BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 18-23

Date: December 5, 2018

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
Beaumont Basin through November 15, 2018

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 four months a new probe was installed and the security at this location was
enhanced. Since July 2017 the water level at this well declined by five feet to 2,141
ft in elevation.

✓ At Oak Valley No. 5 the water level declined by seven feet since March 2018 and
it is currently at an elevation of 2,129 ft. This elevation is just two feet lower than
when we started recording water levels in August 2015. Communications cable is
not working and needs to be replaced.

✓ 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 85 feet over the last 18 months from a low of 2,337 ft.
to 2,421 ft., recorded in mid-November 2018. Levels in the deep aquifer have risen
recently to their highest elevation (2,276 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 continues to fluctuate over a 20-
foot band. Conversely, the water level at the Sun Lakes well has fluctuated
minimally over the same period as it decreased three feet over the last three years.
