This waterbody in one line

Independence, a lake in Minnesota, is assessed as not supporting one or more designated uses, with one listed impairment cause in the state's most recent Integrated Report cycle (2020). By assessed acreage it sits above the national median by assessed acreage (38,628 lakes); its impairment list is among the longest nationally (one listed cause vs 23,610 assessed lakes). Fish consumption is assessed as not supporting.

Independence

A composite of this record's EPA ATTAINS designated-use verdicts, filed impairment count, and assessment currency, weighted and benchmarked against the national corpus of assessed active waterbodies. This is a water-quality standing, not a human-recreation or property-value judgment, and dimensions with no filed verdict drop out rather than count against the score.

How Independence reads against the filed register

Paragraphs are selected by this unit's percentiles and use matrix: different lakes lead with different dimensions. Figures are ATTAINS / portal register arithmetic, not advice.

The signature stat: in-state cause rank

Inside Minnesota, cause-list rank 1487 of 1,939 is mid-pack, the state peer table is not driven by an extreme list length here.

Every filed use falls short

On the uses this filer ruled on, fish consumption, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.

Independence: Category 4A reading

Category 4A means a TMDL (or equivalent) is already approved for the impairment on Independence. The remaining work is implementation and tracking, read the cleanup-standing and cause rows for what the state already committed to address.

Overall status: not supporting

The filer's overall status for Independence is Not Supporting. That tile summarizes the assessment unit; the designated-use rows and cause list are the evidence behind it.

Small within Minnesota

State size rank 1608 of 1,930 puts Independence toward the small end of Minnesota's indexed lake-type units with an area.

According to the U.S. Environmental Protection Agency's ATTAINS program, Minnesota carries 13,176 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Independence without modification.

Reading the record

Independence: Category 4A reading

4A Category 4A: impaired, TMDL completed

Minnesota filed this assessment unit as Category 4A: impaired, with a pollutant-budget TMDL already completed under 303(d). The listing remains an impairment finding; the plan is on file rather than still awaiting write-up.

How listing and cleanup work.

Scale and rank

Independence is one of 13,176 lake-type waterbodies reported to EPA from Minnesota, and one of 1,939 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 81 assessed acres it ranks 13,401st by assessed size among the 38,628 lakes the dataset carries an area for, counting a state’s repeated filings of one water once, behind 13,400 lakes with a larger one.

Still unfiled

The state has not yet filed a definitive recreation verdict and a definitive aquatic-life verdict for this record; those fields populate when it reports them in a future Integrated Report cycle.

What to do with this record

  • The fish-consumption use is assessed as not supporting. Before eating fish from this lake, check your state fish-advisory program for species-specific meal limits. Consumption status guide
  • Impairment listings follow the Clean Water Act 303(d) process; a listing is a regulatory finding, not a closure notice. 303(d) explained

PlainLakes renders state assessment decisions and federal gauge observations without modification. It does not issue advisories.

Assessment decisions on this page are rendered directly from state Integrated Report records in EPA's ATTAINS system; gauge figures are daily-value observations from the USGS National Water Information System, no number is typed in by an editor. Overall status, use verdicts, and causes are the state's reported decisions for assessment unit MN32-0017-00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
