The record
Designated-use assessments
Fully Supporting and Not Supporting are the state's definitive verdicts; other entries mean the use was not conclusively assessed in this cycle.
| Designated use | Group | Verdict |

| Marginal Warmwater Aquatic Life | Aquatic-life or related | Not Assessed |
| Primary Contact | Recreation | Not Assessed |
| Wildlife Habitat | Aquatic-life or related | Not Assessed |
The record
Listed impairment causes
The state reported this lake in its 1998 Integrated Report cycle but reached no assessment determination, so no causes are listed. The unit is recorded under EPA integrated-reporting Category 3: reviewed, with insufficient information to determine whether it meets water-quality standards. An undetermined waterbody is neither confirmed clean nor confirmed impaired.
Reading the record
What Laguna Gatuna's record holds
Scale and rank
Laguna Gatuna is one of 176 lake-type waterbodies reported to EPA from New Mexico. It is not among the 58 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 392 assessed acres it ranks 4,423rd 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 4,422 lakes with a larger one.
What this record holds
New Mexico filed this lake in its 1998 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 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 NM-9000.B_055. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
