Storms near this property

16 since 2002

Regional context, not property-specific evidence. The National Weather Service names Stanley, the town this property stands in, in 16 storm reports between 2002 and 2025: 8 thunderstorm wind, 5 flood, 2 wildfire, 1 debris flow. The reports record 3 injuries. Each account below is quoted exactly as the forecast office filed it, from the NOAA Storm Events Database, and each date opens the federal record of that event.

When	Event	Place named	Harm	What the report says
July 2008	Thunderstorm Wind	Stanley	3 hurt, $420,000	Microburst winds estimated to be as high as 95 mph did extensive damage at the Redfish Lake campgrounds. Up to 1,000 Lodge-pole pine trees were uprooted with several snapped 3 to 5 feet above ground level. Twenty to forty Douglas Firs uprooted as well. The average diameter of the snapped Lodge-pole pine trees was 5 to 14 inches and the average Douglas Fir diameter was 10 to 24 inches. At the Glacier View Campground, 3 people camping were injured including one sustaining a broken leg. All of those injured were taken by ambulance to care facilities. Campground facilities were damaged with multiple vehicles damaged from the trees falling as well.
May 2017	Flood	Stanley	$3,500,000	The Salmon River in Salmon reached moderate flood stage in May and this caused flooding from the headwaters of the Salmon south through Challis into Custer County. Trail Creek, Valley Creek, Garden Creek and Antelope Creek all overflowed banks with flood warnings throughout the month continuing in Custer County. Major damage occurred to backcountry roads and campgrounds. Significant agriculture damage occurred due to flooded fields. Road and bridge damage required significant repair along with significant USFS infrastructure damage. The cost of damage and flood protection rose above 3 million dollars for the month.
June 2017	Flood	Stanley	$900,000	The Salmon River in Salmon had reached moderate flood stage in May and stayed at flood stage into June and this caused flooding from the headwaters of the Salmon south through Challis into Custer County. The Yankee Fork and East fork of the Salmon River flooded along with Thompson Creek, Squaw Creek, Kinnikinic Cerek and Bayhorse and Garden Creek. Most side tributaries recorded record flows. The Valley Creek in Stanley flooded with the peak flow on June 5th. The Big Lost River at Howell Ranch recorded its second highest peak ever and the Big Lost below Mackay Dam reached minor flood stage as well with peak flows continuing through the end of June. Homes, businesses, roads and bridges continued to suffer damage due to the flooding along with agricultural fields and USFS infrastructure.
February 2017	Flood	Stanley	$195,000	The combination of record or near record snows in December and January with a warmup in February caused sheet flooding and some ice jam flooding as well. An ice jam on the Lost River near Darlington caused flooding to some homes on that river. Extensive road damage occurred throughout the county with the snow and snow melt combinations. And the warmup aided in weight on roofs and collapses in many cases throughout Custer County. The county declared a county disaster due to the damages.
