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.

✓ 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 summer 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 is slightly lower. Water level at BCVWD No. 25 seems to be in
sync with BCVWD No. 2 based on the short recording period of only six months.

✓ Figure No. 6A illustrates the influence of the recently activated BCVWD No. 3 on
th
th
water levels at Well No.2. during the July 7 to July 10 period. Well No. 3 is
located approximately 300 ft. to the south of Well No. 2. During this 3-day period
a decline of approximately 10 ft. in water elevation was recorded at Well No. 2
followed by a steady revovery.

✓ Figure No. 6B illustrates water level fluctuations at BCVWD No. 25 as a result of
TOU scheduling. While Figure 6 depicts average water levels over a 24-hour
period, an hour interval is used in Figure 6B. This latter figure indicates that water
levels quickly recover to near static levels once Well No. 25 is turned off during
On-Peak hours. A decline of approximately 65 ft. has been recorded at this well
during operational hours.

New Equipment Installation

✓ YVWD Well No. 34 – A temporary probe was installed at this well during our May
visit as we waited for the right length communication cable to arrive from Solinst.
This probe was stolen/destroyed by vandals who may have had access to the on-
site padlock. A new 300 ft communications cable and probe were installed to
monitor water levels. A new barometric probe was also installed to monitor
barometric pressure in the northern portion of the basin. A new padlock was
installed to minimize future acts of vandalism.
