BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 17-27

Date: December 6, 2017

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
Beaumont Basin through November 27, 2017

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.
At YVWD No. 34 the water level is fairly stable; it has increased a mere three feet
over the last 2 years. Data for the last four months was not recorded at this location
as the probe is not working properly. A new probe was installed during our
November visit. Conversely, water level at Oak Valley No. 5 rose over five feet in
the March 2016 to November 2017 period. Data for the last six months was not
available as the probe was stuck in the well and the communications cable was
non-operational; however, during our November visit we were able to dislodge the
probe and pull it out of the well. The probe was reinstalled with a new
communications cable.

✓ 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 increase close to 80 feet over the last 18 months from a low of 2,337 ft.
to 2,416 ft., recorded at the end of November 2017. Levels in the deep aquifer
have risen recently to their highest elevation (2,260 ft) since the summer of 2015.

✓ 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
cemetery grounds. The Water level at this well was not available for the last two
months as cemetery personnel were not present to open the gate to the well. The
water level at this well has fluctuated over a 20-foot band over the last two years.
Conversely, the water level at the Sun Lakes well has fluctuated minimally over
the same period as it decreased two feet.
