40 What is the data telling us? 2. Does flow seem to have an effect on WQ indicators? If so, how? Increasing flow  TSS  Alk  Nitr Decreasing flow  FC

41 What is the data telling us? 3. Do any data suggest that point sources may be impacting the stream? If so, which indicators?

42 What is the data telling us? 3. Do any data suggest that point sources may be impacting the stream? If so, which indicators? Discharge #7 (WWTP) – high FC at CC3

43 4.Do any data suggest that non-point source pollution may be impacting the stream? If so, which indicators?

44 Ag runoff to SB1 – high FC Ag runoff to EB1 – high nitrate with high flow (check into further)

45 5.Overall, what would you say about the health of the College Creek Watershed?

46 WB1 (sandstone) & EB1 (limestone) baseline conditions WQ at CC3 significantly degraded

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

48 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
