Lewis shared the long-term trends and changes in groundwater levels
from December 2017 to December 2018. On the western side there was
a decline of one to five feet; on the eastern side there was an increase
of one to five feet. Mr. Jaggers pointed out that the model considered a
certain amount of recharge, and BCVWD has added substantially more.

Water quality data is garnered from the California Department of Public
Health and the Beaumont Basin Management Zone Maximum Benefit
Report by Dudek, Blandon explained. The Dudek data will be
incorporated when available later this month. Over the five-year
analysis, none of the primary state and federal standards were
exceeded. Overall, the water quality is very good, he concluded.

The recommendation for a policy to account for groundwater storage
losses is being carried forward from previous reports. In 2018, a study
was conducted on basin storage to estimate how much water is lost
based on imported water spreading activities, which may be used to
develop a policy. Also suggested is a process to assure accuracy and
consistency of data reporting, such as regular calibration and
maintenance of water meters.

Mr. Blandon indicated he would incorporate comments from BCVWD and
YVWD in the next draft.

IX. Topics for Future Meetings

A. Development of a methodology and policy to account for new yield
from capturing local stormwater in the basin

B. Development of a methodology and policy to account for groundwater
storage losses in the basin resulting from the spreading of additional
water sources

C. Development of a methodology and policy to account for recycled
water recharge

D. Develop a protocol to increase the accuracy and consistency of data
reported to the Watermaster

E. Develop a policy to account for transfers of water that may result when
an Appropriator provides water service to an Overlying Party
F. Discussion of Overlyer return flow credit and how it might be managed

X. Comments from the Watermaster Committee Members

Member Zoba commented that he appreciates the dialogue. The Committee
has been at this for 15 years, he said, and he appreciates working together.
There is a new percolation test and monitoring wells going in off Singleton near
