1. Water Chemistry of Local Lakes
Mike Bednarski, Danielle Tommaso & Dan Zapf

2. Why Chemistry? Nutrients Trophic state analysis Basis of food chain

3. What did we do? Sampled six lakes Water sampling Back at the lab
Phosphorous analysis

4. Results

5. What does it all mean? Phosphorous indicator of :
Nutrient amount in lake
Trophic state
Eutrophic
Mesotrophic
Oligotrophic
Dystrophic

6. Eutrophic Lakes High Phosphorous Very productive Onondaga Lake, Oneida
Algae blooms
Onondaga Lake, Oneida
Lake

7. Mesotrophic Lakes
“Middle fed”
Mid-nutrient levels
Mid-productivity

8. Oligotrophic Lakes Low phosphorous Low productivity Clear water
Green Lake, Catlin
Lake

9. Dystrophic “Black water stained” lakes Suspended organic material
Rich Lake, Arbutus Lake

10. What else?
Measure other parameters to further understand trophic states
