Reading Lost's filed record
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: assessed size
Assessed size is not the extreme here: 37.2 acres sits near the middle of the 38,628 units with an area filed (percentile 48).
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 Lost without modification. See our methodology for reporting-unit limits and gauge linking rules.
The record
Listed impairment causes
No causes are listed because this lake has no overall assessment verdict in the reported cycle. An unassessed waterbody is neither confirmed clean nor confirmed impaired.
Reading the record
What Lost's record holds
Scale and rank
Lost is one of 13,176 lake-type waterbodies reported to EPA from Minnesota. It is not among the 1,939 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 37 assessed acres it ranks 20,294th 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 20,293 lakes with a larger one.
Which uses were judged
Minnesota filed no use-level rows for this lake and reached no overall verdict, so nothing here was judged either way.
What this record holds
Minnesota filed no overall verdict, no reporting cycle and no EPA category for this lake, so the record holds the identifying fields above and no judgement of any kind: no verdict, and no impairment cause to track over time. The state has not yet filed a definitive fish-consumption verdict, a definitive recreation verdict, a definitive aquatic-life verdict, and 1 other for this record; those fields populate when it reports them in a future Integrated Report cycle.

What to do with this record
- Assessment verdicts are cycle-based, not real-time. For fish-consumption decisions, your state advisory program is the binding source. 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 MN31-0900-00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of 2026-08-17.
