Geronimo and Alligator Creeks

8th Annual Geronimo and Alligator Creeks Clean Up Event

To comply with Texas A&M AgriLife Extension Service and the Centers for Disease Control and Prevention directives designed to protect public health, the 8th Annual Geronimo and Alligator Creeks Clean Up Event has been postponed.

I want to thank everyone who registered to volunteer their time and energy - without you, an event like this is not possible.

I also want to thank our sponsors who have contributed financially, as well as, with donations of bottled water, waste disposal, meeting location space, and trailer drivers - without our sponsors, we would not be able to provide the special event T-shirts, breakfast tacos, refreshments, as well as a host of other services.

Our sponsors include: Alamo Group, City of New Braunfels, Commissioner Drew Englelke, Ehler's Tree Farm, Geronimo General Store, Guadalupe-Blanco River Authority, Guadalupe County Groundwater Conservation District, Heinemeyer Farms, Irma Lewis Seguin Outdoor Learning Center, Niagara Bottling, Thrivent Financial, and Waste Connections.

I anticipate rescheduling the Clean Up Event for the fall, and will contact you as soon as a new date is scheduled.

As always, you can check back here for updates. Please contact me with any questions or issues.

Thank you,
Ward Ling

Feral Hog sightings or damage?

There is a new, innovative tool that will let landowners easily report wild pig activity and damage. Read more about it here.

The reporting tool is part of the Texas A&M Natural Resources Institute - Wild Pigs website. Click on the "Report Wild Pigs" link for the reporting tool.


Geronimo Creek and its tributary Alligator Creek are located in Comal and Guadalupe Counties, and lie within the larger Guadalupe River Basin. The headwaters of Alligator Creek begin in southeastern Comal County, just above Interstate 35 near New Braunfels. Alligator Creek flows southeast towards Seguin until about midway in the watershed where it joins Geronimo Creek. The majority of the Alligator Creek watershed lies within the extra-territorial jurisdiction (ETJ) of New Braunfels, while the majority of the Geronimo Creek watershed is almost entirely within the ETJ of Seguin.

Water Quality

Geronimo Creek is monitored by the Guadalupe-Blanco River Authority (GBRA) as part of the Clean Rivers Program. Geronimo Creek is listed on the Texas 303(d) List with a concern for nitrate-nitrogen and an impairment of the contact recreation use, due to elevated E.coli bacteria concentrations.

Public Response to Impaired Water Quality

Starting in 2009, development of the Geronimo and Alligator Creeks Watershed Protection Plan (WPP) was initiated by local stakeholders with the primary goal being to restore and protect water quality and designated uses of the creeks through voluntary, non-regulatory water resource management. Shortly after development of the WPP was completed, it was accepted by EPA on September 13, 2012.

How You Can Be Involved

Public participation is critical throughout implementation, as ultimate success of any WPP depends on stewardship of the land and water resources by landowners, businesses, elected officials, and residents of the watershed. The Geronimo and Alligator Creeks WPP defines strategies and identifies opportunities for stakeholders across the watershed to work together and as individuals to implement voluntary practices and programs that will restore and protect water quality.

You can become an active member of the Partnership by participating in meetings, signing up for email updates, and becoming involved in implementation of the WPP, as well as telling others about this important project! Simply contact Dr. Evgenia Spears under the Contact Us tab.
