According to the latest update from WaterNSW, it looks like Warragamba Dam is on the verge of overflowing in the near future. The team has issued a warning, stating that heavy rain is expected over the weekend, which could lead to a spill. Currently, the dam is at 99% capacity, with only a 24cm gap left before it reaches its limit.
The Bureau of Meteorology has predicted a catchment rain of 35mm in the next 48 hours, which would result in a daily spill of approximately 40 gigalitres. This amount could increase slightly if the forecasted rain of 60mm over the Warragamba catchment comes to pass. In that case, the dam would spill about 100 gigalitres each day. However, this is a less likely scenario, as it would require more rain than what is currently predicted.
WaterNSW has emphasized that the timing and volume of the spill will ultimately depend on the amount of rainfall the catchment receives. They also mentioned that other dams in the Greater Sydney area, such as Cataract, Nepean, Woronora, Tallowa, Greaves Creek, Medlow Bath, and Middle Cascades, are likely to overflow as well.
Earlier today, Tuggerah Lake had been under a flood warning, but the water levels have since dropped below the minor flood level. Despite this, the community is advised to keep an eye on any flood or weather warnings issued by the Bureau of Meteorology.
It's worth noting that Warragamba Dam has already experienced over 50 spills since 1960. This shows the significance of the upcoming spill and the potential impact it could have on the surrounding areas. So, it's important for everyone to stay informed and prepared for any possible outcomes. Let's hope for the best and stay safe during this period of heavy rain.
