Both Lake St. Croix and St. Croix 1.5 Mi. Upstream of Point Douglas Dr Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — Lake St. Croix (B) versus St. Croix 1.5 Mi. Upstream of Point Douglas Dr Lake (C). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
