Sustainable Rivers

Big Cypress Bayou/Caddo Lake, TX & LA - Enhancing connected rivers, lakes, and wetlands

In eastern Texas the Big Cypress Bayou flows into Caddo Lake, which was named a Wetland of International Importance by the Ramsar Convention. Sustainable Rivers Program activities are seeking to re-introduce seasonally timed variability in river flows to regenerate rare cypress forests, support bottomland hardwoods, and improve fish habitats.

Reduced flow variability has also allowed invasive species to impact much of the native ecosystems. Collaborating with many partners, the Corps and Conservancy are aiming to use periodic high flow conditions and dry spells to invigorate floodplain and backwater habitats.

The Big Cypress/Caddo Sustainable Rivers project involves Caddo Lake, located in Northeast Texas, and its contributing tributaries and associated wetlands. The watershed is approximately 2,970 square miles, about a third of which is regulated by Lake o’ the Pines and other upstream reservoirs.

Story

The Caddo/Cypress Sustainable Rivers project is focused around Caddo Lake, located in North East Texas on the Texas Louisiana border, its contributing tributaries, and associated wetlands. The watershed is approximately 2,970 square miles, about a third of which is regulated by Lake o’ the Pines and other upstream reservoirs. Lake o' the Pines is a U.S. Army Corps of Engineer reservoir with the dam and associated infrastructure, as well as all the lake project lands, being federally-owned and administrated by the Fort Worth District, for the primary purpose of flood control and secondary purposes of water supply, recreation, and fish and wildlife conservation.   Read More
