Denver -- U.S. forest managers say threats to watersheds from fire-prone dying forests are so severe they need help from local water utilities, ski resorts and others.
The crisis, experts say, is a beetle epidemic that has killed more than 17 million acres of national forest, The Denver Post reported Wednesday.
The Forest Service spends nearly $1 billion a year to clear and treat beetle-ravaged forests, but it is looking for help, the newspaper said.
"The federal government doesn't have enough resources to deal with this," said Harris Sherman, the U.S. Department of Agriculture's undersecretary for natural resources and environment.
The problem is erosion and sediment, which can clog reservoirs and water delivery systems, the Post said.
