Bacteria Growth, Persistence, and Source Assessment in Rural Texas Landscapes and Streams

Project Goals and Objectives: Building upon results from TSSWCB Project 07-06 and further focusing on addressing informational needs identified in the “Bacteria TMDL Task Force R

Bacterial Source Tracking to Support Adaptive Management of the Arroyo Colorado Watershed Protection Plan

Project Description: The Arroyo Colorado currently has low dissolved oxygen levels within the tidal segment, not meeting the aquatic life use designated by the State of Texas and described in the Water Quality Standards. This has been the case for every 303(d) list prepared by the state since 1996. In addition, bacteria has always been a parameter of concern and as of 2006, the Arroyo became impaired due to high bacteria levels. There are many challenges associated with restoring water quality in the Arroyo Colorado Watershed.

Development of a Watershed Protection Plan for Attoyac Bayou

This project shall serve as a means for establishing and engaging a watershed stakeholder group to assist in the development and future implementation of a Watershed Protection Plan (WPP) for the Attoyac Bayou watershed. This project will utilize portions of the “Three-Tier Approach for Bacteria TMDL Development” as recommended in the Bacteria TMDL Task Force Report submitted to TCEQ and TSSWCB.

Surface Water Quality Monitoring to Support Development and Implementation of Bacteria TMDLs in the Copano Bay Watershed

Copano Bay is located in the San Antonio-Nueces Coastal Basin. The bay covers parts of Aransas and Refugio counties, while the watershed also encompasses Bee, Goliad, Karnes and San Patricio counties. Mission Bay and Port Bay are sub-bays of Copano Bay and are included in Segment 2472. Segment 2472 is the receiving body of the Mission and Aransas Rivers.

Surface Water Quality Monitoring to Support Plum Creek Watershed Protection Plan Development

Plum Creek rises in Hays County north of Kyle and runs south through Caldwell County, passing Lockhart and Luling, and eventually joins the San Marcos River at their confluence north of Gonzales County (see map below left). Plum Creek is 52 miles in length and has a drainage area of 389 mi2. According to the 2004 Texas Water Quality Inventory and 303(d) List, Plum Creek (Segment 1810) is impaired by elevated bacteria concentrations (category 5c) and exhibits nutrient enrichment concerns for ammonia, nitrate+nitrite nitrogen and total phosphorus.

Surface Water Quality Monitoring to Support the Implementation of the Lampasas River Watershed Protection Plan

Project Goals/Objectives: The goals of this project are one, generate data of known and acceptable quality for surface water quality monitoring of mainstem and tributary stations on the Lampasas River. Two, support the implementation of the Lampasas River WPP by collecting water quality data for use in evaluating the effectiveness of BMPs and in assessing water quality improvement.

Watershed Protection Plan Development for the Navasota River below Lake Limestone

Project Goals/Objectives: 1) Characterize current bacteria loadings and sources for the watershed 2) Determine needed levels of loading reduction to restore the waterbody 3) Work with watershed stakeholders to select and prioritize management measures needed to restore the waterbody 4) Develop a watershed protection plan for the Navasota River below Lake Limestone

Project Location: Navasota River below Lake Limetsone in Brazos, Grimes, Madison, Leon, Limestone and Robertson Counties

Project Costs: State ($210,532)
