The freshwater springs here feed a state fish hatchery that covers 400 acres of parkland. According to residents, the waters that flow from the springs form the shortest river in the world, the 200-foot-long Roe River (Oregonians hold that their D River is shorter, but most independent record keepers side with Montana on the issue). In addition to the hatchery, a visitor center, picnic grounds, a river drive, hiking and biking trails, and a playground are all on-site, and you can walk up the hill to Fish, Wildlife & Parks' regional headquarters, filled with educational displays featuring life-size mounts of area wildlife. You can also fish, attend educational programs, and take tours. Kids will enjoy feeding the hatchery's fish.
