Ennis National Fish Hatchery

The Ennis National Fish Hatchery (NFH) began operations in July, 1933.  As a broodstock hatchery, the purpose of the Ennis hatchery is to grow fish to adult size and harvest the eggs which are then sent to hatcheries in 23 states.  Here, the broodstock produced is rainbow trout and over 20 million rainbow trout eggs are harvested annually.  Ennis NFH is the largest broodstock hatchery in the Forest Service National Broodstock Program and one of only two rainbow trout hatcheries in the federal system.

The location of the hatchery is ideal.  Water to supply the hatchery comes from Blain Springs – a pure, disease-free, clean water source that flows at 15,000 gallons per minute.  The water is a constant 54 degrees which is ideal for nurturing trout.  Once the water has passed through the hatchery, it is used for irrigation by several downstream ranches.

Fish from the hatchery are not released into the Madison River as it has been a wild, unstocked river since the 1970’s.  Adult fish from the hatchery are used to stock the pond at Lion’s Club Park in Ennis in time for the Father’s Day Fishing Derby.

You can stop by and visit the hatchery from 9-3 for a tour of the facility.  Call ahead for a group visit, or just drop by.
