When	Event	Place named	Harm	What the report says
September 2013	Flash Flood	Leavenworth	$40,000	Flash flooding and debris on Fourth of July Creek above Icicle Creek closed off National Park Road 76. Many campers were stranded above where the flash flood occurred until the road was cleared of debris. Damage costs were estimated.
January 2021	Debris Flow	Leavenworth	$20,000	A hillside along State Route 2 began slowly sliding, striking the Department of Transportation guardrail, and partially blocked the eastbound lane. The mudslide was triggered by already saturated soil and wet snow.
March 2011	Flood	Leavenworth	$10,000	A blocked railroad culvert resulted in water flooding out onto Chumstick Highway near Freund Canyon about 1.3 miles north of Leavenworth. The water was about a foot deep across the road for a brief period resulting in its closure. Parts of the road were damaged by the flowing water.
January 2015	Flood	Leavenworth	-	Newspaper posted two photos and narrative on their Facebook page showing a structure used to store rafting equipment being flooded. Comments to the post note that the flooding is from rain, slush and melting snow and ice as the structure is in a natural depression near a mountain.
December 2015	Debris Flow	Leavenworth	-	An emergency manager reported a mudslide on SR-2 just west of Leavenworth, WA. The road was closed and the flow was estimated at 10 feet deep.
November 2006	Flood	Leavenworth	-	Very heavy rain led to flooding on Icicle Creek near Icicle Island.
November 2006	Flood	Leavenworth	-	Very heavy rain led to rapid rises on the Wenatchee River, with major flooding of fields on East Leavenworth Road.
