LAKE ERIE NORTH SHORE

LAKE ERIE NORTH SHORE WATERSHED PLAN 7. Killaly Street East (WDMc-3(DS)): This section of watercourse is managed as a municipal drain; Michener Drain M-2. It has been channelized and there are a few bars present within the channel. Bank instability is present in the form of bare soil extending up the bank, as well as undercut banks. The vegetated buffer width is small in various locations along the watercourse. In-channel vegetation and algae were noted during a site visit in 2008. In some areas there is relatively deep unconsolidated sediment deposited along the channel bed. Small tributaries and/or possibly gullies/rills exist along the watercourse. Measurements taken at channel cross sections would indicate that the watercourse at this field site has moderate entrenchment which 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. Water quality should continue to 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. Projects to prevent and limit further development of rills adjacent to the watercourse should be implemented. Some examples include grassed waterways, chute spillways, tile drainage outlets, and proper tillage and cropping practices (OMAFRA, 1997a, and OMAFRA, 1997b). All recommendations should be discussed with the Drainage Superintendent. 8. Killaly Street East (WDMc-4(US)): This section of watercourse is managed as a municipal drain; Michener Drain M-2. It has been channelized and there are a few bars present within the channel. Bank instability is present in the form of bare soil extending up the bank. The vegetated buffer width is small along the residential property. In-channel vegetation and algae were noted during a site visit in 2008. Few to no pools were present along the streambed but there is stagnant water present throughout the study site. Measurements taken at channel cross sections would indicate that the watercourse at this field site has moderate to minor entrenchment which 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. Water quality should continue to be monitored in this watershed. All recommendations should be discussed with the Drainage Superintendent. 9. Weaver Road (WDMc-5): This section of watercourse is managed as a municipal drain; Michener Drain M-2. 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 form of bare soil extending up the bank. The vegetated buffer width is small adjacent to the fields. Few to no pools were present along the streambed but there is stagnant water present throughout the study site. Small tributaries and/or possibly gullies/rills exist along the watercourse. Increasing the size and diversity of native plant vegetation within the buffer zone will provide cover and habitat for fish, insects, and invertebrates along the watercourse. It will also provide a filter for sediment and chemicals that may enter the channel from runoff of fields and roads. Projects to prevent and limit further development of rills adjacent to the watercourse should be implemented. Some examples include grassed waterways, chute spillways, tile drainage outlets, and proper tillage and cropping practices (OMAFRA, 1997a, and OMAFRA, 1997b). All recommendations should be discussed with the Drainage Superintendent. 192

LAKE ERIE NORTH SHORE WATERSHED PLAN 10. Main Street East (WDMd): This section of watercourse is managed as a municipal drain; Michener Drain M-2. It has been channelized and lacks any depositional features along the stream bed which indicate little flow diversity within the channel. The vegetated buffer width is small in various locations along the watercourse which will impact habitat and cover over the stream. Few to no pools were present along the streambed but there are areas of stagnant water present. Measurements taken at channel cross sections would indicate that the watercourse at this field site is entrenched to moderately entrenched which results in flood waters having limited to no access to the floodplain. Therefore, the energy within the flow is contained in the channel. Increasing the size and diversity of native plant vegetation within the buffer zone will provide cover and habitat for fish, insects, and invertebrates along the watercourse. It will also provide a filter for sediment and chemicals that may enter the channel from runoff of fields and roads. All recommendations should be discussed with the Drainage Superintendent. 11. Miller Road (WDMd-2): This section of watercourse is managed as a municipal drain; Michener Drain M- 2. It has been channelized and lacks any depositional features along the stream bed which indicate little flow diversity within the channel. Bank vegetation made it difficult to identify instability but both banks were very steep. The vegetated buffer width is small in various locations along the watercourse which will impact habitat and cover over the stream. Few to no pools were present along the streambed but there is stagnant water throughout the field site. There is a watercourse that flows in between the agricultural fields which could be a gulley or a rill. Increasing the size and diversity of native plant vegetation within the buffer zone will provide cover and habitat for fish, insects, and invertebrates along the watercourse. It will also provide a filter for sediment and chemicals that may enter the channel from runoff of fields and roads. The watercourse that flows in between the vegetated fields should be monitored for bank instability to prevent additional sediment from entering the main watercourse. All recommendations should be discussed with the Drainage Superintendent. 12. Friendship Trail (WDTa): This section of watercourse is managed as a municipal drain; Wignell 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 form of undercutting, as well as bare soil exposed along an outer bend. The lack of large woody vegetation in the buffer zone impacts habitat and cover over the stream. Few to no pools were present along the streambed but there is stagnant water present throughout. The presence of algae was noted along the watercourse during a site visit in 2008. Tributaries and/or gullies/rills enter the watercourse at this field site. Measurements taken at channel cross sections would indicate that the watercourse at this field site has moderate to minor entrenchment which 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. Water quality should continue to be monitored in this 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. 13. Snider Road at Main Street East (WDTa-2): This section of watercourse is managed as a municipal 193
