What started as a science field project for Del City High School students turned into a major creek cleanup effort that so impressed our judges they said it deserved national attention. After the students conducted a scientifically measured stream quality survey on Crutcho Creek adjacent to the school, the "poor" grade it received spurred them into action.

They studied floodplain maps and studied nonpoint sources of pollution. Then they worked throughout the summer to develop a work plan, collect supplies and secure funding. Finally, a week was set aside in September for cleaning a two-mile stretch of the creek, and 186 volunteers contributed hundreds of difficult hours.

The results? In just one year, the creek's rating has jumped from "poor" to "good" and the diversity of organisms has increased. For turning a school science class study into a project with impressive benefits for the students and the whole community, Del City High School is good news for the waterways of Oklahoma.
