The ideal streamflow range for the river run is between 400-1000 cfs. The river has multiple rapids and obstacles, including the S-turn rapid, which is a tight and technical rapid that requires precise maneuvering. Other notable rapids include the Rock Garden and the Slot, which require paddlers to navigate around rocks and tight channels.
In terms of regulations, all boaters are required to wear a personal flotation device, and it is recommended to have a helmet as well. Additionally, there are no private property concerns along the river, but it is important to respect the natural environment and leave no trace. The river is open year-round, but it is important to check water levels and weather conditions before embarking on a trip.
It is important to note that while Mill Creek is a popular whitewater destination, it can also be dangerous for inexperienced paddlers. It is recommended to have prior whitewater experience and to paddle with a group or experienced guide.
