This waterbody in one line
Lucile Lake (stormwater outfalls), a lake in Alaska, is assessed as not supporting one or more designated uses, with 3 listed impairment causes in the state's most recent Integrated Report cycle (2020). By assessed acreage it sits among the smaller assessed lakes nationally (38,628 lakes with a filed area); its impairment list is among the longest nationally (3 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.
How Lucile Lake (stormwater outfalls) reads against 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: monitoring lag
The signature tension is currency: the reporting cycle is 2020 while monitoring evidence runs through 2013, a 7-year gap. Cycle year and last-monitored year move independently in ATTAINS; this page shows both.
A split ruling across uses
This record splits: Not Supporting on aquatic life, Fully Supporting on recreation. The divergence is inside the designated-use matrix, not a single all-or-nothing label.
Longer than most cause lists
3 listed causes puts this unit above 90% 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.
Lucile Lake (stormwater outfalls): Category 4A reading
Category 4A means a TMDL (or equivalent) is already approved for the impairment on Lucile Lake (stormwater outfalls). The remaining work is implementation and tracking, read the cleanup-standing and cause rows for what the state already committed to address.
Small assessed unit
5.8 acres puts Lucile Lake (stormwater outfalls) in the lower tercile by assessed area. Small units are often beaches, ponds, or segments, read the water-type and co-filed notes before comparing them to a multi-thousand-acre reservoir.
According to the U.S. Environmental Protection Agency's ATTAINS program, Alaska carries 77 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Lucile Lake (stormwater outfalls) 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. The latest monitoring Alaska filed against this record runs through 2013. For the definitive verdicts on this record, Alaska filed the assessment basis as Monitored & Extrapolated Data. Those are EPA's own words, not PlainLakes' summary of them; where a verdict is filed as extrapolated, the state did not reach it from monitoring alone.
| Designated use | Group | Verdict |
|---|---|---|
| Fresh Water / Growth and Propagation of Fish, Shellfish, Other Aquatic Life and Wildlife | Aquatic-life or related | Not Supporting |
| Fresh Water / Water Recreation / Contact Recreation | Recreation | Fully Supporting |
| Fresh Water / Water Recreation / Secondary Recreation | Recreation | Fully Supporting |
| Fresh Water / Water Supply / Agriculture, Including Irrigation and Stock Watering | Other | Fully Supporting |
| Fresh Water / Water Supply / Aquaculture | Other | Not Supporting |
| Fresh Water / Water Supply / Drinking, Culinary, and Food Processing | Drinking-water supply designation | Fully Supporting |
| Fresh Water / Water Supply / Industrial | Other | Fully Supporting |

Reading the record
Lucile Lake (stormwater outfalls): Category 4A reading
4A Category 4A: impaired, TMDL completed
Alaska filed this assessment unit as Category 4A: impaired, with a pollutant-budget TMDL already completed under 303(d). The listing remains an impairment finding; the plan is on file rather than still awaiting write-up.
Scale and rank
Lucile Lake (stormwater outfalls) is one of 77 lake-type waterbodies reported to EPA from Alaska, and one of 12 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 5.77 assessed acres it ranks 34,047th 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 34,046 lakes with a larger one.
Awaiting a filing
The state has not yet filed a definitive fish-consumption verdict for this record; that field populates when it reports it 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 AK_L_2040105_036_001. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
