2000: Heavy snow of 6 to 9 inches fell across parts of northeast South Dakota, causing travel difficulties and school closings. Some snowfall amounts included 6 inches at Britton, Roy Lake, Webster, Waubay, Summit, and Wilmot; 8 inches at Columbia and south of Bristol; and 9 inches at Houghton.
2005: A significant winter storm visited the region on November 27-29, 2005, producing a wide range of wintry precipitation across the area. Snow and blizzard conditions occurred across central and north central South Dakota, while freezing rain and ice accumulations took front stage in northeast South Dakota and west central Minnesota. Across most of central and north central South Dakota, snow began in the late afternoon and early evening hours of the 27th, with significant snowfall accumulations occurring by the time the snow ended later in the day on the 28th. Snowfall accumulations ranged from as little as two inches to as much as 20 inches. Strong northwest winds of 30 to 50 mph, with gusts to 70 mph, caused widespread blizzard conditions from the early morning until the late afternoon hours of the 28th. Visibilities were reduced to zero many times across the area with snowdrifts of 5 to 10 feet in some places. Some power lines were also brought down in the Pierre and Fort Pierre area due to snow accumulation and high winds. Many roads, including Interstate 90, were closed due to the treacherous travel conditions. Several accidents occurred during the storm, and many motorists were also stranded. Several people had to be rescued. Schools, businesses, government offices, and many other organizations were closed. FEMA, state officials, and the governor surveyed the storm damage. Some of the significant snowfall amounts included 7 inches at Eureka, 8 inches at Onaka, 10 inches at Onida and Fort Thompson, 11 inches near Presho, 16 inches at Highmore, and 21 inches at Kennebec. To the east of this heavy snow and blizzard area, widespread freezing rain began during the morning to early afternoon of the 27th, creating significant ice accumulations of 1 to over 2 inches. The freezing rain changed to snow on the 28th, and northwest winds increased to 30 to 40 mph, gusting to 60 mph. The high winds and heavy ice accumulations caused several thousand power poles (some steel), along with several thousand miles of power lines, to come down, resulting in widespread power outages. The ice and winds also damaged several hundred miles of high-voltage power lines and towers. Some power substations were also shut down by the ice and wind. Thousands of trees were also either damaged or downed due to the heavy ice accumulations and the wind. Many of the fallen trees and branches caused damage to homes and vehicles. The radio station in Milbank went off the air due to its collapsing radio tower. Tens of thousands of people in many communities and rural areas were without power for several days, with some people without power for as long as two weeks. Telephone and cellular phone service was also down for several days. Countless schools, businesses, government offices, and other organizations were closed for several days. FEMA, state officials, and the governor also toured this damaged area, resulting in a presidential disaster declaration. Hundreds of utility workers from South Dakota,
