The delays in completion caused severe financial difficulties to the irrigation companies and eventually the State had to take over the debts of the irrigators and £2,350,000 had to be written off. It was completed in 1922 and only filled by 1928, the delay a result of extensive drought.

The original dam was designed to store 142 million m. The high sediment yield of the
Sundays River meant that sediment delivery into the reservoir basin quickly reduced its capacity. The dam wall was raised by 1.5 m in 1935 and again by 5.8 m (total capacity 327,628,072 m) in 1951/52 to cope with the

Sundays River Irrigation Board was established and took over the project from the
