Assessment verdicts are the state agency's decisions as reported to EPA ATTAINS; PlainLakes renders them without modification.
Where Dry 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
The number that most separates Dry Lake nationally is assessed size: 5,432 acres, larger than 99% of the 38,628 lake-type units with an area on file.
According to the U.S. Environmental Protection Agency's ATTAINS program, North Dakota carries 340 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Dry Lake 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 Dry Lake's record holds
Scale and rank
Dry Lake is one of 340 lake-type waterbodies reported to EPA from North Dakota. It is not among the 174 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 5,432 assessed acres it ranks 579th 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 578 lakes with a larger one.
Which uses were judged
North Dakota filed no use-level rows for this lake and reached no overall verdict, so nothing here was judged either way.
What this record holds
North Dakota 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.
Why no water-level record
Dry Lake has no daily USGS water-level or reservoir-storage series on this page because a site carries the lake’s name, but that name fits more than one assessed waterbody in the state, and PlainLakes declines it rather than guessing. How PlainLakes links gauges.

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 ND-09020201-014-L_00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
