3. Cedar Lake Water Clarity FTU’s Schmidt’s Pte (#1) & Briarwood Bay (#2) Sampling Sites 2008 - 2012
Our colorimeter FTU readings were calibrated to equal EPA NTU’s using a formazin solution as prescribed in the colorimeter operator’s manual. No standard found on NTU/FTU turbidity readings in lakes; grossly, less then 50 is required for a healthy fishery.

4. Color Analysis – Platinum Cobalt Method – 2010 – 2012
Color in water may be attributed to humus, peat, plankton , vegetation, and natural metallic ions, such as iron, manganese or industrial waste. The Platinum cobalt method is a visual method of color measurement of essentially light colored liquids with color characteristics close to those of the platinum cobalt scale. Those characteristics are generally described as “yellowish brown”. The measurement range is from 0 – Distilled water is “0”. The permissible drinking water color limit in India is “5”.

12. Lake pH at Schmidt’s Pte & Briarwood Bay Sample Sites 2002 – 2012
Legend: S = Shmidt’s Pte, B = Briarwood Bay
After our pH gauge broke on 7/1/10, a new pH gauge was put into service on 7/30/10. It is more accurate & double calibrated. Starting in 2011 it was calibrated at 4.0, 7.0 & 10.0 for greatest accuracy.

17. Toxic Unionized Ammonia 2008 – 2012 Parts Per Million (PPM)
Readings Above .02 indicate Toxic Unionized Ammonia (NH(sub3)) is nearing the danger zone
Readings above .03 indicate Toxic Unionized Ammonia (NH(sub3)) is in the danger zone
Readings above .07 are so rare that to depict them changes the axis of the chart and the majority of the readings become difficult to distinguish gathered at the bottom of the chart. Therefore, all readings above .07 will be depicted as Check the body of the report for more specificity on those readings
