ERO-019-1060 – Proposal to amend Ontario Regulation 454/96 (Construction) to provide alternative regulatory approval requirements for repairs to existing low hazard wetland dams

The Rudd Dam’s headpond had essentially turned into a large wetland created by over 100 years of sediment accumulating behind the dam, and the shallow pond’s water temperature was no longer viable brook trout habitat.  After the removal of the Rudd Dam the water temperature was reduced and brook trout habitat was made more resilient to a warming climate.  It was also an earthen dam that had already failed once, and the dam owner’s objective was to reduce his risk and liability.
