✓ 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 22 feet, has been recorded at Banning M-8. Levels at Banning
M-9 have fluctuated within a 15-foot range during the same period.

✓ Figure No. 6 illustrate recorded water level at BCVWD No. 2. Over the last two
years, the level at this well has increased by over 20 feet topping in May 2017 at
an elevation of 2,218 ft. The level at this well has declined by ten feet over the last
four months.

Troubleshooting Issues

The following malfunctioning issues were encountered during our July 25, 2016 field visit:

✓ YVWD Well No. 34 – Communication cable needs to be replace and probe did not
record any information over the last two months. A new probe was installed and
a replacement cable has been ordered.

✓ Sun Lakes Well – Communication cable was replaced with a new cable; however,
communications continue to be difficult at this site. Data was downloaded by
pulling the probe out of the well. A new cable has been ordered to replace existing
cable.

✓ Oak Valley No. 5 – Communications cable is not working at this time and may need
to be replaced. In the past, data was downloaded by pulling the probe out of the
well; however, the probe is now stuck and could not be pulled out.

New Potential Monitoring Sites

BCVWD Well No. 25, located in the central/eastern portion of the basin has been
identified as a potential candidate to monitor water levels. While this well is a pumping
well, it is typically not used between 12:00 Noon and 6:00 PM to take advantage of lower
energy rates. A six-hour rest on this well, while not ideal, could be used to establish static
levels and aquifer response in the area. Considering that pumping levels are
approximately at 550 ft, the probe could be installed at 650 ft below ground. This location
is approximately 50 feet above the current pump setting.
