ACWA was formed in 1998 by a group of concerned citizens. These dedicated volunteers wanted to give Anderson Creek a voice, and worked to coordinate efforts and bring attention to the neglected stream. In these early days the watershed had two committees within it working to improve streams. One group worked in the upper reaches of the stream and the other worked in the lower. Together they hoped to restore the watershed entirely.
The efforts of the two committees were combined and the meeting location moved to the lower sections of the watershed. Over the years the group has worked to increase public awareness and support for the restoration work. This has included on the ground projects, assessments of the stream, and education efforts in the watershed. The ACWA has worked to plant trees in the watershed and pick up garbage from dump sites.
