June 21, 1983:
An F3 tornado touched down at a resort area two miles west of Pollock. Eleven people fled the southwestern most cabin and crawled under a nearby cabin. The southwest cabin was completely destroyed and the cabin the group crawled under was moved five feet from its concrete block foundation. Four people were treated for injuries. A van, boat and trailer were demolished and a small car was heavily damaged. The tornado turned east and reformed four miles east of Pollock, where it touched down briefly and dissipated. Another F3 tornado touched down in open prairie three miles northeast of Glad Valley and moved northeast, creating a path of destruction as it progressed. On one farm, nine buildings were wiped out and scattered up to two miles away. Trees and poles were uprooted and scattered a half mile away. This tornado was estimated to be on the ground for six miles with a path width of 300 yards. A third tornado, rated F2, touched down seven miles south of Pollock. This tornado damaged several cabin roofs, a restaurant, and downed several trees. Boats were tossed in a lake and picnic tables were hurdles against cars.

Numerous slow moving thunderstorms produced very heavy rains across north-central South Dakota from early morning to the early evening hours of the 21st, and again from early morning to the early afternoon hours on the 22nd. The two day rainfall amounts ranged from two to nearly seven inches across north-central South Dakota. Some rainfall amounts included; 2.12 inches at Gettysburg; 2.20 at Hoven; 3.33 at Roscoe and Eureka; 3.50 at 2.5W Bowdle; 3.60 at Trail City; 3.77 at Herreid; 4.00 at Firesteel; 4.45 at Bowdle; 4.50 at 20NW of Gettysburg; 5.06 at 9NE Timber Lake; 5.45 at Timber Lake; and 6.80 at 7NW Trail City. Many roads were flooded and closed. In the Timber Lake, Firesteel, and Isabel area, flooding washed gravel off the roads in 40 to 50 places. Some crops were also flooded. A bridge was washed out on the Dodge draw road just off U.S. Highway 83.
June 21, 2013:
A long-lived severe thunderstorm developed over the southern Black Hills and moved eastward across the South Dakota plains during the morning hours. The storm produced very large hail to softball size from eastern Custer to northern Jackson Counties. The softball size fell 12 miles east-southeast of Fairburn in Custer County, damaging property. This storm intensified along a strong warm front with very unstable air and strong deep layer winds into several supercell thunderstorms and a damaging line of thunderstorms/bow echo across parts of central and northeast South Dakota through the afternoon hours. Damaging winds up to 90 mph uprooted large trees and caused considerable structural and crop damage and loss of power to those along the path. The worst wind damage was located at Lake Poinsett, Watertown, and Milbank. A woman was killed and her husband was seriously injured on Lake Poinsett when their lake house was destroyed. Numerous trees were downed along with many structures damaged or destroyed. Many trees had fallen onto homes, cabins, and trailers. The bowling alley in Clear Lake lost its roof along with numerous pole barns being destroyed along the path of the storm. Thousands of people were also left without power. Four tornado touchdowns occurred along with hail up to the size of softballs. Isolated flash flooding also occurred. Codington, Hamlin, Grant, and Deuel counties were all declared in a Federal Disaster Declaration. Total damage estimates were around 1,100,000 dollars.
