Watersheds on Fire
Volume 3 Number 5 September/ October 2004

We've all heard about, if not personally witnessed, the catastrophic forest fires in the Southwest in recent years. Loss of homes and habitat is the most distressing result, but effects on the hydrologic system also impact human health and safety. Fire dramatically increases the potential for flash floods and debris flows, both of which cost lives last year. Large ash and sediment loads in streams can fill channels, reduce reservoir capacities, and challenge water treatment systems. In this issue, we look at the impacts to water quality and runoff, as well as emergency response efforts and rehabilitation treatments used, and options for watershed management.
