The fish hatchery is right next to the state park, located here because it uses water from the spring. There’s a fancy visitor center with a pool in front of it.
The pool is filled with carp and Alligator Gars, which really do look like alligators from some angles.
The inside was impressive also, with two large tanks and several smaller ones containing fish, turtles, and eel (it was inside a log and I couldn’t get a photo). The walls were lined with displays on the spring, the hatchery, the fish, etc.
I’d read on line that you could walk around the ponds and see the trout, but when I asked the guy in the gift shop what there was outside for visitors to see, he said nothing really, because of the flood. Apparently there was a huge flood in May, 2025 that covered the whole area, ruining equipment in the buildings and, presumably, letting the fish out into the river. They’re waiting for government funding to get things fixed again. Here’s an overview photo of the hatchery and park.
It took me about 20 minutes to see what there was to see, although it was definitely worth the visit since I was in the area.
