Decades of water column temperature, lake level and meteorological data of Lake Lacawac, a pristine glacial lake at Lacawac Biological Field Station in the Pocono mountains, Pennsylvania USA (1992-2019)

Lake Lacawac weather and the lake water column were monitored to
observe seasonal and interannual temperature and lake level patterns
in response to solar heating, wind-driven water column mixing,
precipitation, evaporation, watershed runoff and seepage, and outflow
(L. Lacawac has an outflow stream but no inflow stream, and is
surrounded on one side by peat bogs). Several studies have shown the
lake to have a slow exchange by seepage (slightly more seeping in than
out except during dry months). Over the years the raft data have been
used to calibrate heat flux, mixing, and evaporation models for the
lake, to study zooplankton and phytoplankton distribution and
dissolved organic matter flux (photobleaching in the water column,
influx from the watershed, and exchange with bottom sediments) and
associated UV transparency. The data have also been used to accompany
experimental manipulations of lake organisms (algae, zooplankton,
fish) in relation to exposure to UV radiation. More recently these
lake data have been useful in developing lake indices of climate
change.
