The Peter’s Kill and Lake Minnewaska
Arlington High School Field Trip Data
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.
The Peter’s Kill
Summary of Observations on Oct. 28, 2010
Color of creek – Golden yellowTemperature – 9.5 oCConductivity – 28 uSVisibility – to the bottom (.25m)pH of creek – 4.7Dissolved Oxygen – 9.2mg/LNitrates – 0ppmPhosphates – 0ppmPresence of tannins – YesPresence of animal life - No
Peter’s Kill
Visibility measured with a Sechhi Disc = .25 m (to bottom)
Peter’s Kill
Temperature and conductivity– using a YSI temp/salinity/conductivity probe = 9.5oC, 28 uS
Peter’s Kill
pH of Creek using a Pasco pH meter calibrated with 3 test buffers (accuracy +/- 0.2) = 4.7
Peter’s Kill
Dissolved Oxygen using LaMotte test kits (modified Winkler titration) = 9.2 mg/l
Peter’s Kill
Nitrate and Phosphates using Lamotte test kits = 0ppm

Presence of tannins = yesPresence of animal life = no
The Sunset Carraige trail
Observations up to the LakeWe 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.
Lake Minnewaska

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