This waterbody in one line
Kingfisher Lakes - Lower Lake, a reservoir in Kentucky, is assessed as not supporting one or more designated uses, with 2 listed impairment causes in the state's most recent Integrated Report cycle (2022). By assessed acreage it sits below the national median by assessed acreage (38,628 lakes); its impairment list is among the longest nationally (2 listed causes vs 23,610 assessed lakes). Aquatic life is assessed as not supporting.

Assessment verdicts are the state agency's decisions as reported to EPA ATTAINS; PlainLakes renders them without modification.
A composite of this record's EPA ATTAINS designated-use verdicts, filed impairment count, and assessment currency, weighted and benchmarked against the national corpus of assessed active waterbodies. This is a water-quality standing, not a human-recreation or property-value judgment, and dimensions with no filed verdict drop out rather than count against the score.
Reading Kingfisher Lakes - Lower Lake's filed record
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: in-state cause rank
Inside Kentucky, cause-list rank is the local separator: Kingfisher Lakes - Lower Lake is 22 of 108 indexed units by listed-cause count, toward the top of that state's filed lists.
No ruled-on use clears the bar
On the uses this filer ruled on, aquatic life, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.
Kingfisher Lakes - Lower Lake: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Kingfisher Lakes - Lower Lake. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Small within Kentucky
State size rank 101 of 108 puts Kingfisher Lakes - Lower Lake toward the small end of Kentucky's indexed lake-type units with an area.
Longer than most cause lists
2 listed causes puts this unit above 80% of assessed lake-type records by list length. Treat that as a coding-and-sampling signal: states that split pollutants finely mint longer lists without proving worse water.
According to the U.S. Environmental Protection Agency's ATTAINS program, Kentucky carries 141 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Kingfisher Lakes - Lower Lake without modification. See our methodology for reporting-unit limits and gauge linking rules.
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.

| Warm Water Aquatic Habitat | Aquatic-life or related | Not Supporting |
| Domestic Water Supply | Drinking-water supply designation | Not Assessed |
| Fish Consumption | Fish-consumption or fishery | Not Assessed |
| Primary Contact Recreation Water | Recreation | Insufficient Information |
| Secondary Contact Recreation Water | Recreation | Insufficient Information |

Scale and rank
Kingfisher Lakes - Lower Lake is one of 141 lake-type waterbodies reported to EPA from Kentucky, and one of 108 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 21 assessed acres it ranks 25,669th 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 25,668 lakes with a larger one.
Open in the register
The state has not yet filed a definitive fish-consumption verdict and a definitive recreation verdict for this record; those fields populate when it reports them in a future Integrated Report cycle.
Reported trophic class
Hypereutrophic is the trophic class the filing agency reported to EPA ATTAINS for this assessment unit. It describes nutrient enrichment, not whether the water is safe, and it is not a PlainLakes inference. 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 KY-1030. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
