Flash flooding from summer thunderstorms and snowmelt-driven river flooding dominate the flood profile of Hyde County, South Dakota. Over the last 30 years, the NOAA Storm Events Database has recorded 12 flood events and 10 flash flood events.
Recent history illustrates these seasonal risks. In August 2024, widespread slow-moving thunderstorms produced heavy rainfall with emergency management and trained spotters estimating about 3.5 inches of rain. Earlier, in April 2023, unusually cold late spring conditions and a deep snowpack ranging from 15 to 30 plus inches contributed to flooding as conditions warmed. Widespread flooding also occurred in March and April 2019 due to above-normal winter snowfall, ice jams, heavy rains, and subsequent snowmelt that damaged roads, culverts, and bridges while flooding fields and structures.
Federal records indicate limited historical participation in the National Flood Insurance Program within Hyde County, showing a single claim categorized under Zone UNKNOWN with an average payout of $0 and an average recorded water depth of 0 inches. Properties situated near rivers, creeks, low-lying fields, and unmapped or unknown flood zones should pay the closest attention to these recurring snowmelt and heavy rainfall hazards.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Hyde 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.
