The Pendills Creek/Sullivan Creek National Fish Hatchery Complex was established in 1951. Our mission is to rear lake trout as part of Great Lakes Restoration Program; to provide environmental education; to provide eggs for other hatcheries, research, and to administer the astroturf program - the astroturf program uses astroturf as a substrate for eggs, which are then placed in various locations in lakes Michigan and Huron. Over 38,000 visitors come every year, we provide fishery education and hatchery tours.
