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

Why Chemistry? Nutrients Trophic state analysis Basis of food chain http://www.kenshowalter.com/26413.html

What did we do? Sampled six lakes Water sampling Back at the lab Phosphorous analysis http://www.cnr.vt.edu/fisheries/afs/fisheries_techniques/Chapter4/Removal%20of%20water%20from%20a%20kemmerer%20water%20sampler.jpg

Results

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

Eutrophic Lakes High Phosphorous Very productive Onondaga Lake, Oneida Algae blooms Onondaga Lake, Oneida Lake http://upstatefreshwater.org/html/onondaga_lake.html http://visibleearth.nasa.gov/data/ev27/ev2795_S2000104100904_md.jpg

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

Oligotrophic Lakes Low phosphorous Low productivity Clear water Green Lake, Catlin Lake http://remote.ucdavis.edu/remote%20images/Tahoe/Tahoe_view.jpg

Dystrophic “Black water stained” lakes Suspended organic material Rich Lake, Arbutus Lake http://www.esf.edu/research/sponprog/reports/research/photos/forprop.jpg

What else? Measure other parameters to further understand trophic states http://www.adirondacklakessurvey.org/pics/Arbutus.jpg http://www.nywea.org/clearwaters/gif/314040b.jpg
