2.3 DETROIT RIVER

The Detroit River is a large riverine system that connects Lake St. Clair to the western basin of Lake Erie. As a whole, this system supports a diverse fish community including some aquatic Provincial and Federal SAR (see Section 3.1). The nearshore area located adjacent to the Broadway Drain outlet supports a nearshore fish community comprised of both cool and warm water fish species. Substrates in this near shore area consist of sand, gravel, cobble and clay. Water levels in the Detroit River are known to fluctuate in response to changing water levels within the Great Lakes. For estimated water depths within the proposed work area, see design drawings located in Appendix A. For records of fish species collected in the Detroit River in the immediate vicinity of the Early Works site, refer to Table 1.
