2022 River Symposium

Last Updated on January 30, 2024

The San Antonio River Authority (River Authority), in partnership with the San Antonio River Foundation, will host the 2nd Annual River Symposium on Saturday, September 24, 2022, from 9am to 4pm. Enjoy the day with kid activities, vendors, food trucks, a paddling race, and a tree giveaway. Plus, learn about the San Antonio River Watershed, also known as the San Antonio River Basin, and the River Authority’s mission with a variety of sessions and workshops. This event is FREE for the public to attend! Come grab a spot under the concrete petals of Confluence Park to listen and learn about what the River Authority does in your community.

What is the purpose of the River Symposium?

The River Symposium is designed to increase the community’s understanding of the San Antonio River Basin while also learning how the San Antonio River Authority works to harmonize the needs of people and the watershed sustainably. This annual event brings together area citizens, families, and professionals who share a common interest in the San Antonio River. This event also offers opportunities for the public to interact with River Authority professionals, collaborating governmental agencies, non-profit organizations, environmental and community advocates, and fellow citizens who are all working together to ensure area creeks and rivers remain healthy for generations to come.

Highlights from the 2021 River Symposium

The River Symposium is built around National Public Lands Day (September 24) and World Rivers Day (September 25) to serve as a “call to action” by inspiring attendees to become good stewards of area natural resources. This year the River Symposium will be held at Confluence Park (310 W. Mitchell Street in San Antonio, Texas). Confluence Park is a venue created by the San Antonio River Foundation, which enhances the efforts of diverse community organizations working to make a positive impact in San Antonio.

What is happening at the Symposium this year?

The 2022 Symposium will consist of a variety of activities and presentations about the San Antonio River. Kicking the day off, the “Mission Reach Rally” Paddling Race, which is the River Authority’s 3rd race in its Paddling Race Series, will showcase the Mission Reach Paddling Trail. After the race kicks off, head up to the concrete pavilion to enjoy FREE coffee and donuts and listen to a session by the River Authority’s General Manager Derek Boese, and the River Authority’s Board of Directors. They will not only be speaking about what the River Authority does but will also unveil the first glimpse of the new 2022 River Basin Report Card.

Mission Reach Area Maintenance

Update (December 2025):
Crews will be moving south of Concepcion Park towards the baseball fields around the Mission Road area. The trail in this section will be closed the morning of Wednesday 12/10 and is expected to reopen the later next week. 

Work will also continue at the current location near mile marker 8.2 for the remainder of the week, where crews will be cleaning the area and hauling off chips and debris. This section of the trail will remain open

When: Beginning October 20, 2025 through Spring 2026
What: Crews will be performing stem-density removal and related vegetation maintenance along sections of the Mission Reach to help manage flood risk and protect surrounding infrastructure. Some trails or segments may be closed temporarily while work is underway.
Why: Removing excess stems that naturally establish along the river helps maintain stormwater conveyance, reduces flood risk, and protects public infrastructure while allowing grassland and native vegetation to recover and thrive.
What to expect:

  • Limited trail closures and intermittent work zones.
  • Crews and equipment working near the riverbanks during daytime hours.
  • Parking areas remain open, but visitors may see signage and temporary barriers.

Questions? Call the San Antonio River Authority at (210) 227-1373 or visit https://www.sariverauthority.org/services/river-health/ecosystems/.

Thank you for your patience while we keep the Mission Reach safe, clean, and enjoyable.
