Starting in early January, Permain Basin Underground Water Conservation District
(PBUWCD) personnel
perform annual depth-to-water level measurements. The data collected
helps the PBUWCD determine the effect of  the pumpage on groundwater levels in the
aquifers, the Ogallala aquifer being the largest  within Howard and Martin counties.  Water
level measurements are made in a network of wells, most privately owned.

A blue vinyl sticker with the observation well number, the depth-to-water level measurement,
and the date of the measurement is affixed to the well equipment or other appropriate surface
near the well site.

Water district personnel measure the same wells in the observation well network each year,
as long as the individual wells provide satisfactory data. The
data collected is used to
determine the annual change in water levels of the aquifers within the district.
