Fullerton Pollan Reservoir was completed in 1997 with a capacity of 4.6 Mm~3 and a yield of 33 Ml/d to municipal supply and compensation. It has a central conventional concrete gravity section flanked by earth core- rockfill embankments. The dam is 22.5 m high above lowest foundation. The concrete dam incorporates the spillway, fish lifts, draw-off and compensation release pipework. Thick deposits of till and peat deep blanket the site. The till was used for core material while rockfill for the shoulders was excavated from an on-site quarry. The rock foundation was grouted using the GIN method. The concrete mix designs for the dam made use of cement replacement to minimise thermal cracking. The performance of the dam over its first five years has followed expectations.
