This fish hatchery produces approximately 1.5 million lake trout annually to be stocked in Lake Michigan and Lake Huron. In addition, about 65,000 brook trout are stocked in Lake Superior waters where stocks are depleted. Approximately ten thousand lake trout and coaster brook trout brood fish are held in the broodstock facility to provide 4 million and 700,000 eggs respectively for conservation of these species.
