St. Marys River in Indiana
The St. Marys River is a tributary of the Maumee River. It is approximately 100 mi (160 km) long, and runs through northwestern Ohio and northeastern Indiana. It drains a primarily rural farming region in the watershed of Lake Erie.
The St. Marys River is formed in southern Auglaize County in western Ohio by the confluence of the short East Branch and Center Branch. It flows primarily WNW through northwestern Ohio into Adams County, Indiana, where it flows northwest past Decatur, then enters Fort Wayne. It hooks around in its last half mile (0.8 km) to join the St. Joseph River from the west, where they then form the Maumee River in downtown Fort Wayne.
Doctor and hospital care is available in Fort Wayne.
