MRGO behaving oddly

Site of the Dam across Bayou la Loutre

MRGO, constructed in 1965 as a short cut from the Gulf of Mexico to the Port of New Orleans,  has been officially closed for several weeks now. It will remain a factor in the landscape for a long time, until a second closure is made at Bayou Bienville, close to New Orleans, and until the cypress forests and fresh and brackish marshes the canal destroyed are restored. A very tall order.

In the meantime anglers are finding good catches for speckled trout, white trout, red fish, and drum on the inland side of the dam. The fish are grazing for the small critters that attach themselves to the instant reef the dam became.

Fishing on the gulf side of the dam, however, is not so good. It’s a dead zone, oxygen-deprived water 40 feet deep, which fish that can swim avoid, and in which fish that can’t die.

And another thing, the dam seems to have disrupted the way the tides flow though the marshes.
