Below - Photo of a photo: On June 14, 1951, 50 Princesses and the Queen of the Washington State Apple Blossom Festival participated in a symbolic pouring ceremony. Standing at the top of the canal wall, they emptied gallon jugs of water from all 48 states, plus the territories of Alaska and Hawaii, and the District of Columbia into the newly completed feeder canal. The ceremony symbolized the entire country's contribution to the project, and the benefit the project would have to the country's economy when irrigation started the following spring. |
