Mating reef set for Detroit River island
Officials hope to complete preconstruction research this fall and begin building the reef to enhance the sole International Wildlife Refuge in North America next year, Hartig said.
The reef will span about 70 yards along the shoreline in the northeast corner of Fighting Island.
Hartig estimates the second phase, or construction of the spawning reef, will cost between $150,000 and $200,000, and the third phase, post-construction assessment will be about $50,000.
