Flatwater’s Dam That Cancer Presented by TYLER’S is the premier fundraising event for Flatwater.
Monday June 8, 2026
No one faces cancer alone with Flatwater. Every dollar raised through Flatwater’s Dam That Cancer Presented by TYLER’S goes directly toward providing access to mental health therapy for individuals, couples, and families facing the emotional toll of cancer.
Now in its 17th year, Dam That Cancer (DTC) is Flatwater’s premier annual fundraising event - a community-powered day on Lake Austin that brings people together on and off the water in support of mental health care when it’s needed most. In 2025, the DTC community raised $1.53 million for Flatwater.
The impact is real - thousands of therapy sessions delivered at no cost to Central Texans navigating the emotional and financial toll of cancer.
An Event Built for everyone
Dam That Cancer is inclusive, welcoming, and approachable! You don’t need to be an experienced paddle boarder or have participated before to be apart of it.
Whether you’re on the water, supporting from land, or gathering with the community, there’s a place for everyone at DTC.
Flatwater’s Dam That Cancer is for:
Anyone impacted by cancer - directly or indirectly
Friends, family members, caregivers, and supporters
People who care deeply about mental health access
First-time paddlers and seasoned participants alike
Anyone looking for a meaningful way to give back and show up
Our community includes
a celebration for the community
What to Expect:
A 10-hour, 21-mile paddle, followed by a celebration rooted in community and connection.
This is not a race. We paddle together, take frequent regroup and water/snack breaks, and make sure no one is left behind - every paddler is supported from start to finish!
A mandatory paddler safety meeting the day before where participants will review on-the-water expectations and pick up their event swag.
Trained safety leads + support boats on the water, ensuring paddlers are supported throughout the entire route.
The DTC Post-Paddle Party, open to everyone
Highly recommended training paddles will be available ahead of the event - a great way to build confidence and connect with the community!
After the paddle, the celebration continues - everyone of all ages are invited to come out, gather, and support Flatwater’s mission at the LCRA Red Bud Center from 6-8 PM.
Local food + drinks
Local vendors + photo booth fun
Giveaway swag and chances to win prizes
Kid-friendly activities
A celebratory, welcoming atmosphere for all
You don’t need to be a paddler to attend. Come out, gather, and celebrate the impact we’re making together!
