When water first came to the Imperial Valley through canals from the Colorado River, the event was marked simply.
"It's arrival in Imperial was not the occasion of any special celebration …" Otis B. Tout writes in his 1931 book "The First Thirty Years."
"… only half a dozen or so were on hand to toss their hats into the air," Tout writes.
Now, 100 years later to the day, a much bigger celebration is planned.
The Imperial Irrigation District and the Comisión para la Preservación Cultural de Mexicali y su Valle will stage a binational centennial celebration of bringing water into the two valleys Wednesday.
The event will begin at 4:30 at Sharp's Heading, one mile south of the new port of entry in Mexicali. There will be music, dancers, a photographic exhibit and commemorative inauguration.
