Actual Put-in

Underwood Creek at the Actual Put-in near Brookfield is a medium-sized stream in Waukesha County with significant gradient and flow characteristics suitable for whitewater paddling. The creek features an average gradient of 150.6 feet per mile, which is substantial and indicates regular rapids and moving water. With an average flow of 4.20 cubic feet per second and velocity of 0.99 feet per second, this is an active waterway that requires paddling skill and attention to current conditions.

As a headwater stream located near the source of the creek system, water levels and conditions can be variable depending on recent rainfall and seasonal factors. Paddlers should be prepared for the 150.6 foot per mile gradient which translates to consistent dropping terrain throughout the run. The creek is relatively short at 11.09 miles total length, with the put-in located about 10 miles from the river mouth, meaning you are in the upper reaches of the system.

Paddlers using this access should have intermediate to advanced whitewater skills given the gradient and current velocity. Water conditions will typically be faster-moving with potential obstacles common to headwater streams. Always check current water conditions and flows before paddling, and be aware that small headwater streams can rise quickly after heavy rain or snowmelt.
