Acadia National Park, U.S. National Park Service using Lakes and Stream Monitoring Protocol for National Parks in the Northeast Temperate Network, Version 1.1 (2006-2011)

Water quality data collected by Acadia National Park (U.S. National Park Service) staff using the procedures found in the Lakes and Stream Monitoring Protocol for National Parks in the Northeast Temperate Network, Version 1.1. Sampling occurs annually and is scheduled to continue indefinitely. Additional data from non-NPS collaborators are also included (in the pre-2006 sheets).

Parameters measured in the field include Secchi transparency and surface temperature. Secchi depth was always measured using a viewing scope with "mask". Color, chlorophyll a, total nitrogen, total phosphorus, DOC, anion & cation samples were collected as grab samples or depth-integrated epilimnetic samples in lakes, and then sent to a central laboratory for analyses. These samples were collected in April, June, August and October. The National Water Quality Lab was used for analysis in 2006 & 2007; the Sawyer Environmental Chemistry Research Lab was used 2008-2011. Values below reporting/detection level indicated in associated "Flag" field. Empty cells with no associated flag indicate no data collected for parameter.
