Watershed Matchup #2: Clear Creek VS Clear Creek

This post is part of a series for 2019 Watershed Awareness Month, comparing water quality in a pair of local creeks to learn how land and people influence water. Clear Creek @Hyland on May 18 Clear Creek@ Hyland on May 24 Transparency > 60 cm Transparency of 1 cm Orthophosphate 0.1 mg/L Orthophosphate 5 mg/L Clear Creek was true to its name on May 18 when the Squaw Creek Watershed Coalition did its spring water quality snapshot.  Long-time member Ed Engle and three Ames High School students (Wil, Becca, and Nate) filled a transparency tube to the top (60 cm) and the secchi disk at the bottom was clearly visible.  A week later, Rick Dietz tested the same location after a 1.7 inch rainstorm and couldn’t see the disk until he’d poured out all but 1 cm of the water!
