At a TSI of 67, Elysian (Upper Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Within the 6 graded lakes of Waseca County, Elysian (Upper Lake sits at rank 5, near the bottom of the county list.
