Water table levels on 1 November 2018 were uneven across different regions.
Approximately one third (28%) of all water tables were at moderately high to very high levels while around half (51%) were at moderately low to very low levels. The remaining fifth (21%) were at average levels. The situation is not particularly encouraging for the period, since the initial impact of the winter recharge can generally be observed at this time. The low-water period is still continuing and the effects of winter recharge are overdue.
Trends in water table levels
Once again, the general trend in water table levels this month reflects the low-water period, with levels stable in only 17% of the measurement points. The situation has changed very little in relation to last month (11%). However, the number of points with rising levels (22%) has increased (8% last month). At the same time, the number of points showing a downward trend (61%) has decreased (81% last month).
The general status of the water tables on 1 November 2018 reflects the transition between the low water period and the start of the winter recharge. The start of the winter recharge is a little late, but an improvement in the situation is expected over the coming months.
