How Gogebic County floods

River flooding and flash flooding from heavy rain and snowmelt dominate the flood history of Gogebic County. Over the last 30 years, NOAA recorded 9 flood events, 6 flash flood events, and 2 lakeshore flood events.

Recent historic impacts are documented in NOAA storm narratives. In April 2019, abundant snowpack combined with periods of moderate to heavy rain to cause widespread minor river flooding. Later, rapid melting of above-normal snowpack caused extensive flooding in April 2023, prompting a state of emergency declaration from Governor Whitmer for eight counties in west and central Upper Michigan.

NFIP insurance claims data indicates that homeowners and real estate agents in both high-risk and moderate-to-low risk zones should pay attention to flood preparation. Zone X recorded 8 claims with an average payout of $7,086 and an average recorded water depth of 2 inches. Zone A recorded 1 claim with an average payout of $10,000 and an average recorded water depth of 0 inches, while Zone X_UNSHADED recorded 1 claim with a $0 average payout and an average recorded water depth of 0 inches.

From the storm reports

Flood · Apr 12, 2023. Rapid melting of much above normal snowpack caused widespread, and at times, extensive flooding over portions of west and central Upper Michigan from the 12th into the 25th. Extensive impacts from the flooding caused Governor Whitmer to declare a state of emergency declaration for eight counties in west and central Upper Michigan on the 21st.

Flash Flood · Aug 9, 2020. Increasing moisture and instability ahead of cold front approaching from the Northern Plains aided the development of strong to severe thunderstorms over portions of western Upper Michigan from the afternoon of the 9th into the morning of the 10th.

Flood · Apr 22, 2019. Abundant and anomalously wet snow pack along with periods of moderate to heavy rain contributed to widespread minor river flooding across much of west and central Upper Michigan from the 18th through the end of the month.

Flash Flood · Jun 17, 2018. A very moist and unstable air mass in place and the presence of a nearly stationary frontal boundary produced several rounds of severe storms and flash flooding across portions of west and central Upper Michigan from the 16th into the 17th. The hardest-hit area was in Houghton County where widespread rain amounts of 3 to almost 7 inches caused massive flood damage to the City of Houghton and surrounding areas an…

Flood insurance in Gogebic County

If a building in Gogebic 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.
