3. AQUATIC SPECIES AT RISK

3.1 DETROIT RIVER

A federally and provincially listed Aquatic Species at Risk (SAR), Channel Darter (Threatened), has been identified in the Detroit River and has been captured in the approximate 300 m reach between Healy Drain and Broadway Drain. All mitigation measures outlined in Section 5 of this document must be adhered to at all times throughout proposed work in or near

Broadway Drain or any other drain/waterbody. The release of any deleterious substances including sediment and sediment laden water must be prevented. The deposition of fine sediments to a watercourse can be detrimental to aquatic organisms as a result of reducing streambed substrate composition. In addition to decreasing egg-to-fry survival rates in fish and impacting macroinvertebrate production, increased suspended sediment loads can clog the gills of fish and their ability to feed or migrate effectively.
