Spanish Lake

A placid sheet of water sits sixteen feet higher than the bayou below it — a ghost of the Mississippi River, stranded when the river abandoned this channel somewhere between 3,800 and 5,500 years ago. Spanish Lake is an oxbow, left behind when the river cut a straighter path and sealed off the bend. The archaeological record around its banks runs deep; people lived here long before Europeans arrived, drawn by the same combination of high ground and water that would later matter to sugarcane planters. In the early 1800s, a plantation owner saw what the elevation difference made possible. He cut a canal from the lake down to Bayou Teche and used the sixteen-foot drop to turn a grinding mill. It was one of the only known attempts to power sugar production with water in southern Louisiana — a landscape too flat for most mills to work. The canal is documented; whether it succeeded for long is not. The lake sits just south of St. Martinville, accessible by road. You go to see what remains when a river changes its mind: a lake that remembers being part of something larger, and the narrow cut someone dug to make it useful one more time.
