Watershed Protection Planning for the Dry Comal Creek & Comal River

 

The City of New Braunfels is currently moving forward with the development of a Watershed Protection Plan (WPP) to address bacteria concerns in the Dry Comal Creek and Comal River watersheds.Phase One of the Dry Comal Creek/ Comal River Watershed Protection Plan kicked off in August 2015 and includes efforts to characterize the watershed, assemble a working stakeholder group and define bacteria load reductions needed to meet applicable water quality standards for bacteria. Phase Two will involve continued stakeholder involvement, identification of bacteria management measures, and development of a watershed protection plan. Phase Two of the Dry Comal Creek/ Comal River WPP will commence as Phase One is completed and grant funding is secured through the Texas Commission on Environmental Quality (TCEQ). Partners on the Dry Comal Creek/ Comal River WPP include the City of New Braunfels, ARCADIS, TCEQ, Edwards Aquifer Authority and Guadalupe Blanco River Authority (GBRA).

Historical data collected by GBRA as part of ongoing Clean Rivers Program sampling identified Dry Comal Creek (Segment 1811A) as impaired for bacteria. Segment 1811A was initially included on the 303(d) list in 2010. In 2011, the City of New Braunfels proactively initiated a bacteria monitoring program on Dry Comal Creek to supplement data collected as part of the Clean Rivers Program monitoring conducted by GBRA. The City of New Braunfels also initiated a supplemental bacteria monitoring program on the Comal River to address increasing bacteria levels in the Comal River watershed. A preliminary bacteria source tracking (BST) analysis was conducted in 2013 to help identify potential bacteria sources on the Dry Comal Creek and the Comal River. The preliminary BST analysis indicated significant contributions from wildlife. In 2014, GBRA added an additional monitoring location on the Comal River in Landa Park, upstream of the confluence with Dry Comal Creek, to help assess the impact of elevated Dry Comal Creek bacteria concentrations on the Comal River. The project team is utilizing all existing water quality data from the Dry Comal Creek and Comal River to support water quality modeling efforts and to help identify bacteria loading trends.  Water quality data collected by the GBRA on the Dry Comal Creek and the Comal River as part of the Clean Rivers Program can be found on the GBRA website at the link below:

The City of New Braunfels and the project team is looking forward to working with local stakeholders and partners to solidify the watershed protection plan and to ultimately improve water quality within the Dry Comal Creek and Comal River watersheds.

The Dry Comal Creek/ Comal River WPP is one of the many watershed protection planning efforts occurring within the state of Texas. A listing of WPPs in Texas can be found via the link below:

Dry Comal Creek/ Comal River Stakeholder Group

 

Local public involvement is imperative for the successful development and implementation of a watershed protection plan. Therefore, the Dry Comal Creek/ Comal River WPP project team has assembled a stakeholder group to gather pertinent information regarding the watershed, assist with public outreach, and guide the overall planning process. The existing stakeholder group includes riparian landowners, agricultural interests, county/ city officials, citizen groups, environmental groups, educators, local wildlife agencies, developers, and business/ industry representatives.

Since November 2015, three stakeholder group meetings have been held. The presentations from the WPP stakeholder meetings can be view via the links below:

-November 9th, 2015 WPP Stakeholder meeting presentation;
-February 17th, 2016 WPP Stakeholder meeting presentation;
-May 5th, 2016 WPP Stakeholder meeting presentation;
-October 24th, 2016 WPP Stakeholder meeting presentation.
  

Dry Comal Creek/ Comal River WPP Work Groups

WPP Stakeholder Work Groups have been formed in order to identify and develop watershed-specific recommendations for managing bacteria inputs to the Dry Comal Creek and Comal River.

The WPP Work Groups include:

        1) Urban Stormwater and Infrastructure
        2) Wildlife Management
        3) Agriculture/ Livestock
        4) Outreach and Education
 
The first meeting of the WPP Work Groups will be on Monday, December 5th at the City of New Braunfels City Hall located at 550 Landa Street.
 

Texas Watershed Stewards Workshop!!!

The City of New Braunfels will be hosting a Texas Watershed Steward Workshop on Tuesday, February 7th. The workshop will be led by Texas A&M AgriLife. The workshop will begin at 8am at the City of New Braunfels City Hall (550 Landa Street, New Braunfels, TX 78130). You can register for the workshop at the following link: http://tws.tamu.edu/workshops/upcoming-workshops/.
 


Overview of the Watersheds

 

Dry Comal Creek

The Dry Comal Creek watershed is a large watershed located in Comal County. The headwaters of the Dry Comal Creek are located south of Canyon Reservoir. The creek is approximately 35 miles long with a catchment area of approximately 111 square miles. The Dry Comal Creek contributes flow to the Comal River at its confluence within the City of New Braunfels.

Comal River


The Comal River begins in Landa Park in the heart of New Braunfels, TX as water from the Comal Springs discharges from the Edwards Aquifer along the Balcones Fault Zone. Average springflow from the Comal springs is more than 300 cubic feet per second! The Comal River is the shortest navigable river in Texas at 2 1/2 miles long. The river offers excellent water recreation opportunities and is also home to several endangered species.

Three Tips for Reducing Bacteria Loading:
   
   
  1. Avoid feeding wildlife including deer, ducks, and geese. Feeding wildlife can lead to concentrated populations of animals which may result in increased bacteria content in our local waterways. Concentrated populations of wildlife can also result in the proliferation of harmful diseases among the animals. Feeding of wildlife is unhealthy for the wildlife themselves as decreases their ability to locate food on their own. Please view the information from the Texas Parks and Wildlife Department regarding the negative impacts of feeding ducks: https://www.youtube.com/watch?v=oCPAAmlNXxI
  2. Pick-up after your pet! Pet waste can be a significant source of bacteria in our rivers and creeks.
  3. Perform routine maintenance of your septic system! It is recommended that your septic system be inspected regularly and pumped every 3-5 years. Additional information regarding septic system maintenance can be found by following this link (TCEQ: Basics for Septic Systems)
