vimy Road may restrict larger fish from entering the watercourse. Water quality should be monitored in this watershed. Due to the impact on water quality it is advised that landowners stop throwing vegetated debris over the bank. An assessment should be completed on whether or not the concrete block wall or the riprap could be replaced with a soil bio-engineering structure. This would increase habitat and cover along the channel and still provide bank stabilization. All recommendations should be discussed with the Drainage Superintendent. 1. 2. Vimy Road (OMCMb): This section of watercourse is managed as a municipal drain; Oil Mill Creek Drain. It has been channelized and lacks any depositional features along the stream bed which indicate little flow diversity within the channel. Bank instability is present in the wooded area as bare soil extending up the bank which may be due to the dense canopy cover over the channel. Small debris jams exist within the wooded area and there is some trees right at the edge of the channel indicating bank instability. In the open area of this park the buffer zone consists of a few trees and a manicured lawn that is mowed to the edge of the watercourse. Fairly large amounts of duckweed and algae were noted along this channel during a site visit in 2008. In the upstream sections of the study site there are areas where relatively deep unconsolidated sediment is deposited along the channel bed. Few to no pools exist along the bed but there is stagnant water present throughout the field site. Measurements taken at channel cross sections would indicate that the watercourse has varying degrees of entrenchment, from minor to complete entrenchment. This results in flood waters having limited to no access to the floodplain. Therefore, the energy within the flow is contained in the channel. Recommendations for this site include not grading the channel banks too steep during the dredging process so that deep rooted vegetation can become established along the banks and stabilize the soil. Creating a buffer in the open area of the park with a variety of native plant species will help to create cover and habitat for fish, insects, and invertebrates. Water quality should be monitored in this watershed. Monitoring the accumulation of sediment along the channel bed can be done by the use of sediment traps throughout the watercourse. Alternatives to traditional drainage design, such as wetland creation, floodplain development, and increasing channel curvature should also be considered. All recommendations should be discussed with the Drainage Superintendent. These two field sites are within the designated municipal drain Oil Mill Creek Drain. Both of the sites had areas of bank instability but only the upstream site had relatively deep unconsolidated sediment deposited along the channel bed. There are a number of small tributaries entering the main channel, as well as bare soil exposed along the banks. These two factors may be contributing to the sediment along the channel bed. Excessive sediment deposition can cause problems in the watercourse, such as lateral channel adjustments, increased turbidity, filling in of pools, and impacting fish habitat. Long term monitoring of sediment accumulation should be completed to avoid any potential problems and this can be done by the use of sediment traps. Increasing the variety and diversity of native plant species within small buffer zones increases canopy cover, habitat, and also provides a filter mechanism for sediment and chemicals from runoff of fields and roads. Water quality should be monitored in this watershed. All recommendations should be discussed with the Drainage Superintendent. Naturalizing Drains and Drain Best Management In addition to having an impact on aquatic and riparian habitat, drain maintenance has the potential to become quite costly through repeated maintenance activities. Naturalizing drains can potentially lengthen the time between 208

LAKE ERIE NORTH SHORE WATERSHED PLAN Practices Promote Good Shoreline Stewardship Blue Flag Beaches Integrated Roadside Vegetation Management (IRVM) Program Ecological Linkages between Natural Areas Riparian Buffer Education Program Wetlands are Worth It Program Agricultural Best Management Practices Program Abandoned Well Decommissioning Program maintenance events by reducing the amount of sediment entering and remaining in the drain. Best Management Practices for drain maintenance should be developed in consultation with, but not limited to, the following agencies; OMAFRA, DFO, MNR, Conservation Ontario, OFA, DSAO, CFFO, and the agricultural community to reduce ecological impacts to aquatic systems and to prevent sediment from returning to the drain. Any future maintenance of this watercourse should be done in accordance with Best Management Practices for drains. To review examples of current BMP mitigation measures, refer to Appendix I. Work with partnering stakeholders to promote shoreline that have been maintained naturally or restored to find a balance between natural processes and shoreline protection measures. Work with partnering agencies to mitigate water quality issues and work towards Blue Flag Beach status. Blue Flag status meets high standards with respect to water quality, environmental management, environmental education and safety and services (Blueflag.ca) and is known globally. Blue Flag beaches have the potential to increase tourism in the area. Niagara Region and municipalities should work together to expand Niagara Region‟s IRVM Program. IRVM integrates the use of native vegetation with appropriate management techniques to produce a cost-effective, environmentally sound management alternative for roadside weed and erosion control while providing numerous ecological benefits (e.g. buffer strips). Focus of program expansion should be directed to main roads and roads in areas with a high shallow intrinsic susceptibility. Opportunity potential is present for creating ecological linkages between natural areas creating larger contiguous natural features. Such areas have the potential to enhance movement of flora and fauna between natural areas as well as provide habitat and ecological diversity for a wide range of species. Many landowners keep their properties manicured or plant crops to the edge of the creek. The NPCA‟s program aimed at educating landowners about the benefits of buffer zones along watercourses should be extensively promoted. In addition, landowners should be made aware of and encouraged to participate in the Conservation Authority‟s Water Quality Improvement Program. This program provides grants to a maximum of 75% of the cost of a project with caps between $2,000 and $10,000. Wetlands provide important water quality and ecological functions in a watershed by augmenting low flow, acting as natural filtration systems and helping to reduce flooding by acting like giant sponges and absorbing excess water. The Wetlands are Worth It Program through NPCA‟s Water Quality Improvement Program aims to assist landowners that are interested in restoring, protecting, rehabilitating and creating wetland habitat on their property by providing grants to a maximum of 75% of the cost of a project with a grant ceiling of $10,000. The NPCA‟s program aimed at educating landowners about the benefits of rural and agricultural best management practices should be extensively promoted. In addition, landowners should be made aware of and encouraged to participate in the Conservation Authority‟s Water Quality Improvement Program. This program provides grants to a maximum 75% of the cost of a project with caps between $5,000 and $12,000 depending on the project. Abandoned wells that are not properly decommissioned (capped and sealed) pose a threat to groundwater resources by providing a direct route to groundwater. The NPCA has a well decommissioning program in place for its jurisdiction. Grants are available for the decommissioning of unused water wells only. Priority is given to hydrogeologically sensitive areas, projects located in areas with a high density of domestic water wells, and areas where watershed plans have been completed or are ongoing (NPCA 2007). Approved grants will cover 90% of well decommissioning costs to a maximum of $2,000 per well (limit of 2 wells per property). This is a reimbursement program, which means that the landowner will pay the full cost to the contractor, and will be reimbursed for 90% of the total project cost after all receipts, invoices, and water well decommissioning records are submitted to the 209
