The North Temperate Lakes Long-Term Ecological Research (NTL-LTER) program conducts and facilitates long term ecological research on Wisconsin lakes. Housed on both the UW-Madison campus and at Trout Lake Station, NTL is part of the larger LTER network funded by the U.S. National Science Foundation since 1981. NTL is committed to promoting and valuing diversity, equity, inclusion, and justice in all aspects of our research and activities. We invite you to explore our datasets and collaborate with us.

Sixteen projects chosen for Research Forward (Round 3) awards
LakeView is an integrated UW lake observatory whose mission is to prepare the scientific community for the next generation of space-based Earth observatories for water quality. NASA missions, scheduled to launch in the next 1-5 years, will generate a new kind of data (hyperspectral imagery) in support of sustainable use of Earth’s natural resources, including lakes.
