Adirondack Lakes Long Term Monitoring (NY), 1992-2011

This data release represents raw values through final quality assurance. Eight of the original 17 ALTM lake sampling sites established by Syracuse University in 1982 were located some distance downstream from the main lakes usually in proximity to a road. These sites included: Black Pond, Bubb Lake, Cascade Lake, Constable Lake, Otter Lake, Squash Pond, West Pond and Windfall Pond. In 1993, the expanded ALTM project began to collect additional samples upstream of the original roadside sites at the main lake outlets. The ALTM lakes are sampled monthly. Lakes with no outlets and those accessed by helicopter are sampled at the deepest part of hte lake at a depth of 0.5 m with a Kemmerer sampler. All other sites are sampled at the outlet by surface grab method. Samples are analyzed at the ALSC laboratory in Ray Brook, NY. There are 4 lakes with recent liming histories: 030172 Little Clear; 040576 Woods; 040905 Barnes and 060182 Little Simon.
