How Clark County floods

Clark County experiences a flood risk profile dominated by regular river floods and flash floods, supported by historical records showing 72 flood events and 65 flash flood events over the last 30 years, alongside occasional tropical systems.

Recent occurrences illustrate these impacts. In January 2025, heavy rainfall caused both the Ouachita River at Arkadelphia and the Little Missouri River at Boughton to enter minor flood stages. A subsequent multiday severe weather event in April 2025 brought widespread flash flooding and river flooding across the state, with total rainfall amounts reaching between half a foot and over one foot in many locations and keeping points along the Ouachita River in flood through the end of the month.

Property owners and real estate professionals should pay the most attention to locations within high-risk Special Flood Hazard Areas designated as Zone A. FEMA records show Zone A accounts for the vast majority of local claims with 25 filed, resulting in an average payout of $44,608 and an average recorded water depth of 2 inches. While fewer claims originate from moderate-to-low risk zones such as Zone X_UNSHADED, residents across all designated zones should evaluate their specific property risk.

The zones you’ll see on the map

Flood insurance in Clark County

If a building in Clark 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.
