BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 18-15

Date: August 1, 2018

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
th
Beaumont Basin through July 24 , 2018

Recommendation: Pending.

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 have not been monitored since June 2017 due to a
combination of equipment malfunctioning (communication cables and monitoring
probes) and vandalism. Earlier in the year the water level probe and barometric
probe were stolen from the site; a new communications cable and water level
probe were installed during our May 2018 visit, but they were also vandalized and
stolen. Upon consultation with YVWD’s operations staff, a new padlock was
installed at the site and a new water level and barometric pressure probes
installed.

✓ At Oak Valley No. 5 water level rose over six feet since the water level probe was
installed in March of 2016; however, we have not been able to communicate with
the probe over the last four months. While a new communications cable could be
installed at this well, we had difficulties removing the existing cable from inside the
well in the past. Probe continues to record water levels at existing well.

✓ 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 (2,271 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
