Haliburton Updated Floodplain Mapping Project

The County of Haliburton has partnered with the Ganaraska Region Conservation Authority (GRCA) and Kawartha Conservation to complete floodplain mapping for the Gull and Burnt Rivers.

This work also includes mapping of high water levels for numerous lakes within each watershed.

Floodplain mapping helps to identify areas that may be at risk of flooding during severe storms and is an important tool for land use planning and emergency preparedness.

This project is being funded in part by the Flood Hazard Identification & Mapping Program (FHIMP).
