  1. The Peter’s Kill and Lake Minnewaska Arlington High School Field Trip Data

  2. The Peter’s Kill is a stream that flows out of Lake Awosting. • We are sampling at the gate house to Lake Minnewaska. • We sampled on both sides of the bridge. The Peter’s Kill Site

  3. Summary of Observations on Oct. 28, 2010 Color of creek – Golden yellow Temperature – 9.5 oC Conductivity – 28 uS Visibility – to the bottom (.25m) pH of creek – 4.7 Dissolved Oxygen – 9.2mg/L Nitrates – 0ppm Phosphates – 0ppm Presence of tannins – Yes Presence of animal life - No The Peter’s Kill

  4. Visibility measured with a Sechhi Disc = .25 m (to bottom) Peter’s Kill

  5. Temperature and conductivity– using a YSI temp/salinity/conductivity probe = 9.5oC, 28 uS Peter’s Kill

  6. pH of Creek using a Pasco pH meter calibrated with 3 test buffers (accuracy +/- 0.2) = 4.7 Peter’s Kill

  7. Dissolved Oxygen using LaMotte test kits (modified Winkler titration) = 9.2 mg/l Peter’s Kill

  8. Nitrate and Phosphates using Lamotte test kits = 0ppm Peter’s Kill

  9. Presence of tannins = yes • Presence of animal life = no Peter’s Kill

  10. Observations up to the Lake • We observed evidence of the Wooly Adelgid and elongate hemlock scale on Hemlocks and many dead Hemlock trees. • We identified trees, fern and moss life cycle stages and observed primary and secondary succession. The Sunset Carraige trail

  11. Summary of Observations on Oct. 28, 2010 • Color of Lake– Black/green • Temperature – 12.5 oC • Conductivity – 33 uS • Visibility – 3m • pH of Lake– 6.5 • Dissolved Oxygen – 9.2mg/L • Nitrates – 0ppm • Phosphates – 0ppm • Presence of tannins – No • Presence of animal life – Salamanders and fish Lake Minnewaska

  12. Visibility measured with a Sechhi Disc = 3m Lake Minnewaska

  13. Temperature and conductivity– using a YSI temp/salinity/conductivity probe = 12.5oC and 33uS all the way to the bottom (16m) Indicates fall turnover. Lake Minnewaska

  14. pH of Lake using a Pasco pH meter calibrated with 3 test buffers (accuracy +/- 0.2) = 6.5 Lake Minnewaska

  15. Dissolved Oxygen using LaMotte test kits (modified Winkler titration) = 9.2 mg/l Lake Minnewaska

  16. Nitrate and Phosphates using Lamotte test kits = 0ppm Lake Minnewaska

  17. Presence of tannins – no • Presence of animal life – yes, we saw lots of fish (golden shiners) and a salamander Lake Minnewaska
