BEAUMONT BASIN WATERMASTER

MEMORANDUM NO. 17-20

Date: August 2, 2017

From: Hannibal Blandon, ALDA Inc.

Subject: Status Report on Water Level Monitoring throughout the
Beaumont Basin through July 24, 2017

Recommendation: No recommendation.

At the present time, there are 12 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. Conversely, water level at Oak Valley No. 5 rose over five
feet in the March 2016 to May 2017 period. Data for the last two months could not
be downloaded from the field probe 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 over 60 feet over the last year from a low of 2,337 ft. to a
current level of 2,398 ft. Levels in the deep aquifer have fluctuated within a 10-
foot band over the same period.

✓ 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 has fluctuated over a 20-foot band
over the last two years. Conversely, the water level at the Sun Lakes well has
fluctuated minimally over the same period as it decreased two feet.

✓ Figure No. 5 illustrates levels at three wells owned by the City of Banning in the
Southeast portion of the basin. While water level at the Old Well No. 15 (Chevron
Well) has been fairly flat over the last two years, a somewhat significant and steady
decline, close to 18 feet, has been recorded at Banning M-8. Levels at Banning
M-9 have stayed within a 10-foot range.
