SUMMARY:  Staff has prepared a draft Water Production Summary Report for Water Distribution Systems (WDSs) within the District for Water Year 2004 (WY 2004).  WY 2004 covers the 12-month period from October 1, 2003 through September 30, 2004.  Preliminary computations indicate that 16,658 acre-feet (AF) of water were produced by the 50 recognized WDSs in the District during WY 2004.  The California American Water (Cal-Am) main system, which is the largest WDS in the District, accounted for 15,185 AF or 91% of the total production reported by WDSs in WY 2004.

 

RECOMMENDATION:  This report is for informational purposes only.  The Board should review the draft summary report and provide staff with any comments or questions.  Staff will complete and file the final report, incorporating any late revisions, if this item is approved with the Consent Calendar.

 

BACKGROUND:  All owners and operators of WDSs within the District are required to annually submit water production information to the District.  WDSs are defined as works within the District used for the collection, storage, transmission, or distribution of water from the source of supply to the connection of a system providing water service to any connection including all water-gathering facilities and water-measuring devices.  Two new single-connection systems (i.e., Tobey and Pelio) were established during WY 2004. 

 

Each WDS must report the amount of water produced and delivered, in addition to the number of existing and new connections served during the reporting period. The information for WY 2004 is summarized in Exhibit 3-A.  The systems shown are grouped by source area.  This information is also incorporated into the District-Wide Water Production Summary Report, presented as Item 4 of the Consent Calendar of this packet.  For comparative purposes, the Annual Water Distribution System Production Summary Report for Water Year 2003 (WY 2003) is provided as Exhibit 3-B.  The report for WY 2003 was revised subsequent to its original presentation at the Board’s March 15, 2004 meeting to account for (1) an emergency transfer of 25.84 AF of water from Cal-Am’s main system to its Ryan Ranch Unit, (2) for 3.01 AF of water that was used for irrigation around Cal-Am’s Carmel Valley wells, and (3) for 0.36 AF of non-revenue water produced during WY 2003. 

 

Production figures for three WDSs -- Bishop, Ryan Ranch, and Hidden Hills Units -- are reported separately from the Cal-Am main system, although Cal-Am owns and operates each system. The Ryan Ranch Unit was acquired and annexed into the Cal-Am system in November 1989.  The Hidden Hills Unit, which formerly reported as the Carmel Valley Mutual Water Company, was acquired and annexed into the Cal-Am system in 1993.  The Bishop Unit, which has been operated by Cal-Am since September 1996, was acquired and annexed into the Cal-Am system in July 1999.  Although water production and delivery values for the Bishop, Hidden Hills and Ryan Ranch Units are reported separately from the values for Cal-Am’s main system in this report, they are included in Cal-Am’s total production in the District-wide Production Summary Report (Exhibit 3-A) as “Cal-Am Wells Outside the Water Resources System”.  In addition, water production from the former Water West WDS, which was acquired and annexed into the Cal-Am service area in 1989 and integrated into Cal-Am’s main system in 1993, is incorporated into Cal-Am's total production and delivery values in this report and in Exhibit 3-A of the District-wide Production Summary Report.  The Rancho Fiesta system is also included as part of the Cal-Am main system.  Water delivery to the Rancho Fiesta system was included because all water used within that system was produced from sources that serve Cal-Am’s main system and the Rancho Fiesta production wells have been inactive for over a decade.  For WY 2003 and WY 2004, all deliveries and connections to Rancho Fiesta customers were incorporated into totals for the Cal-Am main system.  Prior to WY 2003, the 22 connections to the Rancho Fiesta system were listed separately.

 

It should also be noted that the Cañada Woods WDS derives water from wells within and outside the Carmel Valley alluvial aquifer.  Combined production from upland and alluvial sources for the Cañada Woods WDS in WY 2004 was 219 AF, which was 64 AF (41.3%) greater than in WY 2003.  Production from Cañada Woods WDS’s upland sources in WY 2004 totaled 84 AF, representing a decrease of 7.5%, while production from its alluvial wells totaled 136 AF, representing an increase of 108.9%. 

                    

District-wide - Total WDS production within the District for WY 2004 was 16,658 AF.  Of this total, the Cal-Am main system (i.e., not including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for 91% of the water produced by WDSs within the District.  The other 49 systems (i.e., including the Bishop, Hidden Hills and Ryan Ranch Units) accounted for the remaining nine percent of production.  Total WDS production for WY 2004 is 479 AF (3.0%) more than the production reported for WY 2003.  During WY 2004, Cal-Am system production increased by 314 AF (2.1%), while reported non Cal-Am WDS production increased by 164 AF (12.5%), relative to production in WY 2003. It should be noted that Cal-Am’s production total in WY 2004 includes 769 AF that the District produced from its Santa Margarita Test Injection Well and provided to Cal-Am for delivery to customers in its main system.

 

Monterey Peninsula Water Resources System (MPWRS) - Total WDS production from the MPWRS, which includes the Carmel River and its tributaries, the Carmel Valley alluvial aquifer, and the coastal subareas of the Seaside Groundwater Basin, was 15,720 AF in WY 2004.  Total WDS production within the MPWRS increased by 387 AF (2.5%) in WY 2004 compared to production in WY 2003.  More specifically, Cal-Am production in WY 2004 was 314 AF (2.1%) more than production in WY 2003, while combined production from the 15 other active systems within the MPWRS increased by 73 AF (15.9%), relative to production reported for WY 2003.  This comparison includes production from the alluvial wells serving the Cañada Woods WDS.
