When	Event	Place named	Harm	What the report says
February 1999	Flash Flood	Troy	$1,000,000	A combination of rapid snowmelt and heavy rain caused small streams to flood and roadways to pool with water especially across southern Latah County.
January 2003	Heavy Rain	Troy	$50,000	Up to 3 inches of heavy rain caused a cottonwood tree to fall and crush a Ford Pickup truck and cause a small fire. Power was also out for 4 hours for about 100 residents. The rain also caused minor flooding in the Community Park and the mobile park both in Troy and Bovill.
