How Stearns County floods

Flash flooding from summer thunderstorms dominates the flood history of Stearns County. According to NOAA Storm Events data from the last 30 years, flash floods occurred in 18 events, compared to 6 general flood events.

Severe events are documented in the historical record. On June 23, 2022, back-building storms produced excessive rainfall amounts up to 7 inches in central Minnesota before rates diminished. A front on June 6, 2015, brought rainfall rates of 1 to 2 inches per hour across northern Stearns County between Sauk Centre and Sartell. Spring melt conditions also contribute to flooding, as seen during a severe spring flood melt along regional rivers in March 2019 caused by above-average snowpack and subsequent warming.

Property owners should note claim distributions across FEMA flood zones. Zone A recorded 59 claims with an average payout of $17,190 and an average recorded water depth of 5 inches. Zone X recorded 25 claims with an average payout of $7,129 and an average recorded water depth of 24 inches. Zone X_SHADED recorded 12 claims with an average payout of $4,473 and an average recorded water depth of 2 inches. Zone X_UNSHADED recorded 9 claims with an average payout of $4,832 and an average recorded water depth of 3 inches, while the unknown zone recorded 7 claims averaging $16,024 with an average recorded water depth of 1 inch.

From the storm reports

Flash Flood · Jul 23, 2025. Several clusters of storms moved from central South Dakota into Minnesota during the morning, then more widespread coverage of storms developed and persisted throughout much of the day. The main axis of heavy rainfall was tied to a slow moving boundary that started across central Minnesota in the morning and progressed towards southern Minnesota by the late evening.||While many locations saw heavy rainfall amounts…

Flash Flood · Jun 23, 2022. During the late afternoon, and early evening of Thursday, June 23rd, a small complex of storms developed in central Minnesota. These storms were developing along an 850mb confluent boundary with an above normal plume of PWATs of 1.25. Due to a high freezing level, a sounding profile suggesting efficient warm-rain processes dominated. With back-building storms across central Minnesota, rainfall amounts were excess…

Flood · Mar 18, 2019. There were many factors that led to a severe Spring flood melt along the Minnesota and Mississippi Rivers and several of their tributaries during the last two weeks of March. The first factor was above average snowpack, especially over the Minnesota River Valley for mid March. Additionally, the added effect of a cold late Winter kept this snowpack deeper into the early Spring. Once temperatures warmed, and snow be…

Flash Flood · Jun 6, 2015. During the evening of Saturday, June 6th, a front was moving slowly southeast across central and west central Minnesota. A line of showers and thunderstorms was developing along it as it sagged to the east-southeast. Between 9 and 10:30 PM LST, there was one band of very heavy rainfall, with rates of 1-2 inches per hour, that was moving across northern Stearns County. By midnight, almost all of northern Stearns Co…

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Cross-section of a river floodplainDiagram: a river valley.

  1. A / AE Inside the 1%-a-year floodplain: about a 26% chance of flooding over a 30-year mortgage. AE has a mapped base flood elevation; plain A does not.
  2. Floodway The channel and the land beside it that has to be kept clear enough to carry the flood. Building here is tightly limited.

Flood insurance in Stearns County

If a building in Stearns County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
