The purpose of the Water Assurance and Treaty Enforcement for Rio Grande Farmers Act, also known as the WATER for Farmers Act, is to ensure that the United States receives a reliable supply of water from Mexico as outlined in the 1944 Water Treaty. The Act aims to address the economic losses faced by American agricultural producers in South Texas due to water delivery shortfalls from Mexico. Key provisions of the Act include the establishment of a process to determine if Mexico has met its water delivery obligations under the treaty.
