Big Bend Chapter

Sierra Club Program – Sierra Club Explores Water Resources, October 23

**ARCHIVED POST **

[from Dallas Baxter]

The Big Bend group of the Sierra Club will meet from 7:15 to 9 p.m. Wednesday, October 23 at the Alpine Public Library to explore water resources in the Tri-counties.

Water, or the lack of it, impacts every part of the area. Growth as well as threats are coming into the Texas Big Bend. The program will offer information about them and about how to meet them.

“We need to understand our water resources in order for us to take steps to better protect the resources we have now and in the future,” said J.D. Newsom, executive director of the Big Bend Conservation alliance and one of the presenters. “Water conservation can play a part but, more importantly, better planning and policy will be necessary,” he said.

Also presenting is Dr. Kevin Urbanczyk, Sul Ross professor, who will give participants a good base understanding of area water resources and current modeling. He will also talk about the region’s desired future conditions. With that understanding strategies can be developed to better protect area water resources.

The community is encouraged to take this opportunity to learn more about this important challenge. Sierra Club membership information will be available at the meeting.

The Alpine Public Library is located on 13th St., between Sul Ross Avenue and Avenue E in Alpine.

About the Region

Fall Symposium 2025 Logo - Teach for the Future

Salado, the location of our Fall 2025 Symposium, lies at the intersection of two ecoregions: the Edwards Plateau (Limestone Cut Plain) and Blackland Prairie (Northern Blackland Prairie).

The Edwards Plateau area is also called the Hill Country; however, this general term covers a much larger area extending farther north. Spring-fed creeks are found throughout the region; deep limestone canyons, rivers, and lakes (reservoirs) are common. Ashe juniper is perhaps the most common woody species found throughout the region. Additional woody species include various species of oak, with live oak (Quercus fusiformis) being the most common. Sycamores (Platanus occidentalis) and bald cypress (Taxodium distichum) border waterways. This area is well known for its spring wildflower displays, though they may be viewed in spring, late summer, and fall, as well. According to Texas Parks and Wildlife, average annual rainfall in the Edwards Plateau ranges from 15 to 34 inches.

The Blackland Prairie extends from the Red River south to San Antonio, bordered on the west by the Edwards Plateau and the Cross Timbers, and on the east by the Post Oak Savannah. Annual rainfall averages 30 to 40 inches, with higher averages to the east. This region is dominated by prairie species. The most common grass species include little bluestem (Schizachyrium scoparium) and Indian grass (Sorghastrum nutans) in the uplands and switchgrass (Panicum virgatum) in the riparian areas and drainages. Common herbaceous flowering plants include salvias, penstemons, and silphiums. This area has suffered greatly from overgrazing and agricultural use. Few intact areas remain, though many of the plants can be found along county roadsides throughout the region.

Our fall Symposium host chapter, the Tonkawa Chapter, includes both of these ecoregions.
