Where Jourdain Lake stands in 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: assessed size
What stands out first is how small the assessed unit is: 12.3 acres, smaller than 77% of the 38,628 lake-type units carrying an area.
Overall status: Not Assessed
ATTAINS overall status on this unit is “Not Assessed”. PlainLakes does not rewrite that vocabulary into a consumer score.
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 Jourdain Lake without modification. See our methodology for reporting-unit limits and gauge linking rules.

Listed impairment causes
The Red Lake Band of Chippewa Indians reported this lake in its 2022 Integrated Report cycle but reached no assessment determination, so no causes are listed. An undetermined waterbody is neither confirmed clean nor confirmed impaired.
Reading the record
What Jourdain Lake's record holds
Scale and rank
Jourdain Lake 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 12 assessed acres it ranks 29,863rd 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 29,862 lakes with a larger one.
What this record holds
The Red Lake Band of Chippewa Indians filed this lake in its 2022 Integrated Report cycle but reached no determination, so the record holds that filing and its use rows, but no verdict, and with nothing judged, no impairment cause to track over time. The Red Lake Band of Chippewa Indians 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 Red Lake Band of Chippewa Indians's reported decisions for assessment unit RLN_JOUR. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
