AMBLER PARK, Monterey County — October 2026. A special water-exchange agreement affecting the nine-lot Oaks subdivision near San Benancio Road remains the subject of public quarterly reporting. The Monterey County Environmental Health webpage lists an Ambler Oaks Water Audit Report for the first quarter of 2026 among the records in its online archive. That document concerns the amount of water exchanged with the Ambler Park Water System; it is not the same as the system’s annual drinking-water contaminant report.
Why does a small subdivision have its own water audit?
The county describes a May 6, 2014 agreement with California American Water under which water delivered from the Ambler Park system to the Oaks subdivision is to be offset with an equivalent amount from the subdivision well. The aim is no net transfer of water, accounting for calculated transmission loss. The arrangement is specific to the nine lots; it does not apply to every household served by the Ambler Park utility.
What has to be reported?
According to Monterey County, a qualified engineer must prepare a quarterly water audit showing the volume supplied to the Oaks lots and the water pumped from the Oaks well back into the Ambler Park system. Reports go to the county Environmental Health Bureau with a copy to the Monterey County Water Resources Agency, ordinarily within 30 days after a quarter ends. The agreement also addresses water-meter testing and a county process for responding to discrepancies.
Updated October 30 — what Cal-Am reported for the first quarter
The publicly indexed California American Water April 20, 2026 quarterly audit letter provides numerical details beyond the archive listing: in January–March 2026, the Oaks subdivision consumed 19,517 cubic feet of water while the Ambler Oaks well produced 9,467 cubic feet. The difference for this quarter was 10,050 cubic feet. The letter separately reports that by March 31, 2026, accumulated subdivision consumption exceeded cumulative Ambler Oaks well production by 8,858 cubic feet. The quarterly and cumulative differences must not be confused. The company said it planned to continue pumping to bring production and consumption into balance alongside ordinary well maintenance. These figures come from the utility’s filing and are not proof that regulators completed their review or that a later deficit persisted.
The public archive confirms a first-quarter 2026 audit, but does not by itself establish that Q2 or Q3 reports were never submitted. Readers seeking later balances and any corrective action should request the most recent reports and county correspondence. The accounting does not imply water contamination or a service outage.
How residents can follow the record
The county lists water audits dating back several years, making the issue more transparent than a single press release. Questions worth asking include whether any quarterly discrepancy was identified, whether corrective action was requested, and whether meter tests were performed as scheduled. These are oversight questions—not claims of water contamination or a supply emergency.
