Lincoln Beach, OR Coastal Erosion Rate

Shoreline change 1.2 miles southwest of Lincoln Beach, OR

No significant trend

The coast 1.2 miles southwest of Lincoln Beach, 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 this reading actually covers

Nothing here is parcel-level. USGS's raw transects run every few hundred feet along the shore; this page averages the ones nearest Lincoln Beach, OR into one ~3.5-mile reading rather than picking a single arbitrary line to represent the area. Centered near 44.86°N, 124.04°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.

What backs this reading up

This reading comes from 80 individual transects averaged together, 26% of which measured erosion rather than growth. USGS's confidence interval here is ±2.42 ft/yr. Taken at face value, this segment's raw 0.22 ft/yr reading would land it 935 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 1210 nationally for growth belongs to Chincoteague, VA, 2530 miles from this stretch, measured at 11.04 ft/yr. 2.5 miles up the coast, Lincoln Beach, OR shows the same lack of a significant trend.

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