As seen in the pic, the Valley of Mexicali is a prolongation of the Imperial Valley and shares the waters of the Colorado River. For some reason the Imperial Valley appears much greener than the Mexicali Valley south of the border. However, the Arizona irrigated area is similar to its Mexican counterpart. The shining white areas may be salt. The City of Mexicali (a grey area on the border) has one million inhabitants and sends it wastewaters back to the Salton Sea in the USA through the New River. The Americans are lining all the canals which therefore will stop seeping water into underground currents towards the wells of the Mexicali Valley. The Americans are making efforts to start reducing irrigation water use, and they will not be happy watching how Mexicali wastes water. If they reduce drainage water infiltrating into the aquifer, which flows southwards, local wells will dry out. Devilishly complicated situation.
