In flood insurance claims here that reported a flood depth, the average was 3 inches.

From the storm reports

Flash Flood · Jul 12, 2018. A line of thunderstorms that developed in northern Minnesota, sagged southward into central Minnesota during the morning of Thursday, July 12th. High rainfall rates, and training of the storms, caused up to five inches of rain (based on radar) in less than three hours in northern Kanabec County. This amount of rainfall produced flash flooding, and local officials indicated damage to many county roads throughout th…

Flash Flood · Jul 6, 2017. A small complex of severe storms drifted southward across northern Kanabec County and produced a swath of large hail, torrential rainfall and flooding. The hail lasted nearly an hour in some spots, with damaging hail generally from the Knife Lake area northeast to the Pomroy Lake area. Flooding was also reported, with damage to area roads.

Flash Flood · Jul 11, 2016. The morning of Monday, July 11th, two waves of thunderstorms moved across west central and central Minnesota. Very heavy rainfall and isolated hail occurred with the main area of storms. But these storms also produced a wide area of one half to two inches of rain by sunrise. ||The morning two events set the stage for flooding in central Minnesota as several additional waves of thunderstorms developed during the af…

Flood · Apr 1, 2001. Heavy snowfall during winter remained on the ground through the end of March and then rapidly melted, resulting in river stages close to record levels. Water began to gush through drainage ditches, streams and into the mainstem rivers during midday April 1. Heavy rain April 7-8 over much of central Minnesota (see corresponding flood entry) prolonged the high water and also added one or two feet to many crests dur…

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 Kanabec County

If a building in Kanabec 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.
