Deep River isn’t graded for hazard risk: Deep River has 147 residents; we grade towns of 1,000 or more.
What Deep River faces
Each hazard’s share of the building damage FEMA expects here, and how its rate compares with the rest of the country.
River and rain flooding
Coastal flooding
Earthquakes
Shares are of FEMA’s expected building damage, the measure the grade uses; ranks compare each hazard’s building-damage rate with all 85,154 U.S. census tracts. In FEMA’s terms, river and rain flooding is FEMA’s “Inland Flooding” (rivers and streams overflowing their banks, or rain overwhelming drainage). FEMA defines coastal flooding as high or rising tides and storm surge, so surge damage is counted there. Drought isn’t listed: FEMA counts its losses in crops only.
Does Deep River flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Deep River. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Deep River isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
Insurance rates: Wahkiakum County.The storms Deep River remembers
None of the 28 disasters declared for Wahkiakum County shows FEMA aid or repair money reaching Deep River itself in FEMA’s records, so these are its biggest flood-claim years.
Wahkiakum County has had 28 natural disasters declared by the President since 1953, most often severe storms, then floods. Not counted: the 2005 Hurricane Katrina evacuee emergency, which covered counties that took in evacuees.

| Grays River | — | 195 residents; we grade 1,000+ | |
Hazard risk = FEMA’s expected yearly building damage per dollar of building value, vs. the 21,298 U.S. towns we grade; the map is shaded by fifths of the same scale. Flood claims = paid federal flood insurance claims on record.
