Adirondack Lakes Survey (NY): summer surface chemistry datat, 1984-1987

Reported water chemistry data are from the intensive lake chemistry survey conducted between the months of July and August from 1984 – 1987 as part of the larger Adirondack lakes survey of chemistry and fish. This intensive sampling took place in the summer when most Adirondack waters are typically stratified. When possible, the middle or deepest part of the lake was sampled to avoid the effects of littoral zones and inlet streams. Samples in isothermal waters were collected 1.5 meters below the surface or at mid-depth when the waters were less than 1.5 meters deep. In stratified waters, a sample was collected at 1.5 meters below the surface and also half way between the thermocline and the bottom. Chemical analysis was conducted at the Adirondack Lakes Survey Corporation (ALSC) laboratory in Ray Brook following EPA guidelines.
