Geochemical data from Little Comfort and Keewahtin Lakes, Minnesota 2023-2024.

Depth profiles of water column chemical and physical properties were assessed with seasonal-scale frequency from Little Comfort from September 2023 to June 2024 and from Keewahtin Lake in September 2023. The data were collected to assess mixing status, major geochemical constituents within the lake, and mineral precipitation reactions. Several parameters were routinely measured with deployable probes at meter or sub-meter resolution at the deepest location in each lake. Water samples were also collected for laboratory analysis.
