Pistol River, OR Coastal Erosion Rate

Is the coast eroding 1.5 miles south of Pistol River, OR?

No significant trend

The coast 1.5 miles south of Pistol River, OR shows no statistically significant trend either way. USGS's transects measured a rate here, but it's smaller than the survey's own margin of error for this stretch, so calling it "eroding" or "growing" would overstate what the data actually shows.

What "Pistol River" means on this page

Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Pistol River, OR into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 42.27°N, 124.40°W. The survey behind it runs to 2002-2011, in USGS's Pacific Northwest assessment, using the LRR method. Shoreline surveys aren't repeated every year, so this is the most recent long-term measurement USGS has published for this coast, not a live reading.

Where this fits nationally

This reading comes from 40 individual transects averaged together, 43% of which measured erosion rather than growth. The published margin on this reading runs ±1.81 ft/yr. Taken at face value, this segment's raw 0.11 ft/yr reading would land it 860 of 1211 nationally - a number worth ignoring, since it's statistical noise rather than a real trend. Source: USGS Open-File Report 2012-1008. Rank 1202 nationally for growth belongs to Long Beach, WA, 286 miles from this stretch, measured at 5.37 ft/yr. 1.6 miles away, Pistol River, OR is the nearest other measured stretch: also no significant trend.

Not this whole stretch, just Pistol River itself: the Coastal Change Hazards Portal is USGS's own live version of this data.
