Owasco Lake & Watershed Data

Bi-Monthly Nutrient Loading Survey 2006 & 2007

• Initiated in 2006
• Eleven Lake Sites, collecting:
  • SeaBird CTD Cast - Conductivity, Temperature, Light Transmission vs. Depth
  • Horizontal & Vertical Plankton Tows & Abundance Enumerations
  • Secchi Disk Depth
  • Surface & Bottom (few meters above lake floor) Water Samples analyzed for:
    • Total Coliform and E. coli bacteria (only in 2005)
    • Total Phosphates
    • Dissolved Nutrients (Phosphates, Nitrates, & Silica)
    • DO, pH, Conductivity (Specific Conductance)
    • Chlorophyll a
    • Total Suspended Solids
    • Major Ions (Cl, SO4, Na, K, Ca, Mg by IC) & Alkalinity (by titration)
• 7 Tributary Sites, collecting:
  • Stream Discharge
  • Temperature, pH, Dissolved Oxygen, Conductivity
  • Grab Sample analyzed for:
    • Total Phosphate
    • Dissolved Nutrients (Phosphates, Nitrates, & Silica)
    • Total Suspended Solids
    • Major Ions (Cl, SO4, Na, K, Ca, Mg by IC) & Alkalinity (by titration)
