One of the most-viewed posts here on the photoblog is on the Imperial Dam and All-American Canal headworks, a post I put together while on a trip gathering photos and information for an upcoming series I have been producing on the Imperial Valley. The project is a self-produced project, one that is set aside when other (paying) projects and situations arise. As I am preparing now to pick up the project again, I have organized and sorted my pictures, and to whet your appetite for the project, as well as get my head back into it, here’s the Imperial Valley in pictures.

The Imperial Valley is one the world’s most productive agricultural regions and the nation’s largest year-round irrigated area. Here, the mild winter season and year-round water supply mean the area is always in production, with most fields being double or triple-cropped. During the winter, much of the nation’s lettuce, broccoli, cauliflower and other field crops are produced in the Imperial Valley, earning it the title of America’s winter salad bowl.
Several large growers, such as Earthbound Farms, own or lease land in the Imperial Valley, allowing them to produce commodities under their labels year-round. This newly planted field of salad greens …
One of the first major crops to come out of the Imperial Valley was cantaloupe; a deal between Southern Pacific Railroad and Imperial Valley growers in the early 1900s had cantaloupe trains delivering the tasty melons to the eastern markets long before their local growers were producing; the cantaloupe trains launched the Pacific Fruit Express, setting the standard for delivering fresh produce to different areas of the country. Cantaloupe still remains a big crop for the Imperial Valley. This photo sequence shows the planting of cantaloupe in January for harvesting in the spring. First the seeds are planted …
But plenty of it will go to California dairies and to feed the 300,000 or so cattle at Imperial Valley feed lots, too.
Hydroelectric plants are located all along the route to take advantage of any elevation drops for electrical power production.
The Imperial Irrigation District manages over 1500 miles of canals and laterals which deliver water to approximately 5600 gates serving the 479,000 acres of farmland within the Imperial Valley. The entire system is above ground and much of it is still operated manually.
The recently completed Drop 2 Reservoir (renamed the Warren Brock reservoir) is an 8,000 square-foot reservoir built to capture water that would otherwise flow on to Mexico, and conserve it for use within the Imperial Valley. Here, at a spot called “Drop 1″ along the All-American Canal, water destined for the Coachella Valley departs on the right, while water headed towards the Drop 2 Reservoir would flow through the canal to the left.
Due to the high salt content of the soil, coupled with the high salt content of the Colorado River’s water, the fields must be periodically leached to keep accumulated salts below the root zone. A system of tile drains underneath the fields pulls the drainage water from beneath the field.
… and the New River. (This is the New River, closer to the Salton Sea. By now it has traveled some 200 miles since crossing the border, and the water has been cleaned up considerably. This is the New River as it crosses the border at Calexico.)
The flow of New and Alamo Rivers which feed the Salton Sea is largely comprised of agricultural drainage water and is the main source of inflow for the Salton Sea. Here, the New River meets the Salton Sea.
And so here is where our water story ends, at least for now, here at the Salton Sea. The water has traveled from Imperial Dam, through the rich fields of the Imperial Valley, and this is what is left over. If you consider that the waters of the Colorado River are used and resued as the farms and cities along the river’s route draw their water and return their drainage water and treated wastewater to the river, then really the Salton Sea represents the left-overs and discards of the entire civilization that exists along the Colorado River’s route. And since the Colorado River rarely reaches the sea anymore, it is the real end of the line.
The Salton Sea has its own story to tell, one of boom, bust, and dead fish.
One of the last bits of remaining habitat for birds and migrating waterfowl in the lower Colorado River area, it nonetheless faces an uncertain future. It’s a story I plan to tell you as I work on my Imperial Valley project.
