How Pend Oreille County floods

Riverine and general flooding dominates Pend Oreille County, accounting for 13 recorded events compared to 5 flash flood events over the last 30 years. Spring weather frequently triggers these conditions, as demonstrated in May 2018 when accelerated snowmelt in the Pend Oreille and Clark Fork River basins caused the Pend Oreille River to reach moderate flood levels from mid-May through early June, resulting in inundated yards, recreation sites, and first-floor home flooding between Newport and Jared. Earlier in April 2018, persistent wet weather delivered 1.79 inches of rain to Boundary Dam and 1.6 inches to Newport, saturating the ground and leading to areal floods and debris flows in mountainous areas.

National Flood Insurance Program records show claims across multiple zones, with Zone A averaging 40 claims with an average payout of $16,951 and an average recorded water depth of 7 inches. Zone X (unshaded) recorded 38 claims averaging $18,679 with an average water depth of 7 inches, while Zone X recorded 20 claims averaging $16,956 with an average water depth of 2 inches, and Zone D recorded 1 claim averaging $20,377 with 0 inches average water depth. Property owners near rivers and those located in Zone A and unshaded Zone X should pay the closest attention to flood risks.

Newport measured 1.6 inches during the same period and Mazama measured 1.01 inches. Holden Village recording 1.48 inches. All of this rain lead to saturated ground conditions by the beginning of the third week of April and set the stage for a rash of areal flo…

Flood · May 11, 2018. An above average snow pack in the mountains drained by the Pend Oreille and Clark Fork River basins melted at an accelerated rate during the month of May. Run off from this snow melt caused the Pend Oreille River to achieve moderate flood level for an extended period of time from the middle of May through the first week of June. ||Numerous homes along the river particularly between the towns of Newport and Jared s…

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.

Flood insurance in Pend Oreille County

If a building in Pend Oreille 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.
