As part of the Castalia Blue Hole system of underground springs, the area provides a unique birding experience. With the available supply of fish, herons, and egrets are common.

Castalia State Fish Hatchery is located on 90 acres in western Erie County, just southwest of Sandusky, Ohio. This facility is the newest of the six hatcheries and came on-line in the fall of 1997 after it was purchased from private interests. The hatchery production facilities consist of eight indoor rearing troughs and three outdoor raceways. Nine of these raceways are supplied with water from one of the area’s many blue-hole aquifers (2,500 gallons per minute capacity). Because the water from the blue hole has no oxygen and high levels of nitrogen, it is treated before being used by the hatchery. The remaining two raceways are supplied with water diverted from Cold Creek (10,000 gallons per minute capacity). This cold water supply allows the hatchery to raise steelhead and rainbow trout. All of the state’s steelhead production occurs at this hatchery. Rainbow trout are raised to catchable size before being stocked in Ohio lakes in both the spring and fall.

The facility offers great wildlife viewing opportunities.

To get to the hatchery, take OH-269 south off of US-6 and then go 2 miles. Turn left on Heywood Road; after one mile, turn right on Homegardner Road and the hatchery is 200 feet on the right.
