From the storm reports

Flash Flood · Jun 29, 2025. A couple rounds of scattered heavy rains from late on the 28th through the morning of the 29th brought 1 to 2 inches of rainfall, to several areas from Bloomington into parts of Brown County and Lawrence County. Soon after, more impressive rainfall rates occurred over the same areas from the 29th evening into very early on the 30th, where an additional 3 to 6 inches of rainfall fell on a few local areas.||Resulta…

Flash Flood · Apr 4, 2025. The final round of rain in a stretch of 4 days brought rain amounts of 2-4.5 inches of rain to central Indiana in addition to the 3-5 inches that had fallen. This led to additional widespread flash flooding and exacerbated ongoing creek and river flooding to a point that many main stem rivers ended up reaching major flood stage.

Flash Flood · Jun 19, 2021. A long lasting and multi faceted storm system moved through central Indiana beginning during the late afternoon hours of June 18th and continued through the evening hours with widespread damaging winds and very large hail before transitioning into a flash flooding event during the overnight hours with significant flash flooding occurring across portions of Owen and Monroe counties. Unfortunately, one person lost…

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.

  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 Monroe County

If a building in Monroe 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.
