Save water

Evaporation – how much water do I lose?

Evaporation is the single largest cause of water loss.

Every square metre of water surface loses about 8 litres to evaporation every day in the warmer months.

This means that even a small farm dam of 1,000 square metres will lose 8,000 litres per day. A 100 hectare dam loses 8 megalitres per day, or 56 megalitres every week

The table shows evaporation losses for typical dam sizes ranging up to 100 hectares.

Dam Area Evaporation At 8 mm Per Day*
Daily Weekly
1,000 sq m 8,000 Lt 56,000 Lt
5,000 sq m 40,000 Lt 280,000 Lt
1 hectare 80,000 Lt 560,000 Lt
5 hectares 400,000 Lt 2.8 ML
20 hectares 1.6 ML 11.2 ML
100 hectares 8.0 ML 56.0 ML

*Typical daily evaporation during the warmer months in most parts of Australia
