• Title: GROUND WATER LEVELS IN THE SOUTHERN HIGH PLAINS DESIGNATED GROUNDWATER BASIN
• Year: 2002
• Document Type - Publications and Reports: Ground Water Levels Report

A review of the 2002 measurements as compared to the 2001 measurements reveals that the
following water level changes have occurred since the last measurement period (2001):
water level declines = 30 wells as compared with 43 between 2000 and 2001
water level rises = 46 wells as compared with 23 in the 2000-2001 report
no measured change in water level = 20 wells as compared to 10 in 2000-2001 period.
Arithmetic average of monitored wells. "estimated - thickness including Entrada ss.
