Groundwater springflows are impacting land and the ability of septic tanks to operate properly. We expect that properties in Deane will be affected by cellar flooding. The next 5 days are forecast to be dry. Groundwater levels are expected to continue rising throughout January, although the rate of rise may slow. The access road from the B3400 into Deane (at Deane Park) may need to be closed in the next couple of weeks. We continue to monitor the forecast and groundwater levels. If you use pumps to help reduce water levels, please ensure that they are operating. We will update this Flood Alert by 18:00 on Wednesday 17/01/2024.

Groundwater
In Deane and Ashe, groundwater levels continue to fall. In the last 7 days, the level at Oakley has reduced by 0.3 m. Groundwater will still be causing some minor impact flooding to fields between Oakley and Deane. It may still be impacting cellars in Deane. Septic tanks will struggle to operate properly. The weather remains dry until Friday (17/04/2020), when rain and then heavy showers are forecast into the weekend. Next week, the weather is similar, with further showers possible at times. It is unlikely that this rainfall will cause groundwater levels to rise. The overall situation will continue to improve, although it will be at least 2 to 3 weeks before groundwater ceases to cause impacts in both communities. However, next week, if the weather outlook remains favourable, and we are confident levels will continue to fall, then we will remove this Alert. We continue to monitor the forecast. We will update or remove this Flood Alert by 15:00 on Wednesday 22/04/2020.
