A Note from Your Watershed Coordinator
Thank you so much to everyone who contributed to our 12th Annual Geronimo and Alligator Creeks Spring Cleanup in April – we had a wonderful event, with 158 volunteers who removed over 2,500 lbs. of waste from the watershed! Since the first cleanup in 2013, the watershed partnership has removed more than 40,000 lbs. of waste in total, all thanks to your support in donating, volunteering, and advertising for our project. If you want to join in our efforts to make a real difference in the community, be on the lookout for information about our Fall Cleanup coming October 4, 2025.
A quick announcement as we head into July – I will be going on maternity leave soon and expect to be back in late August or early September. Extensive planning has been done to ensure that there is no significant lapse in implementation of the watershed protection plan while I am gone. However, if you need anything in my absence, Dr. Jake Mowrer will be your main point of contact. He can be reached at jake.mowrer@ag.tamu.edu or 979-321-5916.
Best wishes,
Annalee Epps
Project Website Redesign
The Geronimo and Alligator Creeks Watershed Partnership relies on stakeholder involvement! This means we prioritize keeping you up to date on all the news, events, and information available about the project. While our website has filled this important role for many years, we recently got the opportunity to refresh and restructure the site to better serve you. We even got a beautiful new logo that better reflects the core values of the Partnership. Check it all out at geronimocreekwatershed.org!
Have thoughts or feedback on the new website or logo? We welcome your input! Email us today at geronimo.alligator@ag.tamu.edu.
Measurements Matter: pH
Is the water in Geronimo and Alligator Creeks acidic, neutral, or basic? How do we know the pH of the creek, and does it change over time? While these may not be questions you have considered before, pH plays an important role in many chemical and biological creek processes. But what does pH actually tell us about water quality in Geronimo and Alligator Creeks? This is the fifth article in our series exploring the water quality data collected in our watershed and why it matters.
A controlling factor in many chemical reactions, pH is a measure of Hydrogen ions (H+) in the water. It is often assessed using color-changing reagents on a water sample or with a sensor that is placed directly in the creek. Reported as a number between 1-14, pH is actually measured on a logarithmic scale, meaning a small change in the numeric value can reflect a huge change in H+ concentration. A larger number indicates a lower concentration of H+ in the water. In natural water bodies, pH usually ranges between 6.5-8. The normal pH of a creek is often determined by the soil and rocks that it flows through.
Changes in water pH can be caused by point or nonpoint source pollution. Shifts or fluctuation in pH can be a cause of immediate or long-term concern. The plants, fish, and insects that live in the creek are adapted to thrive in a specific pH range. If the pH leaves that range, species might migrate away or simply die off in that creek segment. Also, some metals and chemicals change form when exposed to a different pH and can become toxic (e.g. Copper and Ammonia). It is important to consider pH when assessing water quality and stream health. We measure pH because it matters!
