Lucky Peak Dam and Lake managers will implement a $5 boat-launch fee on May 15 to help reduce seasonal traffic congestion which routinely occurs at the U.S. Army Corps of Engineers-managed Macks Creek Park. The park, located on Arrowrock Road, about 4 miles from the Highway 21 intersection, is a small family-friendly recreation area offering a wide range of options for water recreation, dry camping and day-use activities, and is the only vehicle-accessible camping area at Lucky Peak Lake.
