Lamar, TX Coastal Erosion Rate

What USGS measures 15.8 miles east of Lamar, TX

No significant trend

Nothing alarming measured 15.8 miles east of Lamar, TX: whatever shift USGS's transects picked up here is too small to call reliably one way or the other, which this site reports as "no significant trend" rather than forcing a direction.

What this reading actually covers

Lamar, TX is the nearest named place, 15.8 miles away, to a ~3.5-mile stretch of coast USGS has surveyed - the reading below covers that whole stretch, not a single property in it. Segment center: 28.18, -96.73. Survey years: 2001, method LRR, from USGS's Gulf of Mexico shoreline-change assessment. That's how current the data is here, real, but not a live feed, since a shoreline survey is a major undertaking, not an annual check-in.

How solid is this number

Averaging 38 separate transects produced this segment's rate, with 0% individually reading as erosion, rather than relying on any single survey line. USGS's confidence interval here is ±1.56 ft/yr. The unadjusted figure here, 0.65 ft/yr, would place it 1055 of 1211 if ranked directly - but an unreliable rank isn't a useful one, which is exactly why "no significant trend" is the headline instead. Source: USGS Open-File Report 2004-1089. Rank 969 nationally for growth belongs to Portsmouth, NH, 1773 miles from this stretch, measured at 0.32 ft/yr. Lamar, TX, 1.9 miles off, is the adjacent measured stretch, itself no significant trend.
