The "river" itself has moved through the area for eons. However, like many Texas rivers, it meandered most of the time through the Trinity Basin. During the rainy seasons, water collecting from all points north widened river until it washed out the basin from up along Maple Ave. and the rock hill where the Beer Water Falls sits today [ the old Baby Doe's Ridge ] across to Colorado Blvd. on the east.
