Built in 1906, this dam raised the Rock River water level by 11 feet so it would flow into the Hennepin Canal. It was restored in 2008 with an added pedestrian walkway. Cross over from Rock Falls into Sterling, enjoy a leisurely stroll and check out the Dillon Home museum and Sterling-Rock Falls Historical Society on the other side!  In Rock Falls, you can enjoy the Jim Arduini Boat Launch, the Hennepin Canal or a walk along the River's edge!
