- Underwater works using a diver to abandon the existing scour outlet and upgrade the existing outlet pipe
- Extension of the left abutment
- Rip rap erosion protection
- Downstream valve house construction
Outcomes
The successful execution of the project ensures the dam’s resilience to severe floods, safeguarding the public and preserving its historical value.
