Significant changes to an approved Plan of Operation necessitate amendment of the plan and
subsequent approval of the amended plan by the Arizona Water Banking Authority (AWBA) at a
public meeting. Two events occurred late in 2004 resulting in changes of significant magnitude to
warrant amendment of the existing Plan of Operation.
First, Central Arizona Project (CAP) staff informed AWBA staff that there would be a significant
decrease in capacity available to the AWBA at the Agua Fria Recharge Project and the Hieroglyphics
Mountain Recharge Project. As the AWBA had other partners within the Phoenix AMA/Maricopa
County that could utilize available water, the decision was made to transfer the water that could not
be stored at the AFRP and the HMRP to facilities that could utilize it. Consequently, 8,000 AF and
1,000 AF were transferred from the AFRP and HMRP facilities, respectively, to New Magma Irrigation
and Drainage District (2,500 AF) and the Granite Reef Underground Storage Project (6,500 AF). The
New Magma Irrigation District also received an additional 584 AF of AWBA water earlier in the year.
Additionally, by letter dated September 7, 2004, the Southern Nevada Water Authority (SNWA)
requested that the AWBA store 10,000 AF of SNWA’s unused Colorado River allocation within
Arizona. Following discussion with CAP staff and the Pinal County irrigation districts, it was
determined that the 10,000 AF could be delivered through the canal and could be utilized by the
Maricopa­Stanfied Irrigation and Drainage District (MSIDD) and the Central Arizona Irrigation and
Drainage District (CAIDD). Therefore, an additional 7,000 AF was scheduled for delivery to MSIDD
and 3,000 AF for delivery to CAIDD.
As these were the only changes made, it is my intent that this memorandum and the attached Table
2. Amended Water Delivery Schedule constitute the Amended 2004 Annual Plan of Operation.

Approved by AWBA on September 15, 2004
