North Temperate Lakes LTER: Ice Duration - Trout Lake Area
Entry ID: NTL_PH04

[ Update this Record ]

Abstract: Data include day of freeze-up and thaw of seven primary lakes (Allequash, Big
Muskellunge, Crystal, Sparkling, and Trout lakes, and unnamed lakes 27-02 and
12-15 and Little Rock Lake). Observations are made every other day during times
of freeze and thaw. A lake is considered ice covered when the sampling station
(the deepest part of the lake) is ice covered. The lake is considered thawed
when it is possible to drive a boat from the boat landing to the sampling
station without encountering ice.
