The first meeting was held January 19,2001, in <br />Albuquerque, The Engineer Advisers requested and received the participation of federal <br />agencies in part of that meeting for the principal purpose ofidentit'ying issues that were agreed <br />to be discussed in detail at the February Engineer Advisers meeting, The second meeting was <br />held February 27 through March 2 in Santa Fe, <br /> <br />. , <br /> <br />Sedimentation in Middle Rio Grande Reservoirs <br />Sediment surveys were conducted in 1998 for Abiquiu, Cochiti, and Jemez Canyon <br />Reservoirs, which are primarily flood control reservoirs Owned and operated by the U.S. Anny <br />Corps of Engineers (Corps), On the basis of the sediment surveys, the U.S. Bureau of <br />Reclamation (Reclamation) revised the sediment accumulation equations for use in daily <br />operations and accounting models. The area-capacity tables derived from the 1998 surveys <br />were made effective January I, 1999. Reclamation's 1999 Rio Grande water accounting <br />reflected the revised area-capacity tables but did not reflect the revised sediment accumulation <br />equations. Reclamation and the Engineer Advisers agreed the new sediment accumulation <br />equations were to be applied retroactively to January I, 1999, as part of Reclamation's 2000 <br />accounting work. Reclamation did not implement this direction until December 2000, at <br />which time it coordinated with the Corps for the release of excess, native Rio Grande storage, <br />some of which carried over into January 200 I. The total amount of water that was released <br />trom the three reservoirs was approximately 5,000 acre-feet. The amount of water that was <br />released In 2000 was approximately 1,000 acre-feet. An additional 4,000 acre-feet was <br />released In January and February ,of 2001. Fonnal accountingby Reclamation and the <br />Engineer Advisers of the retroactive application of the sediment accumulation equations must <br />now be deferred to the 200 I accounting. <br /> <br />~~',;,~:,?y ,'~.f~t:"" ,_",',~. <br />
