Near Real Time Data & Owasco Lake/Watershed Study

Seneca Lake Water Quality and Meteorological Buoy

Owasco Lake/Watershed Study

Comparative Limnology & Hydrogeochemistry of the Finger Lakes - Sites

Monthly Monitoring Program

• Initiated in 2005
• Seven Lakes: Skaneateles, Owasco, Cayuga, Seneca, Keuka, Canandaigua, Honeoye Lakes
• At least Two Deep-Water Sites per Lake, 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)
    • Dissolved Nutrients (Phosphates, Nitrates, & Silica)
    • Total Phosphates (starting in 2006)
    • DO, pH, Conductivity (Specific Conductance)
    • Chlorophyll a
    • Total Suspended Solids
    • Major Ions (Cl, SO4, Na, K, Ca, Mg by IC) & Alkalinity (by titration)
