Water-table fluctuation may be moderated by nearby springflow. Top line of 1997-99 depth-to-water measurements represents values when a local spring-fed pond was dry. Bottom line of 1997-99 depth-to-water measurements represents values when a local spring-fed pond was full of water. Water-level recovery, possibly due to decreased pumpage in the area, begins in May 1999. |

This well is located on a terrace approximately 40 feet above Beatty Wash, and its open interval is approximately 15 to 35 feet below land surface at and near Beatty Wash. The position of the well's open interval might allow intermittent flow/recharge or ET in the vicinity of Beatty Wash to affect water levels. |
