Demonstration Site

The demonstration of stream restoration is in the Geronimo Creek watershed in Seguin, Texas at the Irma Lewis Seguin Outdoor Learning Center.

TWRI is coordinating with partners including the Irma Lewis Seguin Outdoor Learning Center, the Guadalupe-Blanco River Authority and the Geronimo and Alligator Creeks Watershed Partnership on this demonstration.

Riparian restoration and stream bank stabilization will lead to improvements in water quality, in-stream habitat, terrestrial wildlife, aquatic species and overall stream health. In addition, reduced sedimentation rates are a cost-effective strategy for extending the operational life of the state’s water supply reservoirs for water availability. The Geronimo and Alligator Creek Watershed Protection Plan, as does most watershed plans, includes implementing riparian forest and herbaceous buffers to reduce pollutant loads in the watershed.

At the demonstration site, we are implementing riparian buffers using natural bank stabilization techniques and planting native vegetation on one of the two sites of approximately 100 feet to demonstrate the difference in bank erosion rates and sediment suspended in the creek’s water. The vegetation holds the soil particles and stabilizes the bank, reducing bank erosion. The vegetation also acts as a filter for the water, especially during flood events, which, in turn, increases the stream’s overall water quality.

At the conclusion of the project, we will compare the results of erosion and total suspended solids in the creek of the restored site to the upstream non-restored site to show the benefits of the increased vegetation cover on the banks.

    The Texas Water Resources Institute has published its latest Annual Report, focusing on accomplishments and project highlights from 2019.

    The Texas Water Resources Institute’s Urban Riparian and Stream Restoration Program will host an Urban Stream Processes and Restoration Training from 8:30 a.m.-4 p.m. Oct. 29 in New Braunfels for professionals interested in conducting stream restoration projects around the Interstate 35 corridor.

    If you follow Texas Water Resources Institute on social media (@TxWRI), you may have noticed our monthly program spotlights, but in case you missed it, for the month of September the focus was on our Urban Riparian & Stream Restoration Program.

    This month’s txH2O highlight is from the Fall 2017 issue of the magazine and focuses on the effectiveness of low impact development (LID) practices in reducing negative environmental impacts of urban growth.

    The Urban Riparian and Stream Restoration Program of the Texas Water Resources Institute will host an Urban Stream Processes and Restoration training from 8:30 a.m.-4 p.m. Sept. 19 in McKinney for professionals interested in conducting stream restoration projects in and around the Dallas area.

    From a math major to a watershed saver, Clare Entwistle, Texas Water Resources Institute (TWRI) research associate, knows that protecting riparian areas is important for the future of Texas.

    Riparian and natural resource professionals discussed current innovations and issues in riparian restoration and management at the Urban Riparian Symposium: Balancing the Challenges of Healthy Urban Streams Feb. 15-17 in Houston at Rice University’s BioScience Research Collaborative Building.

    The Urban Riparian Symposium will be held Feb. 15-17, 2017, in Houston, and natural resource professionals are invited to attend, share ideas and discuss management and policy issues.

    Even in cities, amidst the tall buildings, fast cars and busy people, there are still natural resources that need protection — particularly urban riparian areas, according to Nikki Dictson, Texas Water Resources Institute Extension program specialist. These vegetative buffers found along rivers and streams are complex ecosystems that include the land, plants, animals and network of streams within them.
