Info

The Barrie Creeks, Lovers Creek and Hewitt’s Creek Subwatershed Plan Hewitt’s, and Innisfil Creeks. These targets should be based on the Guidance Document framework (LSRCA 2010) which is being used for the Maskinonge River subwatershed. Recommendation 5-10 – That the MOE, with assistance from LSRCA and MNR, develop a strategy to achieve the instream flow regime targets. This strategy should address both high and low flow requirements and provide a plan for implementing strategy recommendations. Recommendation 5-11 – That the LSRCA work with subwatershed municipalities and MAFRA to examine the suitability of using the Drainage Act to protect and restore the ecological function of watercourses 5.6.4 Water Quality and Water Temperature Based on the generally fair to fairly poor benthic invertebrate community scores, water quality in Barrie Creeks, Lovers Creek and Hewitt’s Creek can be considered degraded in some areas. Similarly, the assessment of fish IBI and water temperature indicate that the thermal regime of the creeks is being affected by factors such as loss of riparian cover, increased imperious surfaces and barriers. Recommendations addressing water quality are presented in Chapter 3 – Water Quality, and recommendations pertaining to increased water temperature are described in Recommendations 3-18 and 3-19. 5.6.5 Enclosures Past development practices allowed for the enclosure or piping of various creeks throughout the study area. These enclosures not only create barriers for fish migration and fragment the fish and wildlife populations but also threaten the public through the potential for flooding. In the case of both Kidd’s and Sophia Creeks, the enclosure of a significant part of the mouth of creek has unfortunately curtailed fish migration from Lake Simcoe to the headwaters completely and in the case of the latter, has lead to a complete absence of fish within the system. Recommendation 5-12 - That the City of Barrie, in partnership with the LSRCA, complete an inventory of enclosed or buried streams from which removal of enclosures or “day lighting” can be prioritized. Recommendation 5-13 - That the City of Barrie continue its efforts to day light enclosed streams and establish a funded program based on prioritized list of restoration opportunities, as resources permit. 5.6.6 Monitoring and Assessment Long term monitoring is required to identify changes and trends occurring in the aquatic community. These on-going annual surveys of fish, invertebrates, stream temperatures, water quality, baseflow and channel morphology are also intended to provide information that will direct future rehabilitation efforts. Additional environmental characteristics such as brook trout spawning (redd) surveys, field confirmation of groundwater inputs, algae/diatom sampling, lake /tributary interface assessment, as well as an expanded water quality and quantity network will need to be considered to provide the information to look at the system in an integrated and holistic way. A renewed need for regular reporting of the results and a systematic re-evaluation of the program is also required. Chapter 5: Aquatic Natural Heritage 259
The Barrie Creeks, Lovers Creek and Hewitt’s Creek Subwatershed Plan Recommendation 5-14 – That LSRCA, with support from Municipalities and the Province, aim for improved spatial and temporal resolution in annual monitoring of aquatic habitat, including water quality, fish and benthic indicators. Recommendation 5-15 – That the LSRCA, with support from subwatershed municipalities and the Province, investigate the reasons for the significant shift in biotic community and thermal regime seemingly associated with Hwy 400. This investigation should make recommendations as to how any identified impacts may be mitigated. Chapter 5: Aquatic Natural Heritage 260
