Basin Groundwater Levels Groundwater levels in the Bunker Hill, Rialto -Colton, and Riverside North basins are continuing to show a long-term declining trend, while groundwater levels in the Riverside South Basin remain relatively stable as shown in Figure 6. Water levels decreased by 6 feet in the Bunker Hill Basin. Water levels in the Rialto -Colton Basin increased by 10 feet as compared to July of last year. This level increase may be due to decreased pumping activities in the local area near the key monitoring well.
