Population over time
2 figuresDimock grew from 125 to 137 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.

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.
| When | Event | Place named | Harm | What the report says |
|---|---|---|---|---|
| July 2009 | Hail | Dimock | $3,000,000 | Large hail caused widespread damage to vehicles, windows, and siding and roofs on homes. The hail also caused widespread crop damage, with over 66 thousand acres affected. Damage to both property and crops was estimated to be in the millions of dollars. |
| April 2011 | Flood | Dimock | $1,000,000 | Major flooding of the James River, as well as flooding of small streams and lakes in the county, continued through April. Much farmland remained flooded, both near to and away from the James River. The James River was 5.8 feet above flood stage northeast of Scotland on April 1st, and fell very slowly during the month. A large area of land and numerous roads were flooded at the start of the month. Water was running over other roads, from flooded streams, creeks, and fields as well as from the James River. Many roads were heavily damaged. Some homes and businesses were also flooded, with the flooding of these places slowly alleviating through the month. High water and groundwater levels from record precipitation in the year 2010, a main reason the flooding onset was so fast in March, was also a main reason that the flooding subsided so slowly during April. |
| June 2008 | Flash Flood | Dimock | $1,000,000 | Repeated heavy rain from thunderstorms caused widespread flash flooding in western Hutchinson County. Communities affected included Parkston and Tripp, with Parkston being especially hard hit. Numerous roads and homes were flooded, including up to 200 homes in Parkston. Parks and businesses were also flooded. In nearby rural areas, numerous fields were flooded, causing an unknown amount of crop damage. Small streams such as Pony Creek in Parkston flooded, adding to the damage. |
| September 2019 | Flood | Dimock | $25,000 | A continuation of flooding from August, the James River near Mitchell (gage site JRMS2) responded sharply to 5 to 8 inches of rainfall between September 10-12 (7.54 inches at Mitchell) to reach the 4th highest crest on record at 8.05 feet above flood stage on September 13. Innumerable county and township roads near the river were inundated, with significant flooding of South Dakota Highway 37 east of Mitchell and 42 east of Ethan. Significant amounts of agricultural land remained flooded. Moderate flooding continued at the end of the month. |
| August 2013 | Thunderstorm Wind | Dimock | $20,000 | Thunderstorm winds blew in the roof and doors of a hog barn, and damaged siding on buildings. Ventilation fans in the hog barn were damaged, and air control shutters were destroyed. The winds also caused tree damage, including a few trees blown down. The winds were accompanied by large hail. |
| August 2019 | Flood | Dimock | $10,000 | A continuation of flooding from July, the James River near Mitchell (gage site JRMS2) crested 4.97 feet above flood stage on August 8. Many rural roads near the river were inundated, with continued flooding of significant amounts of agricultural land. Moderate flooding continued at the end of the month. |
| August 2013 | Hail | Dimock | $10,000 | Large hail caused crop damage in the area. Both corn and soybean crops were damaged, but the leaf damage to the beans was suspected of making that crop suffer the greater damage. The amount of crop damage was not known, but over one thousand acres on one family farm suffered lost or damaged crops. The hail was driven by damaging winds and also caused damage to vehicles, windows, roofs, and siding. |
| August 2013 | Hail | Dimock | $10,000 | Large hail damaged siding, vehicles, and crops. The hail covered the ground. The amount of crop damage was not known. |
