2026 Water Wonks Hour Lecture Series #1
2026-01-28 15:30 - 16:30 | zoom

2026 Water Wonks Hour Lecture Series #2: Building a Grassroots Movement to Protect Urban Waterways in San Antonio

Brendan Gibbons will discuss River Aid San Antonio’s (RASA’s) efforts to raise an army of volunteer stewards to help keep the San Antonio River and its tributaries clean and thriving. RASA hosts multiple watershed cleanup events per month where volunteers remove thousands of pounds of litter from streams. Since the group’s founding, RASA volunteers have removed more than 600,000 pounds of waste from the San Antonio River and its tributaries. RASA has also accepted the leadership baton for Basura Bash, the largest single-day trash cleanup event in Texas, an event that drew 2,130 volunteers in 2025, its 30th year. Gibbons will also discuss RASA’s small but growing network of water quality monitoring sites via Texas Stream Team, which trains citizen scientists to conduct monthly water quality monitoring of local waterways. Gibbons will also detail RASA’s partnership with GEAA on a water quality retrofit on HOA property at Lorence Creek, which helps improve the quality of stormwater flowing into the Edwards Aquifer Recharge Zone.

Some of the tools Municipal and Private Water Utilities use to protect the water supply are very similar while other methodologies seem very different.

Water Wonks Hour Lecture Series #7: San Antonio’s Growing Heat Challenge
2026-07-22 15:30 - 16:30 | zoom
This presentation explores how extreme heat is impacting San Antonio and Bexar County, including how to measure human heat stress and respond to it. Globally, 2023–2025 are the hottest years ever recorded, and Earth is now warmer than at any time in over 120,000 years .
Locally, San Antonio ranks among the U.S. cities with the biggest rise in days above 95°F, and days over 100°F are becoming far more common .
The official air temperature at the Airport is measured in the shade and does not reflect the true heat people feel across various neighborhoods. Surface temperatures can exceed 140–160°F, creating real risks of burns and heat illness.
Better tools for measuring heat stress, including Heat Index, Wet Bulb Globe Temperature, and HeatRisk are explained. The presentation highlights some practical solutions including: shade, hydration stations, misting, atmospheric water harvesting, pervious pavement, geothermal cooling, passive daytime radiative cooling, and the planning of cool oases connected by cool corridors.
