You can cycle across the top of the dam, which was constructed in 1928 to help control flooding in the region. It stands at 147 feet high, and today supports a myriad of outdoor recreation activities on the reservoir.

Great view of the Puddingstone Reservoir, a 250-acre man-made body of water. There is a road that runs along the perimeter of the reservoir and there is a spot to pull off the road to get a close up view of the water.
