Louisiana coastline gaining land since 2008, new report says

Buttressed by a seven-year respite from major hurricanes, Louisiana’s fragile coast has added an average of more than two football fields of land per hour since 2008, according to the first official government analysis of coastal land loss since 2011.
quote:
From late 2008 to early 2016, the USGS measured a net gain of almost 230 square miles across the whole Louisiana coast, meaning the state actually added a little more than 2 football fields an hour over that relatively short timeframe.
But USGS geographer Brady Couvillion warns in the report released Wednesday that the measurements are still within the margin-of-error and may not be indicative of any long-term trend. The improvements barely make a dent in the state’s disturbing trend of land loss over the last 85 years.
Louisiana has lost a net area of almost 1,800 square miles since measurements began in 1932 – an area one-and-a-half times the size of Rhode Island.

Good read, I had read about the wax lake area gaining land before, but was surprised to read about the atchafalaya basin, must be the duck hunters....sarcasm off.
quote:
Six of the state’s nine coastal basins gained land area since the last report. The three that still suffered a net loss were the Mermentau Basin in southwest Louisiana, the Mississippi River Delta Basin in Plaquemines Parish and, notably, the Atchafalaya Basin in coastal Acadiana, which had been the lone bright spot during the decades of persistent land loss.
The Atchafalaya River, largely unfettered by levees and floodwalls that have hindered sediment distribution along the Mississippi River, has helped that region build more land than it’s lost since 1932. But the Atchafalaya Basin suddenly shrunk in observed size after hitting a peak at the end of 2013, according to the latest USGS data.

It's sad to see what has happened in Venice area over the last 20 years or so.
