Hamm Creek is formed from a nearby spring called Comanche Springs that flows into it. The spring is close to the old Klondike boat docks that once heralded the Chisholm Trail cattle drives. It is said that even today there are signs of the chuck wagons that slowly traveled with the large cattle drives northward. The Klondike Mountains and Hamm’s Creek served as a barrier for controlling the herd’s direction to Cleburne and on to market.

Hamm Creek runs through The Retreat to Hamm Creek Park, a county park, which provides the only access to the Brazos River in Johnson County.
