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
