The City of Austin Watershed Protection Department has identified the Tannehill Branch Creek Watershed as a priority for water quality improvements such as removal of pollution, improving stream flow and creating a natural habitat along the creek.

Project Overview

The plans call for the following improvements:

  • Modify the existing flood detention pond at Bartholomew Park to include a permanent wet pond
  • Improve the existing wet pond and construct a second wet pond at Morris Williams Golf Course
  • Create a constructed wetland at Morris Williams Golf Course
  • Enhance natural habitat along Tannehill Branch Creek
  • Support existing recreational uses within parkland along Tannehill Branch Creek


Our capital improvement projects take many years from start to finish. The process typically includes the following phases:

  • Preliminary Engineering – when a solution is identified and costs are estimated.
  • Design – when the details are worked out and construction plans drawn up.
  • Bidding and Permitting – when a contractor is hired and all permits are acquired.
  • Construction – when the project is built.

Permitting was completed in 2021, design is estimated to be completed in 2023 and construction is estimated to begin in 2024-2025.
