The International Boundary and Water Commission (Spanish: Comisión Internacional de Límites y Aguas) is an international body created in 1889 by the United States and Mexico to administer the many boundary and water-rights treaties and agreements between the two nations. The organization was created as the International Boundary Commission by the Convention of 1889, and given its present name under the 1944 Treaty. Under these agreements, the IBWC has a U.S. section and a Mexican section, headquartered in the adjoining cities of El Paso, Texas, and Ciudad Juárez, Chihuahua. The U.S. section is administered by the United States Department of State; the Mexican part by the Secretariat of Foreign Relations of Mexico.
