BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 18-19

Date: October 3, 2018

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
Beaumont Basin through September 25, 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 two 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 four feet to
2,142 ft in elevation.

✓ At Oak Valley No. 5 - The water level probe stopped recording on March 20, 2018,
but we were not aware of this condition since we had difficulties removing the probe
from the well. The probe was removed during our last visit and the data
downloaded; however, the data stored over the last six months proved to be
inconsistent at best. A new probe will be installed at this location.

✓ 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
2,422 ft., recorded at the end of July 2018. Levels in the deep aquifer have risen
recently to their highest elevation (2,274 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 one foot.
