NTL site information

North Temperate Lakes

The NTL catchment we will be focusing on contains ten large lakes and numerous small bogs, ponds and streams.
Five lakes are NTL LTER study lakes: Trout Lake, Crystal Lake, Big Muskellunge Lake, Allagash Lake, and Sparkling Lake. The LTER also studies two bog lakes: Crystal Bog and Trout Bog.
Five lakes are not LTER study lakes: Mann Lake, Pallette Lake, Lost Canoe Lake, Escanaba Lake, and Little John Lake.

Lake Levels

Some of the lakes are solely fed by groundwater and direct precipitation (Sparkling, Crystal), some are headwater lakes (Big Musky), and others are flowthrough lakes (Trout). Lake levels of the LTER study lakes show long term trends in lake level. The overall range is ~0.5 m.
