Nevada has two main types of flooding.  River Valley Flooding occurs in valley bottoms during large winter storms, when prolonged heavy rain falls on mountain snow packs.  The New Year’s flood of 1997, which caused tens of millions of damage in the Truckee, Carson and Walker River watersheds, are examples.

Alluvial Fan Flooding occurs along small creeks and usually dry “washes” that emerge from the bottom of mountain canyons.  Alluvial fans are susceptible to violent flash floods shortly after intense summer thunder showers.  These types of floods are unpredictable.  During a flash flood, former channels can become clogged with rocks and sediment, sending deep, fast-moving floodwater down into new locations.
