LAKE ERIE NORTH SHORE WATERSHED PLAN<br />

Seven of the eight field sites are within a designated municipal drain (three in Furry Drain, one in Chalmers<br />

Dickout Drain, and three in Little Marsh Drain). Bank instability and relatively deep unconsolidated sediment<br />

deposited along the channel bed was noted at a number of field sites. The possibility of rills/gullies present at<br />

almost all of the field sites indicates the potential for additional sediment entering the watercourse. Rill prevention<br />

measures such as slope re-grading, erosion control blankets, and seeding should be implemented along the<br />

adjacent property. Excessive sediment deposition can cause problems in the watercourse, such as lateral<br />

channel adjustments, increased turbidity, filling in of pools, and impacting fish habitat. Long term monitoring of<br />

sediment accumulation should be completed to avoid any potential problems and this can be done by the use of<br />

sediment traps. Six of the eight field sites are moderately entrenched, which means that flood waters will have<br />

little to no access to the floodplain. Confining the flood waters to the channel results in the loss of the adjacent<br />

floodplain, which impacts the hydraulic function of the watercourse (floodplains are storage areas for flood waters)<br />

and the physical habitat (loss of floodplain vegetation and the organisms that live there). It will also change the<br />

channel geometry overtime due to increased velocity, stream power, and channel slope. Increasing the variety<br />

and diversity of native plant species within small buffer zones will provide cover and habitat for fish, insects, and<br />

invertebrate along the watercourse. All recommendations should be discussed with the Drainage Superintendent.<br />

In addition to having an impact on aquatic and riparian habitat, drain maintenance has the potential to become<br />

quite costly through repeated maintenance activities. Naturalizing drains can potentially lengthen the time<br />

between maintenance events by reducing the amount of sediment entering and remaining in the drain. Best<br />

Management Practices for drain maintenance should be developed in consultation with, but not limited to, the<br />

following agencies; OMAFRA, DFO, MNR, Conservation Ontario, OFA, DSAO, CFFO, and the agricultural<br />

community to reduce ecological impacts to aquatic systems and to prevent sediment from returning to the drain.<br />

Any future maintenance of this watercourse should be done in accordance with Best Management Practices for<br />

drains. To review examples of current BMP mitigation measures, refer to Appendix I.<br />

Work with partnering stakeholders to promote shoreline areas that have been maintained naturally or restored to<br />

find a balance between natural processes and shoreline protection measures.<br />

Work with partnering agencies to mitigate water quality issues and work towards Blue Flag Beach status. Blue<br />

Flag status meets high standards with respect to water quality, environmental management, environmental<br />

education and safety and services (Blueflag.ca) and is known globally. Blue Flag beaches have the potential to<br />

increase tourism in the area.<br />

Opportunity potential is present for creating ecological linkages between natural areas creating larger contiguous<br />

natural features. Such areas have the potential to enhance movement of flora and fauna between natural areas<br />

as well as provide habitat and ecological diversity for a wide range of species.<br />

Many landowners keep their properties manicured or plant crops to the edge of the creek. The NPCA‟s program<br />

aimed at educating landowners about the benefits of buffer zones along watercourses should be extensively<br />

promoted. In addition, landowners should be made aware of and encouraged to participate in the NPCA‟s Water<br />

Quality Improvement Program. This program provides grants to a maximum of 75% of the cost of a project with<br />

caps between $2,000 and $10,000.<br />

Wetlands provide important water quality and ecological functions in a watershed by augmenting low flow, acting<br />

as natural filtration systems and helping to reduce flooding by acting like giant sponges and absorbing excess<br />
