Description
Groundwater levels recorded at many key monitoring bores within the Alice Springs Town Basin
aquifer are (as of April 2019) at their lowest levels in recent history, and have declined below their
previous low levels recorded during 2008-09 at many locations.
The Alice Springs Water Allocation Plan (WAP) 2016-2026 (DLRM 2016) states that groundwater
levels in the Todd River corridor of Alice Springs must not be permitted to decline below 8 m bgl
(below ground level) to protect river red gum health. This situation last occurred in 2008-09 when
Power and Water Corporation (PWC) ceased groundwater extraction from their “River sector”
productions bores because groundwater levels fell below an elevation specified in their extraction
licence.
The purpose of this report is to present recent monitoring and survey data relevant to the most recent
groundwater levels recorded in the Town Basin aquifer.,
