Project Description Summary

This involved the installation of one sill breach: 25m, invert at 1.7mNN (-0.7MHW); breach and summer dike enforced (i.e. breached dike will not be allowed to erode so as to not affect navigation) . As part of this scheme a lagoon area was excavated - mostly 0.2-0.5m deep, with several deeper areas (>2m) for fish refuge.
