5. Overall, what would you say about the health of the College Creek Watershed?
![Page 46: Water Quality Data Interpretation](https://reader035.vdocument.in/reader035/viewer/2022062221/5681452f550346895db1f649/html5/thumbnails/46.jpg)
5. Overall, what would you say about the health of the College Creek Watershed?
• WB1 (sandstone) & EB1 (limestone) baseline conditions
• WQ at CC3 significantly degraded

6. If this was your watershed, what are some ways to improve the condition of the stream and raise awareness in the community?

6. If this was your watershed, what are some ways to improve the condition of the stream and raise awareness in the community?
• Investigate non-point source Ag inputs above SB1 – education & outreach?
• WWTP – investigate summer discharges• Protect summer baseflows and water temp
– riparian vegetation and wetland creation
