Oral Clackamas High School, Clackamas, OR Andrew Gilford We used ArcGIS, a software mapping program, to analyze watershed health in the Clackamas Watershed.

The second map was able to demonstrate overlap between high areas of aquatic diversity and high levels of pollution.

SWRP data showing number of insect orders was taken from Clear Creek and Deep Creek over the last thre
