Mission Statement

The Tryon Creek Watershed Council restores, protects and enhances the ecological health and function of our unique urban watershed.

What We Do

The majority of TCWC projects involve restoration of riparian native vegetation on streambanks.  We focus these projects on private properties along key wildlife corridors, neighboring green-spaces, and adjacent to existing restoration sites.  We also fix fish passage barriers by contracting replacement with a bridge (such as the case with the Stone Bridge Project on Nettle Creek) or working as an advocate (in the case of Boones Ferry Culvert and the Highway 43 Culvert projects).  As a watershed council, another key role that we fill is coordination of partnerships, watershed planning, and monitoring.


The Council has been actively bringing the community together since 1994 when a small group of concerned citizens joined forces to become stewards of our natural heritage.  TCWC worked under the fiscal sponsorship of Southwest Neighborhoods, Inc. and then the Friends of Tryon Creek until receiving 501(c)(3) status in 2014.

Non Profit Status

Tryon Creek Watershed Council is a public charity under section 501(c)(3) of the internal revenue code.   Donations are deductible as allowed legally. Our EIN number is 46-3898313.
