Cooperation between groups and individuals has been paramount to the success of the Double Bayou Watershed Protection Plan development process. Every person and group has played an important role in the process. The Double Bayou Watershed Partnership (Partnership) expresses thanks to members of the stakeholder workgroups, who committed great amounts of time and energy to participate in the Double Bayou Watershed Protection Plan development. The members of the Agriculture, Feral Hogs and Wildlife Workgroup, the Recreation and Hunting Workgroup and Wastewater and Septic Workgroup supported and directed the process; without them, development of this plan would not have been possible. The Partnership also wishes to thank the stakeholder members of the Geographic Task Force, who spent extra time on aiding with the efforts of on-the-ground fact checking for spatial analysis.

Funding provided through these agencies allowed for development of Double Bayou Watershed Protection Plan and established a solid foundation for watershed stewardship in the Double Bayou Watershed. iii Statement of Purpose A healthy Double Bayou is vital to support regional commerce, while providing native riparian habitat and recreation opportunities in Chambers County. The land surrounding the West and East Forks of Double Bayou provide excellent grazing and farming. In 2012, the West Fork of Double Bayou was listed by the State of Texas for elevated levels of bacteria and low dissolved oxygen. The East Fork of Double Bayou was identified as a concern for near-nonattainment of water quality standards for elevated levels of bacteria and as a water quality concern based on screening levels for low dissolved oxygen. In response, the Double Bayou Watershed Protection Plan was developed using a stakeholder process driven by public participation to provide a foundation for restoring and maintaining water quality in the Double Bayou Watershed. Development of the Plan involved assessing key water quality issues in the Double Bayou Watershed and determining nonpoint sources of pollution that contribute to these issues. With this knowledge, management programs and public outreach efforts have been developed to restore and protect the vital water resources of the watershed. Stakeholders are any individual or group that may be directly or indirectly affected by activities implemented to protect water quality such as citizens, businesses, municipalities, city and county governments, nonprofit organizations and state agencies. This document is a means by which stakeholders can become familiar with the Double Bayou Watershed and be active watershed stewards by making a difference in the quality and health of their streams through voluntary management practices. The document is a starting point to focus restoration efforts and enable financial and technical assistance to facilitate improvements in the Double Bayou Watershed. The Double Bayou Watershed Protection Plan is intended to be a living document, adjusted to include new data and modified as conditions in the watershed change over time. It will evolve as needs and circumstances dictate and will be guided by stakeholders as they undertake active stewardship of the watershed. iv Table of Contents Page Acknowledgements ......................................................................................................................... ii Statement of Purpose ..................................................................................................................... iv Table of Contents ............................................................................................................................ v List of Figures ................................................................................................................................ ix List of Tables ................................................................................................................................. xi Executive Summary ...................................................................................................................... xii 1 Watershed Management........................................................................................................ 14 1.1 What is a Watershed? ..................................................................................................... 14 1.2 Watersheds and Water Quality ....................................................................................... 14 1.3 Water Quality Standards ................................................................................................ 15 1.4 A Watershed Approach to Water Quality Management ................................................ 16 1.4.1 Watershed Approach ............................................................................................... 16 1.4.2 Watershed Protection Planning for Double Bayou ................................................. 16 2 State of the Double Bayou Watershed .................................................................................. 18 2.1 Double
