The Upper Mexican Heading (also known as intake Number 3), located just south of the US / Mexican border, was the second of three channels that were dug to maintain sufficient water flow in the Imperial / Alamo Canal for the crops growing in the Imperial Valley. It was dug because the Chaffey Headgate had been constructed improperly and was built to high to allow water to flow into the canal when the Colorado River was low.
