How Lake of the Woods County floods

Flash flooding from summer thunderstorms and spring snowmelt dominates the flood character of Lake of the Woods County, with NOAA records detailing 11 flash flood events and 5 general flood events over the last 30 years. Notable historical impacts include a severe June 2002 event where heavy rainfall brought widespread flooding, with the Baudette ASOS reporting 7.64 inches of rain and Norris Camp recording 11.95 inches over a two-day period. Spring warming cycles also drive local flood risks, such as the March 2009 snowmelt event caused by consecutive periods of high temperatures in the 40s and low 50s, and the March 2004 flooding that resulted in rushing water washing out County Road 69 west of Pitt.

FEMA National Flood Insurance Program records indicate historical claims have been filed in both moderate-to-low risk and high-risk areas. Properties located in Zone X recorded 3 claims with an average payout of $46,885 and an average recorded water depth of 4 inches. Properties located in Zone A recorded 2 claims with an average payout of $17,424 and an average recorded water depth of 2 inches. Homeowners, real estate agents, and journalists monitoring properties in both designated special flood hazard areas and standard risk zones should pay close attention to these historical payout and water depth patterns.

From the storm reports

Flood · Mar 25, 2009. A stretch of warmer weather occurred from March 14th to 17th, which resulted in high temperatures in the 40s and low 50s. The snow depth in Fargo on the 14th was 15 inches with a melted water equivalent of 3.10 inches. By the 17th, the snow depth in Fargo had dropped to 6 inches. This was followed by a couple of cooler days, which temporarily slowed down any additional snowmelt. A second period of warmer weather b…

Flood insurance in Lake of the Woods County

If a building in Lake of the Woods 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.
