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 Hospital Lake nationally is assessed size: 480 acres, larger than 90% of the 38,628 lake-type units with an area on file.
IR category 3 on Hospital Lake
The Integrated Report category filed for Hospital Lake is 3. PlainLakes renders EPA's code without remapping it into a consumer grade.

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.

The record
Listed impairment causes
The state reported this lake in its 2004 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 Hospital Lake's record holds
Scale and rank
Hospital Lake is one of 77 lake-type waterbodies reported to EPA from Alaska. It is not among the 12 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 480 assessed acres it ranks 3,827th 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 3,826 lakes with a larger one.
What this record holds
Alaska filed this lake in its 2004 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.
Reported trophic class
Alaska carried the trophic field for this assessment unit and filed it as unclassified, which records that no class was determined rather than that the water is unenriched. What the trophic scale measures.

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 AK_L_7050621_002. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
