All-American Canal

The All-American Canal is a concrete-lined waterway stretching over 80 miles through southeastern California that carries water from the Colorado River into the Imperial Valley. The channel delivers irrigation water to farmland across this dry region and was built as a major engineering project in the mid-1900s.

The waterway was constructed during the 1930s and completed in the early 1940s as part of a major irrigation initiative for the region. It opened the Imperial Valley to large-scale farming where the land was previously too dry to support significant agriculture.

The waterway shaped how people settled and farmed in this region, creating a shared resource that brought communities together around agriculture. You can see this influence in the way towns and villages developed along its path over the decades.

You can best explore the canal from the roads and pathways that run alongside it, which give you views of the waterway as it cuts through the landscape. The area is quite hot and dry during summer months, so visiting in cooler seasons makes for a more comfortable experience.

What makes this waterway memorable is its concrete lining, which was added to stop water from seeping away into the surrounding soil where it would be lost. Without this protective coating, a significant amount of water would drain away before reaching the farmland downstream.
