Lakes are classified by thermal mixing regimes, with shallow waterbodies historically categorized as continuously mixing systems. Yet, recent studies demonstrate extended summertime stratification in ponds, underscoring the need to reassess thermal classifications for shallow waterbodies. To evaluate the mixing regimes of shallow waters, we measured summertime thermal dynamics in 34 ponds and shallow lakes across temperate North America and Europe. This dataset provides a time series dataset of water temperatures across the water column along with characteristics of each study waterbody, including some physical, chemical, and biological parameters. This dataset accompanies a manuscript entitled "Classifying mixing regimes in ponds and shallow lakes," published in Water Resources Research (10.1029/2022WR032522).
