  1. A Brief Overview of the physical limnology of Otsego Lake By Liam Heiland

  2. Low concentration of nutrients Few producers High transparency High oxygen concentration All phosphorus from external sources

  3. High concentration of nutrients Many producers Low transparency Low oxygen concentration Internal phosphorus loading

  6. Lake Trout Require: Temperatures 4 – 14o Celsius 6 mg/l of dissolved oxygen

  7. Otsego Lake Dissolved Oxygen, 1988

  8. Decreased Clarity of Water • Mean temperature decrease • Overall Increase in Photosynthetic Algae Population • D/O Decrease • Increased decomposition • Increased Phosphorus release from sediment • increased movement towards Eutrophic conditions. • Thiamine (vitamin B-1) deficiency • Early Mortality Syndrome in Trout Fry • Not exhibited by Otsego Lake Trout- This must be investigated

  9. Otsego Lake Dissolved Oxygen, 1993

  10. Walleye Require: Temperatures 4 - 30o Celsius 3 mg/l of dissolved oxygen

  11. Otsego Lake Dissolved Oxygen, 2004

  12. Otsego Lake Dissolved Oxygen, 2008
