The San Marcos River Foundation (SMRF) is a nonprofit 501(c)(3) corporation founded in 1985 during the Sesquicentennial celebration for the community by a small group of San Marcos citizens with a mission to preserve and protect the flow, natural beauty and purity of the San Marcos River.

You may contact us if you wish to learn about San Marcos River Foundation's work to protect the river - Phone Dianne Wassenich, Executive Director, at 512-353-4628 or
Email Diane at

If you want to learn about swimming, tubing, canoeing or other kinds of river recreation, check our River Info tab on this website and contact those businesses directly via their websites or phone numbers.  SMRF will not have the information you need about this, so it would be best to call the Tourist Information Center in San Marcos at 512-353-3435, if the many websites linked on our River Info tab do not supply all the information you need.
