following account is based on Lawson and Burton (1990), Lawson et al. (1992) and
Russo et al. (1985).
The dam is a concrete gravity structure 38 m high and 876 m long. Most of its length
comprises 34 monoliths which mainly cross the 600 m wide river bed. The site is formed
almost entirely of welded tuff, which is fresh and extremely strong. Near-horizontal sheet
joints are exposed over much of the river bed (

), and dipping sheet joints
