EL PASO, Texas -

(AP) - Mexico has agreed to more water into the Rio Grande for use by agriculture and other interests on the Texas side of the river.
    
In a letter to South Texas congressman, The International Boundary and Water Commission says the Mexican government acceded during the past week to commission requests for more water from Rio Grande tributaries in Mexico.
    
However, U.S. Commissioner Edward Drusina says Mexico has been "slower than expected" in responding to U.S. water requests and "more is needed to address the existing water deficit and the immediate water needs of South Texas."
    
In a letter dated Friday, Drusina said he and his staff continue to push for quicker, fuller action by Mexico. However, he said plans for new dams in Mexico's Rio Conchos basin raise new concerns.
