Population over time

2 figures

Winthrop grew from 394 to 504 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate, and an estimate published within five years of a census is left out. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

WhenEvent Place namedHarm What the report says
July 2001WildfireWinthrop4 killed, 4 hurtThe "Thirtymile" wildfire was in the mop-up stages on July 10 when excessively hot and dry conditions that afternoon caused the smoldering fire to blow up. The fire came roaring back to life, quickly spreading from 25 to 2,500 acres in just three hours. The quickly-spreading fire overran a group of 14 firefighters, causing members of the group to deploy emergency shelters. Four members of the group perished (direct), and four others were hospitalized with injuries. The Thirtymile fire was contained on July 23 after burning a total of 9,300 acres. The cost of fighting this fire exceeded $4.3 million.
May 2018FloodWinthrop$100,000Spring time snow melt caused the Chewuch River near Winthrop to rise and cause minor flooding during the second and third weeks of May. Roads and fields along the river were inundated and a few homes suffered yard inundation and first floor minor flooding.
July 2016Debris FlowWinthrop$25,000The Forest Service reported that heavy rain from thunderstorms resulted in a road washout on Ramsey Creek Road. A one mile stretch was blocked with mud and debris. The time of the event was estimated.
June 2004Flash FloodWinthrop$10,000During the afternoon of June 27th a thunderstorm dumped heavy rain over the upper Chewuch River north of Winthrop. A mud slide resulted with a two acre stretch of mountain side sliding into the Chewuch River. This caused the river to change course and inundate the forest road along the river.
July 2023Flash FloodWinthrop$5,000Multiple reports of flash flooding two miles Northwest of Winthrop. Mud and debris on road reports for West Chewuch Road, Highway 20, and Wright Road. Methow Valley Airport recorded 0.9 of an inch fell in an hour and half.
June 2011FloodWinthrop$3,000A combination of landslides and flooding along creeks and rivers resulted in the closure of numerous campsites within Perygian State Park through the first two weeks of June. Damage costs were estimated based on an average loss of revenue from closed campgrounds.
April 2018Debris FlowWinthrop$2,000A debris flow was reported blocking West Chewuch Road.
