in the basin to help achieve a better calibrated model, resulting in more accurate
groundwater head distributions. Bettering our understanding of the hydrogeology
of this area will help improve the accuracy of the model and its output.

3.8 Recommendations

The Rules and Regulations, initially adopted in June 2004, were developed with the
understanding that they should be revisited and/or revised from time to time to make sure they
were consistent with the provisions of the Judgment. Revisions to the Rules and Regulations
have been made over the years with the latest revision changing the reporting of Watermaster
activities from a fiscal year basis to a calendar year basis.

Currently, Watermaster is conducting a study to estimate groundwater losses from the basin
resulting from spreading of imported or outside water at selected locations in the basin. The
report is anticipated to be completed in eary 2018.

Watermaster may conduct additional studies in the future in support of:

9 Developing a methodology to account for new yield from capturing local stormwater in
the basin, and

9 Developing a methodology to account for recycled water recharge in the basin.

In preparing this annual report and through the review of previous annual reports, we have
identified a number of issues/activities that should be considered by the Watermaster to
ensure accurate accounting of production, transfers, recharge, and storage. It should be noted
that many of the recommendations provided in this section have been previously documented
in prior annual reports. Our recommendations are as follows:

ƒ Develop a protocol to increase the accuracy and consistency of data reported to the
Watermaster. Watermaster should identify a person and/or entity to be the central
repository for data collection, transfer, and exchange. This person/entity shall be
responsible for the collection and distribution of all groundwater production, water level,
groundwater recharge, and water quality information. Quality control of the data in its
various forms including checks for errors, omissions, and inconsistencies between the
reporting agencies and/or parties should be part of this process.
As indicated earlier, Watermaster should revisit the Rules and Regulations to ensure that its
activities are consistent with the requirements of the Judgment. The following inconsistencies
between guidelines provided in this document and current Watermaster activities were
identified:

ƒ Watermaster has not conducted a meter maintenance program, as required under
Section 3.1 of the Rules and Regulations, to make sure groundwater production is
reported accurately. Individual parties may or may not maintain and calibrate their
production meters at acceptable intervals.
