About St. Marys State Fish Hatchery

This state fish hatchery along the east side of Grand Lake originated in 1913, and presently includes more than 160 acres. Of this total, 43 acres feature 26 fish-rearing ponds. The roads between the ponds include both gravel and paved asphalt surfaces, and are usually open for public use. Hatchery hours for the public are given as 8:00 a.m. to 4:30 p.m. weekdays, although many birders visit on weekends during daylight hours. Bird habitat includes narrow mowed grass strips between ponds, a few larger lawn areas, and the ponds themselves. Gulls, terns, geese, and wading birds are often found on the grassy areas. When ponds are drained in the spring or fall, mudflats can be extensive and attractive to shorebirds and wading birds, but during the summer, this usually results in very brief mudflat habitat before totally drying up. Both diving and puddle ducks can be found on the ponds, depending on peak migration periods. To the east of the fish-rearing ponds are open fields and two large “natural ponds” that are open for hunting during regulated seasons (beware). When hatchery personnel are stocking fish or maintaining ponds, please avoid driving in such areas. While there formerly were employees having an interest in birds, the last few decades have not been sympathetic to the great birding potential of the hatcheries, or to birders— again, be respectful of hatchery operations during business hours.
