Population over time

2 figures

Coulee Dam grew from 1,098 to 1,211 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.

Regional context, not property-specific evidence. The National Weather Service names Coulee Dam in 3 storm reports between 1996 and 2014: 2 thunderstorm wind, 1 flash flood. No death or injury is recorded in these reports. 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.

WhenEvent Place namedHarm What the report says
June 1996Flash FloodCoulee Dam$380,000no account filed
August 2013Thunderstorm WindCoulee Dam$100,000Numerous trees and power lines were downed within and around Coulee City. Downed trees blocked roads, damaged vehicles, boat trailers, street signs, and homes. A large tree fell across State Route 155 closing the highway for over three hours. The roof was partially torn off at the Coulee Dam Casino. Several signs were also damaged at the casino. Due to the roof damage, moderate rains trailing behind the wind resulted in water damage to portions of the casino and offices. The Spring Canyon RAWS located three miles southeast of Coulee Dam clocked a wind gust of 65 miles per hour.
August 2014Thunderstorm WindCoulee Dam$10,000IMET stationed in Nespelem Fire Camp received winds between 50 and 60 mph along with blowing dust. The winds knocked trees down, tossed boxes, tents, tarps, and signs around fire camp. Several porta potties were knocked down as well. The storm weakened as it reached Brewster, Okanogan, and Omak. These areas received wind gusts near 35 mph which blew down small branches causing some isolated power outages in the community of Twisp.
