Bayou Teche

About

Bayou Teche 1764 — Acadian Settlements of the Attakapas. The Teche's water tells a steady story. USGS gauge 07385700 records an average of 479 cubic feet per second, and the Bayou Teche Paddle Trail runs best when the channel sits between 250 and 725 CFS — a Class II passage across St. Landry, St. Martin, Iberia, and St. Mary parishes. At 135 miles, it is a long, deliberate corridor rather than a whitewater run, and its character is inseparable from the forested wetland it drains.

Before any of the settlement history, the bayou flowed through the ancestral territory of Indigenous peoples. It served as a primary travel corridor, hunting ground, and gathering place. The Attakapas and Opelousas nations used the Teche as their principal route of trade with the French in New Orleans, and La Salle had explored the channel in 1682 during his descent of the Mississippi. The nineteenth-century cession framework — 1800s-era treaties, the 1830 Indian Removal Act, and the 1840s-1890s allotment era — reshaped who held the land along its banks.

European settlement arrived with the Acadians in 1764. The first Acadian community in Louisiana, Cabahannocer, was founded that year on Bayou Lafourche, but within a year the exiles had moved west up the Teche to establish St. Martinville — the cultural capital of Cajun Louisiana and the setting Henry Wadsworth Longfellow drew on for 'Evangeline' in 1847. This layered arrival of peoples and industries is now gathered at the Bayou Teche Museum in New Iberia, and its environmental and cultural arc is traced in depth by Dr. Shane K. Bernard in his book 'Teche: A History of Louisiana's Most Famous Bayou.'

The watershed carried the weight of industry through the nineteenth and early twentieth centuries. It was logged from the 1830s through the 1920s to feed the 1850-1910s regional timber industry and the 1860-1910s railroad expansion, worked by local sawmills, logging drives, and downstream lumber operations. The 1910 exhaustion of the old-growth stands, the 1915 start of state forestry conservation, and the 1930s establishment of state forests brought large-scale logging to an end. Hydrological study followed the industry: the 1870s-1890s USGS surveys, the 1880s-1910s establishment of gauging stations, and the 1910s-1930s state geological streamflow assessments were the first comprehensive measurements of the Teche, later joined by 1950s-1970s pollution control studies and Clean Water Act assessments from 1972 to 2000.

The modern Teche is a river under repair. Since 2010, the Louisiana Department of Natural Resources, working with local watershed partnerships, has addressed more than a century of logging, agricultural, and industrial impacts through streambank stabilization from 2015 to 2024, native fish restocking from 2017 to 2024, a nutrient reduction strategy begun in 2018, and water-quality improvements from 2020 to 2024. The channel endures as both heritage and habitat, anchored by the Bayou Teche National Wildlife Refuge, established in 2001 to protect 9,028 acres of forested wetland. Recognized as a National Historic Waterway and a designated water trail, the Teche today carries paddlers along the same banks the Acadians first settled more than 250 years ago.
