text: Mexico The Cucapá are a group of indigenous people that live near the U.S.-Mexico border, mainly in Mexico but some in Arizona as well. For many generations, fishing on the Colorado River was the Cucapá's main means of subsistence. In 1944, the United States and Mexico signed a treaty that effectively awarded the United States rights to about 90% of the water in the Colorado River, leaving Mexico with the remaining 10%. Over the last few decades, the Colorado River has mostly dried up south of the border, presenting many challenges for people such as the Cucapá. Shaylih Meuhlmann, author of the ethnography Where the River Ends: Contested Indigeneity in the Mexican Colorado Delta, gives a first-hand account of the situation from Meuhlmann's point of view as well as many accounts from the Cucapá themselves. In addition to the Mexican portion of the Colorado River being left with a small fraction of the overall available water, the Cucapá are stripped of the right to fish on the river, the act being made illegal by the Mexican government in the interest of preserving the river's ecological health. The Cucapá are, thus, living without access to sufficient natural sources of freshwater as well as without their usual means of subsistence. The conclusion drawn in many such cases is that the negotiated water rights under the US-Mexican treaty that lead to the massive disparity in water allotments between the two countries boils down to environmental racism.
