A comprehensive stream assessment was completed by the PSWCD using the Rapid

Assessment of Stream Conditions Along Length (RASCAL) tool, which is one way to gain

firsthand knowledge of the existing conditions in a stream. This tool allows priority areas

in the stream to be identified for targeted conservation practices. These practices would

reduce pollutant loading by amending adjacent land use, restoring habitat, and stabilizing

banks. Data was collected including observed gullies, exposed utilities, tile outfalls, and

storm sewers. A GPS camera was frequently used to document these points of interest and

keep track of stream conditions.

The bedrock of the Fourmile Creek watershed consists of marine sedimentary rocks deposited over 350 million years ago
