2. Parameters We compared these parameters;pH
Nitrate conc.
Turbidity
Chlorophyll
Dissolved Oxygen
Between five lakes; Arbutus, Catlin, Green, Oneida, Onondaga, and Wolf.

3. Why are these parameters of interest?
These parameters allow assumptions to be made of the type of organisms present.
Fish communities, macrophytes, macroinvertebrates, phytoplankton and zooplankton all require specific conditions to survive.

4. Data was collected during the Fall 2006, on a weekly basis over a 2 month period.
A multi-probe was used to collect the data.

5. Chlorophyll- Oneida Lake vs. Green Lake

6. Chlorophyll
Oneida Lake shows a significant jump in chlorophyll at the bottom of the lake.
Green Lake has a large spike in chlorophyll at 20 meters, then decreases again as you approach 50 meters.

7. Arbutus vs. Onondaga Lake Chlorophyll

8. Turbidity

9. Nitrate Concentrations

10. Nitrate Conc. Cont’d.

11. pH levels

12. pH levels

13. Dissolved Oxygen %

14. Dissolved Oxygen %

15. Conclusion
These measurements are sufficient for our purposes, however, sources of error include;
Variable weather conditions,
Data collected on different days
Data collected by different people
Personal error when sampling
