The fires burned 120 acres above dozens of homes that remain in the canyon. Without vegetation to hold back the soil, a quick snowmelt could carry debris down the hillsides and into the creek.
Engineer Douglas Ferguson is coordinating flood prevention work, including building berms and dikes along Canyon Creek.
Ferguson said there’s no way to know how much ash and debris might flow down as spring rains come.
“The wildcard is debris,” said Ferguson. “I can predict what’s going to happen hydrologically and be pretty confident about that. We just have to hope it doesn’t come off too fast.”
This year’s higher than normal snowpack means the flood risk is even greater.
