Weekly stream samples have been collected from the Arbutus Lake Inlet and Outlet since 1995.  Previously, samples were collected from the Arbutus Lake Outlet only (1983-1994). When the weekly collection is made, two replicate samples are taken from each site. Following collection, samples are kept cold and mailed to the Biogeochemistry Laboratory at SUNY-ESF, where laboratory analyses are performed. Data produced from these analyses include: pH, DOC, NO-3, Cl-, SO2-4, NH+4, total dissolved N, Na+, K+, Mg2+, Ca2+, total Al and silicon.

Note: The archival chemistry data are provided on a daily basis. This is done by interpolating weekly sample data between sampling dates.

1999 - 2007: The stage height at the Arbutus Lake Inlet and Outlet has been continuously measured with a pressure transducer, and recorded by a Campbell Scientific, Inc. datalogger from 1999-2007. During this period, data were downloaded weekly, by AEC staff, and emailed to SUNY-ESF.

2007 - Present: With the establishment of the wireless data network at the Huntington Wildlife Forest, data are downloaded from the Arbutus Inlet and Outlet sites automatically by a server at SUNY-ESF. In addition, data are also downloaded from many other sites at the HWF (Goodnow Mountain Fire Tower, Stream 14, Stream 15, Ackerman Clearing Tower, Groundwater Wells 12, 33, 34, 35 & 36).

In 2007, we began measuring air temperature at the fire tower on Goodnow Mountain.  A meteorological station was also established in the upper Arbutus Watershed, and at the Ackerman Clearing site.
