오타이 저수지 댐

The Otay Reservoir Dam, officially known as Savage Dam, has a dramatic past. The original Lower Otay Dam, a rock-fill structure, was completed in 1897. However, in January 1916, after heavy rains, it catastrophically burst, causing widespread flooding and at least 14 deaths. The current concrete arch-gravity dam was rebuilt in 1918 and named Savage Dam in honor of city engineer Hiram Newton Savage.
