  1. Physical and Chemical Parameters of Jones Pond David Burbank Reid Camp Will Langford Donella Miller

  2. Outline • Objectives • Methods • Results • Discussion • Recommendations

  3. Objectives • Construct bathymetric map • Water Volume • Sediment Volume • Depths • Parameter Profiles • Temperature • Dissolved Oxygen • Light • Conductivity • Total Phosphorus • Chlorophyll a

  4. Methods • Temperature, Conductivity, D.O. • YSI 85 • ½ meter intervals • Irradiance • Photometer • ½ meter intervals • 1% surface irradiance • GPS/Depth Finder/GIS • Navigate pond in grid • Bathymetric Map www.rickly.com misclab.umeoce.maine.edu

  5. Methods • Total Phosphorus • Van Dorn Sampler • Triplicate 20ml Samples every 1 meter • P-Tubes (Potassium Persulphate) • Analysis • Chlorophyll a • Triplicate Sample every 1 meter • Integrated • Analysis www.wildco.com www.superstock.com

  6. Results • Profiles

  7. Results • Profiles Continued

  8. Results • Total Phosphorus/Chlorophyll a

  9. Results • Pond Area • 670.9 m2 • Water Volume • 1315.04 m3 • Depth • Average= .51 m • Max= 2.80 m

  10. Discussion • High Conductivity • Spring Valley - <70 • Jones Pond - >326 • Temperature Profile • Isothermic • No Thermocline • Low D.O. • Clinograde Profile • T.P. • Increases With Depth • Within Eutrophic Limits • Chlorophyll a • Even Dispersal • Within Eutrophic Limits

  11. Recommendations • Sample Again at Different Times • Determine if actually eutrophic • Mixing events • Low D.O. • Aerators • Aquatic Plants (P/S) • Fishery Capable? • Winter Kill – Low D.O. + Freeze • D.O. Raised and Monitored www.keetonaqua.com tinyfarmblog.com
