Upper San Antonio River Watershed Protection Plan

The San Antonio River Authority (SARA) is worked in conjunction with the City of San Antonio, Bexar County and other partners to develop a basin-wide Watershed Protection Plan (WPP). A WPP serves as a guide to address non-point source pollution. The overall water quality goal of the implemented WPP is to reduce bacteria levels so that the uppermost reach of the Upper San Antonio River is compliant with the State Water Quality Stream Standards. Phase I of the WPP will complement the Total Maximum Daily Load (TMDL) activities by establishing the framework needed for implementation through public outreach, awareness and input efforts, as well as collaboration with partners and stakeholders.
The watershed protection plan (WPP) is a living document that is the basis of efforts to improve and protect water quality in the Upper San Antonio River Watershed. This document provides guidance to the Bexar Regional Watershed Management Partnership members to address water quality issues in a collaborative manner, rather than individually.

Upper San Antonio River Watershed Protection Plan Revision

In an effort to enhance the urban reaches of the Upper San Antonio River (segment 1911) and improve and protect water quality, the San Antonio River Authority (SARA) is proposing to update, revise and begin implementing the 2006 Upper San Antonio River Watershed Protection Plan (WPP). The revised WPP will identify and propose water quality Best Management Practices (BMPs) that would serve to abate or control non-point source pollution of fecal coliform bacteria, sediments and excess nutrients (nitrogen and phosphorous). The water quality goals of the project are to develop a plan for implementation of approved BMPs that would aid in reducing E. coli bacteria non-point source (NPS) loads to segment 1911 of the San Antonio River. SARA and the Bexar Regional Watershed Management (BRWM) partnership objectives are to have the Upper San Antonio River compliant with the State of Texas Surface Water Quality Contact Recreation Standard which is less than 126 E. coli organisms per 100 milliliters.

SARA, with input from BRWM partners, will develop an inventory of water quality BMPs some developed as part of the 2006 WPP along with other BMPs that were developed and/or implemented after the 2006 WPP was finalized.

During the course of the project, James Miertschin and Associates, with the assistance of SARA, will identify the types of BMPs best suited to reduce non-point source pollution along the impaired reaches of the Upper San Antonio River and determine locations (including tributaries) where installation would be most effective, economical and complimentary to the ecosystem. Installation and implementation will be coordinated and phased with planned re-developments, flood control or parkway structures, features, and amenities. Following the implementation of the new BMPs. SARA will monitor instream water quality to assess the effectiveness of the BMP's over time.
