"After the Waldo Canyon Wildfire - The Williams Canyon Project"
When the Waldo Canyon wildfire swept through the mountains north of Manitou Springs in June 2012, Williams Canyon was one of several severely burned drainage basins. The 2.7 square mile Williams Canyon watershed drains into Manitou Springs and, in 2013, several flash flood events occurred down Williams Canyon and into the town.
The help mitigate the effects from the increased flood risk, funding from several federal and state agencies was used for two major phases of the Williams Canyon Project: Phase 1 involved constructing approximately 1,000 feet of improved channel with structural concrete and soil nail walls in the steep, narrow mouth of the canyon, removal of two residential structures to create space for a debris basin and installation of three steel nets for capturing flood debris. Phase 2 involved extending the channel improvements for approximately 500 additional feet through an existing residential neighborhood and included removing two additional residential structures.
