BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 18-07

Date: March 28, 2018

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Beaumont Basin Water Level Monitoring
Program through March 19, 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.
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 six months was not recorded at this location
despite of the fact that a new water level probe was installed in November 2017.
A second water level probe was installed during our January visit to the site as the
previous probe recorded information was erroneous; however, the new probe was
th
missing during our visit on March 20 , along with the barometric pressure probe.
YVWD staff is currently investigating what happened with these probes. At Oak
Valley No. 5 water level rose over six feet since the water level probe was installed
in March of 2016. The probe and communications cable seem to be working just
fine after the previous cable was stuck in the well for over two months.

✓ 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 85 feet over the last 18 months from a low of 2,337 ft.
to 2,422 ft., recorded at the end of March 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
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.
