The lake type indicates whether the lake is located above or below treeline, and the Park/Range variable refers to whether the lake is located in Rocky Mountain National Park (RMNP) or the Snowy Range. Max depth refers to the maximum depth recorded in the field and averaged between both early summer (Visit 1) and late summer (Visit 2). The surface temperature was taken at the time of sampling and also averaged between both visits.
