consensus among the Members of the Watermaster to include this condition, and
Member Zoba suggested having RMC agree to that condition in writing, with the
assistance of Legal Counsel Montoya. He also requested a copy of the written request
from RMC to Mr. Harder.

Legal Counsel Montoya suggested that the Watermaster have RMC submit a Public
Record Act request for the data, to which the Watermaster could respond accordingly.
The Members of the Watermaster voiced their agreement with this suggestion.

B. Report from Legal Counsel - Thierry Montoya, Alvarado Smith

Legal Counsel Thierry Montoya reported that he had prepared an amendment to the
contract with ALDA Inc. and had emailed it to the Watermaster Members for their
comments. He noted that if there were no comments the agreement is ready for
signature.

VI. Discussion Items

A. Overview of the Issues Associated with the Estimation of Groundwater Storage
Losses due to Supplemental Water Recharge [Memorandum No. 17-12, Page 7 of
11]

Recommendation: No recommendation.

Mr. Harder presented a synopsis of the methodology, or lack thereof, of twelve
groundwater management basins in California in estimating groundwater
storage losses. He concluded his synopsis by suggesting that in his research,
he had found that with the exception of a couple of groundwater management
basins, storage losses are not addressed as technically or in as much detail as
he had expected.

Mr. Harder went on to discuss the unique hydrogeological issues faced by the
Beaumont Basin in developing a methodology for accounting for groundwater
storage losses, then provided a few conceptual scenarios for addressing those
issues in the development of a model.

Several Members voiced their support of a technically defensible model to
estimate groundwater storage losses as opposed to applying a flat percentage
of groundwater storage losses to all storage accounts.

Engineer Blandon asked for clarification from the Watermaster in terms of
whether a line item proposal for developing a sound model for estimating
groundwater storage losses would be desired. The consensus among the
Watermaster was that such a proposal would be acceptable and Engineer
Blandon confirmed that one would be presented at the following meeting.
