SUMMARY:  Staff has prepared a draft Water Production Summary Report of all registered production sources within the District for Water Year 2002 (WY 2002).  WY 2002 includes the period from October 1, 2001 to September 30, 2002.  Preliminary computations indicate that 19,797 acre-feet of ground water were produced from registered wells in the District during WY 2002.  In addition, surface water diversions by the California-American Water Company (Cal-Am) from San Clemente Reservoir totaled 176 acre-feet in WY 2002 and 68 acre-feet of surface water were diverted by other users.  Accordingly, the combined production from surface and ground water sources within the District for WY 2002 is calculated to be 20,041 acre-feet.  In this report, comparisons of Cal-Am and non Cal-Am production in WY 2002 with production in Reporting Year 2001 and with the current District water allocation limits are presented.  


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


BACKGROUND INFORMATION:  Well owners and operators are required to submit water production information from all wells within the District annually.  Well production for WY 2002 was computed by either the Land Use or Water Meter reporting method and is described below.


Reporting Period - To increase consistency, convenience and usefulness of the Well Reporting Program, the period of reporting was changed from the Reporting Year (July 1 through June 30) to the Water Year (October 1 through September 30) in October 2001.  Consequently, this and subsequent Annual Production Reports will be prepared on a Water Year basis.


Number of Wells - Presently, there are 948 registered wells in the District.  Of this total, 652 wells were active and 250 wells were inactive.  Information on the remaining 46 registered wells is not available because the owners have not returned reporting forms.  On the basis of reports received in previous years, staff believes that at least seven of the non-reporting wells were inactive in WY 2002, and at least six represent permits for wells that had not been constructed as of September 30, 2002.  

Data Adjustments - For certain wells, staff had to make estimates of actual production to more accurately quantify water produced during WY 2002.  Data adjustments were required to estimate the water production from 95 wells that either had incomplete water meter records, or reported production for a period longer than WY 2002. 


Production from metered wells with incomplete records was estimated by using generalized, non-Cal-Am monthly distribution factors developed by staff.  In 35 cases, production records were incomplete for the reporting period because water meters were installed or repaired after the start of WY 2002, or because the reported production was for a period shorter than WY 2002.  By applying monthly distribution factors, staff was able to reasonably estimate the percentage of production that was not reported for each of these wells, which was then added to the annual total for those wells. 


For 60 cases in which production was reported for a period longer than WY 2002, estimates of the amount of over-reported production were made based on the monthly distribution factors.  These amounts were then deducted from the reported totals.  In seven additional cases, production for wells with non-functioning water meters was estimated based on historical records.  Of those seven, four meters have been repaired or replaced.


District-wide Production - Preliminary production values for WY 2002 are summarized by reporting method, reporting status, and source area in Exhibit 5-A.  For comparison, production values for RY 2001 are presented in Exhibit 5-B.  The aquifer subunits and source areas are shown in Exhibit 5-C.  The volume of water produced from various source areas within the District in WY 2002 is shown in Exhibit 5-D.  The number of active non-Cal-Am wells and the volume of water produced by each reporting method for WY 2002 and RY 2001 are compared in Exhibit 5-E.


District-wide, total water production increased by 1,314 acre-feet (seven percent) in WY 2002 compared to production in RY 2001.  Specifically, ground water withdrawals increased by 1,249 acre-feet (seven percent), while surface diversions increased by 65 acre-feet (36 percent) during WY 2002.  It should be noted that 68 acre-feet of non Cal-Am surface water diversions were reported in WY 2002, an increase of 41 percent from RY 2001.  Cal-Am surface diversions from San Clemente Reservoir increased 45 acre-feet (34 percent).


Within the Monterey Peninsula Water Resources System (MPWRS) - The MPWRS includes the Carmel River and its tributaries, the Carmel Valley alluvial aquifer, and the coastal subareas of the Seaside Basin.  Overall water production within the MPWRS in WY 2002 increased by 640 acre-feet (four percent) compared to RY 2001.  Specifically, Cal-Am production in WY 2002 increased 473 acre-feet (three percent), while non-Cal-Am production increased by 167 acre-feet (six percent) compared to the previous year.  Cal-Am production in Carmel Valley increased 258 acre-feet (two percent), and Cal-Am production from the coastal subareas of the Seaside Basin increased 215 acre-feet (seven percent). Non-Cal-Am production from Carmel Valley increased by 203 acre-feet (ten percent) compared to the previous reporting period, and non-Cal-Am production from the coastal subareas of the Seaside Basin decreased 36 acre-feet (four percent).

Water Allocation Program
- With respect to the District's Water Allocation Program limits, Cal-Am production from the MPWRS in WY 2002 was 14,611 acre-feet, or 3,030 acre-feet (17 percent) less than the Cal-Am production limit of 17,641 acre-feet that was established with the adoption of Ordinance No. 87 in 1997.  Non-Cal-Am production within the MPWRS in WY 2002 was 3,216 acre-feet, or 170 acre-feet (six percent) more than the non Cal-Am production limit of 3,046 acre-feet established by Ordinance No. 87.  Although non Cal-Am production from within the MPWRS was above the established limit, the combined production from both Cal-Am and non Cal-Am sources in WY 2002 was 17,827 acre-feet, which is 2,860 acre-feet (14 percent) less than the 20,687 acre-feet production limit set for the MPWRS.  A comparison of reported water production from within the MPWRS in WY 2002 relative to the Water Allocation Program limits is shown in Exhibit 5-F.


Lastly, it should be noted that 99 percent of the ground water production within the District was reported by the water meter method in WY 2002.  In addition, 95 percent of the registered well owners in the District reported their water production in WY 2002.
