How Ouachita County floods

Standard river flooding and general flooding dominate the historical record in Ouachita County, accompanied by frequent flash floods and occasional tropical systems. Over the last 30 years, NOAA recorded 105 flood events, 32 flash flood events, 6 tropical storm events, and 2 tropical depression events. Recent multi-day heavy rainfall events led to significant river overflows, such as the Ouachita River remaining in minor flood stage through January 2025, and similar widespread flooding along the Ouachita and other regional rivers in February 2025 and April 2025.

National Flood Insurance Program records show claims across multiple zones, indicating risk extends beyond designated high-risk areas. Zone A accounts for the majority of claims with 65 filings, an average payout of $19,771, and an average recorded water depth of 5 inches. Properties in Zone X recorded 17 claims with an average payout of $18,613 and an average water depth of 7 inches. Unshaded Zone X recorded 6 claims averaging $21,340 with an average water depth of 11 inches, while shaded Zone X recorded 3 claims averaging $42,173 with an average water depth of 6 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located near the Ouachita River and other waterways, as well as properties situated in both Zone A and the various Zone X designations where historical claims and standing water depths have been documented.

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. The floodway is the channel and the land beside it; the 1%-annual-chance flood surface (the base flood elevation) covers the valley floor as zone A or AE; a narrow band higher up is shaded X, the 0.2% floodplain; higher ground is X.0.2% CHANCE A YEAR (500-YEAR)BASE FLOOD ELEVATION · 1% A YEARXAEFloodwayAEX
  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.
  3. X shaded The 0.2% (500-year) floodplain, plus some levee-protected and very shallow flood areas.

Flood insurance in Ouachita County

If a building in Ouachita 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.
