✓ 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 23 feet, has been recorded at Banning M-8. The probe at Banning
M-8 was removed during our visit in late January 2018 as there seems to be an
obstruction in the well at a depth of approximately 350 ft below ground. City staff
has indicated that the pump at this well will be pulled in the next two months at
which time we may have an opportunity to use this well again. Water level at
Banning M-9 has fluctuated within a 10-15 feet range during the same period.

✓ Figure No. 6 illustrate recorded water level at BCVWD No. 2 and the new
monitoring well BCVWD No. 25. Over the last two years, the level at BCVWD No.
2 has increased by over 20 feet topping in May 2017 at an elevation of 2,218 ft.;
current water level elevation is at the highest point since the monitoring program
began. The level at this well declined by ten feet before recovering again over the
last six months. Water level at BCVWD No. 25 seems to be in sync with BCVWD
No. 2 based on the short recording period of only four months.

Troubleshooting Issues

The following malfunctioning issues were encountered during our March 19, 2018 field
visit:

✓ YVWD Well No. 34 – Both the water level probe and barometric pressure probe
are missing from this well. YVWD staff is currently investigating this issue. While
there is a possibility that both probes felt to the bottom of the well, this condition is
highly unlikely. If the probes are found, a new 300 ft communications cable will be
needed as the current cable was not working properly. If the probes are not found
a new barometric pressure probe will need to be purchased for this location in
addition to the 300 ft communications cable.

✓ Sun Lakes Well – A new 200 ft communication cable was installed during the
November visit and it is working fine as we are now able to communicate with the
probe.

✓ Banning M-8 – The water level probe was removed from this well during our
January visit since the well is obstructed at approximately 350 feet below ground.
City staff has indicated that the existing pump at this well will be pulled in the next
two months; this will present an opportunity to determine the nature of the below
ground obstruction and the potential installation of a new water level probe to
continue using this well for monitoring purposes.

✓ Barometric Probe at Banning M-9 stop working on New Year’s Day. Probe was
th
reset after the regular Board meeting in February 7 , 2018 and is currently working
fine.
