Encyclopedia
Carcoar Dam is a concrete arch dam
with a free overflow type spillway across the Belubula River
6 kilometres (3.7 mi) upstream of Carcoar
. It is 57 metres (187 ft) high and 187 metres (613.5 ft) long and holds back 35,800 megalitres of water when at full capacity. The dam uses a free-flowing spillway which is capable of discharging 105,000 megalitres of water per day.
Water from the dam is released directly into the Belubula River which is used by irrigators downstream of the dam.
The dam is unique in that its wall is not only curved from side-to-side but also from top to bottom.
government assisted to establish wetlands at Carcoar Dam in an effort to control blue-green algae which had made the dam unusable for recreation and made the water discharged from the dam unusable, even for domestic animals. The purpose of the wetland was to act as a nutrient sink which could capture nutrients prior to them entering the reservoir.
