The site for the dam was considered unsuitable by some, but the Rural Services
deemed the site usable based on geological and hydrological studies. The rock
foundation appeared to be watertight. The left abutment (looking upstream) is
rock; a concrete wing wall had to be constructed on the right abutment for
better interaction with the arch. /td> |
