BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 19-02

Date: February 6, 2019

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
Beaumont Basin through January 22, 2019

Recommendation: No recommendation.

At the present time, there are 14 monitoring wells collecting water level information on an
hourly basis at various locations throughout the basin. In addition, there are two
monitoring probes collecting barometric pressures at opposite ends of the Beaumont
Basin. The location of active monitoring wells is depicted in the attached Figure No. 1.

Water levels at selected locations are depicted in Figures 2 through 6 and are described
as follows:

✓ Figure No. 2 – Water levels at YVWD Well No. 34 and Oak Valley Well No. 5 are
considered representative of basin conditions in the Northwest portion of the basin.
Water levels at YVWD No. 34 were not recorded between July 2017 and July 2018
due to several reasons including faulty equipment and repeated vandalism. Over
the last six months a new probe was installed and the security at this location was
enhanced. Water level data was corrected to take in consideration the new
communications cable installed. Previously a drop of five feet in water level was
reported; however, this was associated with erroneous data. Water level at this
well has changed less than one foot since July 2018. Current water level elevation
is at 2,142 ft.

✓ At Oak Valley No. 5 the water level declined by seven feet since March 2018, but
is currently showing signs of recovery and it is currently at an elevation of 2,132 ft.
This elevation is one foot higher than when we started recording water levels in
August 2015. A new communications cable has been ordered and will be replaced
before the next meeting.

✓ Figure No. 3 – Two of the Noble Creek observation wells are presented in this
figure representing the shallow and deep aquifers. In the shallow aquifer, the water
level has increased close to 87 feet over the last 20 months from a low of 2,337 ft.
to 2,424 ft. In the deep aquifer, water level has increased close to 36 ft since
monitoring began in the summer of 2015 and it is currently on an upper trend,

✓ Figure No. 4 – Southern Portion of the Basin. Water level at the Summit Cemetery
well is highly influenced by a nearby pumping well that is used to irrigate the
