Lakes – Cisco Refuge

This data layer shows Minnesota's Cisco Refuge Lakes. They were identified by the University of Minnesota and Minnesota Department of Natural Resources as being deep and clear enough that they will still provide suitable coldwater fish habitat even after significant climate warming. Cisco refuge lakes are classified as Tier 1 (the deepest and coldest with exceptional coldwater fish habitat - predicted TDO3<11 degrees C) and Tier 2 (less deep and cold, but still suitable coldwater habitat - predicted TDO3>11 and <17 degrees C).
