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 Morrison 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 Morrison Lake's record holds
Scale and rank
Morrison 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 2,021 assessed acres it ranks 1,364th 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 1,363 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.
Water level
A USGS gauge tracks this lake's gage height daily, and the latest reading is 1.04 ft below the reading 30 days earlier, against a 365-day observed range of 3.4 ft. 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.
Water level: 365-day record

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
- Water levels shown are daily snapshots. Seasonal drawdown and datum conventions matter when comparing levels. How to read level data
- 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-09020201-023-L_00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
