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

2. The Peter’s Kill Site 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.

3. The Peter’s Kill 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

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

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

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

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

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

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

10. The Sunset Carraige trail 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.

11. Lake Minnewaska 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

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

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

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

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

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

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