As the United States Commissioner, I am pleased to welcome you to the web site of the United States Section, International Boundary and Water Commission (USIBWC). On behalf of all USIBWC employees, I invite you to explore our web site.  We hope you, as an important stakeholder, discover how and why the USIBWC carries out its critical mission as America's premiere federal agency responsible for addressing technical transboundary management issues in the United States - Mexico border region. We continually strive to carry out our mission through binational cooperation and in a manner that is responsive to the needs of all stakeholders.

Established in 1889, the International Boundary and Water Commission (IBWC) has responsibility for applying the boundary and water treaties between the United States and Mexico and settling differences that may arise out of these treaties. The IBWC is an international body composed of the United States Section and the Mexican Section, each headed by an Engineer-Commissioner appointed by his/her respective president. The United States Section of the International Boundary and Water Commission (USIBWC) is headquartered in El Paso, Texas. To learn more or click here.
