Simomon River
The Simomon River is a narrow river which crosses and divides the town of Riverview in three. Long Island is located in the middle of the river, acting as the town center.
The land around the river seems extremely fertile, with a lot of farmlands and trees growing around. There are 5 bridges crossing the river to help transport in Riverview.
Because how the River is named and how there is countryside surrounding it, this river is probably based on the Sangomon River in Illinois.
