How Otero County floods

Flash flooding from summer thunderstorms and river overflow dominate the flood character of Otero County, supported by 27 flash flood events and 12 general flood events over the last 30 years, including one recorded death.

Recent occurrences illustrate these risks. In June 2024, snowmelt runoff in the upper Arkansas and high flow releases from Pueblo Reservoir caused minor flooding at numerous forecast points along the Arkansas River. Shortly after, in July 2024, locally heavy rainfall produced a quick rise and a brief period of minor flooding along the Arkansas River in La Junta.

Property owners should review their flood risk according to FEMA zone classifications. The highest volume of National Flood Insurance Program claims occurs in Zone A, which accounts for 130 claims with an average payout of $14,437 and an average recorded water depth of 14 inches. Additional claims are distributed across Zone X_SHADED (3 claims, averaging $46,286 and 4 inches of water), Zone X (1 claim, averaging $66,400 with 0 inches of water), Zone X_UNSHADED (1 claim, averaging $10,553 and 1 inch of water), and Zone UNKNOWN (4 claims with $0 average payout and 0 inches of water). Homeowners, real estate agents, and journalists should pay the closest attention to properties located within Zone A and along the Arkansas River.

From the storm reports

Flood · Jun 12, 2024. Snowmelt runoff in the upper Arkansas (above Pueblo) and high flow releases from Pueblo Reservoir resulted in minor flooding at numerous forecast points along the Arkansas River.

Flash Flood · Jul 7, 2024. Strong storms and flash flooding on July 7th for Prowers, Bent, Otero Counties.

Flood · Jul 3, 2024. Locally heavy rainfall resulted in a quick rise and brief period of minor flooding along the Arkansas River in La Junta.

Flash Flood · Jul 19, 2023. An upper level high pressure center was located over central Arizona and central New Mexico which resulted in a favorable pattern for efficient diurnal wind fluctuations including upslope oriented winds towards WFO Pueblo's eastern mountains. Weak waves embedded in the upper level northwesterly flow enhanced the lift and the pattern enhanced the deep shear. The result was a very rare mountainous tornado that was o…

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.

Flood insurance in Otero County

If a building in Otero 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.
