While there was some improvement to streamflow due to above average precipitation in 2004 in
parts of the basin in Colorado and New Mexico, streamflows in general continued to be substantially below

the entire year. Consequently, Article VII of the Compact was in effect during the entire year.
The Engineers Advisers met in Santa Fe and Albuquerque from February 28 through March 4 to
prepare the 2004 Compact water accounting and to discuss continuing and new issues in preparation for
the 2005 annual meeting of the Rio Grande Compact Commission (Commission). The Engineer Advisers
