Put In is a purpose-built play feature within the Elkader Whitewater Park, offering local paddlers a consistent surfing and training wave. The feature provides a controlled environment for practicing whitewater techniques, with a relatively uniform hydraulic that allows for multiple boat types to practice eddy turns, surfing, and other river skills. While designed for skill development, paddlers should still approach with standard whitewater safety practices and be aware of potential shallow areas or submerged structures.
