Drain 222 Sills Remediation

The Otago Regional Council (ORC) currently maintains a number of floodbanks and associated structures (including rural bridges) across the Otago region. The bridge where the sills are located, is on Crown land in the Clutha Area. This channel (Drain 222) and the adjacent flood bank form part of the Lower Clutha Flood Protection and Drainage Scheme.

Bridge 4 on Drain 222 has stop logs for the managing of the drain residing on it. Their function is to assist in maintaining consented water levels in lake Tuakitoto up stream. Currently these are manually operated depending on the season or water levels. A design has been completed in conjunction with the Otago Regional Council field team that replaces the old stops logs with new, that can be raised and lowered by winching from the bridge. They currently get lifted off their mounts manually and left on the bank when not in use.
