A 10‐yr record of the thermal characteristics four lakes at North‐Temperate Lakes Long‐Term Ecological Research site was analyzed and used to validate simulations lake physics with dynamic reservoir simulation model. Simulations cool, warm, intermediate years were rerun meteorology from general circulation models a doubling CO 2 . In all doubled there is an earlier onset stratification, increased summer epilimnetic temperature (1–7°C), intensity longer duration stratification. Maximum surface temperatures times may exceed upper lethal limits warm cool water fish in some scenarios. Suitable habitat for cold water, generally increases scenarios after climate change. Changes vertical migration Daphnia, however, are expected vary depending on interaction stratification use. northern Wisconsin planktivores, overlap between zooplankton decrease, while southern increase. Although most physical responses change consistent among scenarios, biological will likely be more variable owing complex nature factors determining ecological interactions lakes.
