BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 19-09

Date: March 27, 2019

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
Beaumont Basin through March 18, 2019

Recommendation: No recommendation.

At the present time, there are 16 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. In
mid-summer 2018 a new probe was installed and the security at this location was
enhanced. Water level at this well has been very stable in the last four years
increasing by two feet since August 2015 to the current elevation of 2,142 ft.

✓ At Oak Valley No. 5 the water level declined by seven feet since March 2018, but
is 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 was installed during our last visit.

✓ 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 84 feet over the last 22 months from a low of 2,337 ft.
to 2,421 ft. In the deep aquifer, water level has increased by 54 ft since the
summer of 2016.

✓ 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 two feet over the last three years.
