Data and information on total rainfall, percentage of normal, percentage of long-term mean, shorter and long-term groundwater level trends are presented and discussed in this section. Groundwater level data is collected on a monthly basis, interpreted and reported on.

Water Regulation and Use Report: November 2013

Summary

This report coincide with the end of the “dry” season and as can be expected was a general declining trend recorded for the past 6 months. The decline is mostly not significant with almost 60 % of groundwater levels currently higher than the corresponding time last year. Available long-term data indicates that the overall groundwater situation is in a healthy state.

An intense rainfall incident with high rainfall over a short period was experienced in January 2013 over most of the north-north eastern part of the Province which led to some dramatic responses in groundwater levels in that area. The groundwater situation in any area is dependent on local conditions, and deviations from the general trend are always present. The effect of water use and abstraction practices on the groundwater level trend need to be monitored to enable sustainable use.

Water Regulation and Use Report: June 2013

This is the first quarterly status report on monitoring and groundwater levels in the Limpopo for the 2013-2014 year. Groundwater level trends over the past quarter, the past rainy season and the past year is presented and discussed. The impact of the past season`s rainfall on groundwater levels varies in magnitude as well as spatially. Recharge generally took place early in the season with levels starting to decline over the second half of the wet season with 42% of the stations monitored recording lower groundwater levels at the end of the rainy season compared to the situation midway through. After the wet season, higher water levels than before the wet season were recorded at 79% of the stations.

The overall trend in groundwater levels is still a declining one, as has been the case for some time now. Comparison with historic long-term trends indicate this is a normal cycle that may continue for quite a number of years before the next major recharge event ending the cycle. Current water levels reflects a good situation and are generally still well above the worst recorded. It must be borne in mind that this trend cannot continue indefinitely before problems will arise, and it cannot be predicted how long this trend may continue before the next major recharge event occurs. The effect of global warming on climate adds to the uncertainty.

Groundwater is a valuable resource that can sustain the livelihood of a large number of people if scientifically assessed, developed and managed. The unseen nature of the resource prevents the identification of current or future problems that may exist or be expected, at a glance. This unfortunately led to poor understanding, misconceptions, mistrust, mismanagement and ultimately to failure. The management of groundwater by groundwater specialists is essential.
