✓ 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 20 feet, has been recorded at Banning M-8. Levels at Banning
M-9 have fluctuated within a 10-15 feet 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, with a slight recovery in the last two months.

Troubleshooting Issues

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

✓ YVWD Well No. 34 – Both communication cable and probe were not working at
this well. The probe was replaced, but the 400 ft communication cable was not
replaced at this time; a new 400 ft cable needs to be ordered for this site.

✓ Sun Lakes Well – A new 200 ft communication cable was installed at this well and
it seems to be working fine.

✓ Oak Valley No. 5 – Over the previous two visits, the water level data could not be
downloaded from the probe because of a faulty communications cable; in addition,
the probe was stuck inside the well and could not be removed. During our
November visit, the probe was finally removed from the well and a new 200-ft
communications cable installed. This probe should not be pulled from the well
because of potential damage to the communications cable.

New Monitoring Sites

A new water level probe was installed at BCVWD Well No. 25, located in the
central/eastern portion of the basin. The probe sits at 650-ft below ground in this pumping
well. Static level at this well was measured at 493 ft below surface while pumping level
is in the mid 500s.

In addition, SMWC Well No. 4 in the northwest portion of the basin was considered for
installation; however, the observation conduit was much too small for the monitoring
probe to fit.

Potential New Monitoring Sites

Potential new monitoring sites include:

• Sharondale Home Owner Association wells
• Rancho Calimesa Mobile Home Park
• Desert Lawn
• Sunny Cal Ranch Area
