Staff & Board

TRK is proud to have been born out of activism which represented the first application of the Clean Water Act in the country in 1986, when local citizens came together to demand the government clean up a polluted river that had long since exceeded maximum daily pollution load limits, with 13,800 plant violations cited. Today the Tualatin River is much cleaner, but development challenges remain and we seek to inspire new generations of river ambassadors who will bring the message of clean water and its link to the economy, human health, and ecology to the forefront.
