i08 GroundwaterLevelChangeSeasonal Points

Change values represent change in groundwater level (elevation) by year and season (fall or spring). Other information on the monitoring location is also included.

Positive values indicate groundwater has risen (groundwater surface elevation has increased) from the early year to the late year, while negative values indicate groundwater level surface has fallen (decreased in elevation ) from the early year to the late year. Water level monitoring locations and measurements used are selected based on measurement date and well construction information, where available, and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers.
