How Becker County floods

Flash flooding and standard flooding from summer thunderstorms and low pressure systems dominate the flood history of Becker County, MN, accounting for 16 flash flood events and 12 flood events over the last 30 years according to the NOAA Storm Events Database.

Recorded events include a May 2012 storm system that dropped two to six inches of rain, causing water to flow over fields, roads, and town streets, as well as thunderstorms on May 11, 2022, that produced localized street flooding.

NFIP claim data shows that properties in Zone X and Zone X_UNSHADED have experienced the highest volume of insurance claims, with 51 claims averaging an interior water depth of 3 inches and $12,519 in payouts for Zone X, and 39 claims averaging an interior water depth of 6 inches and $20,521 in payouts for Zone X_UNSHADED. Zone A recorded 1 claim with an average water depth of 4 inches and a $20,000 payout, while Zone UNKNOWN recorded 1 claim with an average water depth of 0 inches and a $12,748 payout. Homeowners and real estate agents with properties located in Zone X and Zone X_UNSHADED should pay the most attention to flood risk, as these zones account for the vast majority of historical claims in the county.

From the storm reports

Flash Flood · May 11, 2022. A pre-frontal trough brought thunderstorms into the area during the evening of May 11. Isolated severe thunderstorms brought hail up to 1.5 inches and wind gusts of 58 mph, along with localized street flooding.

Flash Flood · Jul 11, 2016. By the early evening of July 11th, surface low pressure was located over northeast South Dakota, with a warm front extending out to the east into Minnesota. Slow moving thunderstorms formed north of the warm front and dropped large amounts of rain. Other thunderstorms formed later, along a line from Jamestown to Devils Lake to Rock Lake. One storm along this line produced strong winds from Langdon to Walhalla, in…

Flood · May 27, 2012. In the early morning hours of the 27th, an 850mb warm front was draped west to east across southeast North Dakota and west central Minnesota. A strong low level jet kept redeveloping bands of strong thunderstorms, which dropped heavy amounts of rain from Moorhead to Perham to Wadena. A wide swath of two to six inches of rain fell along this line, which resulted in water flowing over fields and roads as well as str…

Flash Flood · Jul 19, 2011. Another night in the long duration heat wave brought another round of nocturnal convection. Early in the morning of the 19th, a weak surface boundary set up across northern South Dakota into west central Minnesota. As the low level jet and warm advection increased after midnight, thunderstorms began to fire. The air mass was extremely unstable with precipitable water values over two inches. The thunderstorms moved…

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.

Flood insurance in Becker County

If a building in Becker 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.
