Minnesota Valley State Recreation Area

Minnesota Valley State Recreation Area is a Minnesota State Recreation Area — a public-land designation focused on recreation rather than ecological preservation. an unrecorded acreage acres are protected. The park is paired with 8 measured lakes nearby, enough for a multi-lake visit; each lake page carries its own clarity, phosphorus and algae readings.

Reading the per-lake measurements alongside the park designation gives a fuller picture than either alone: the park tells you what land is protected, the readings tell you what condition the water in that protected area is in.
