When the Tanana River bridge was installed in Salcha, Alaska, the community worried about the levee's effects on fish wildlife. Salcha Elementary School, along with the help of Tanana Valley Watershed Association, conducted a 10-year scientific project with students to study the effects the levee had on Piledriver Slough. Tori Brannan - the filmmaker's mother - is a retired principal at Salcha Elementary and was the project's centerpiece. She shares her experiences with the project, the community, and how her daughter's involvement strengthened their relationship.
