It is a small facility located behind a community college. It was a little hard to find, but there it was next to the park. You can have a picnic at the park after you visit the fish.
The place is open air and there is no fee. You may buy fish food for .25 cents if you want to feed the fish. The kids watched, learned about fish and what is a fish hatchery. This was their first time visiting a fish hatchery. So I asked what they thought of the place. One of them said this:
"The humans found eggs that were in danger and decided to bring them here to protect them. The humans will later take them back to the lake or stream once they grow big. They will see their mommies soon. The trout are here just for a few moments, so they stay protected." It was very interesting to hear their point of view.
