This waterbody in one line
Lake Miccosukee, a lake in Florida, is assessed as not supporting one or more designated uses, with 2 listed impairment causes in the state's most recent Integrated Report cycle (2024). By assessed acreage it sits among the largest 5% by assessed acreage nationally (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. Fish consumption is assessed as fully 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 Lake Miccosukee'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: assessed size
The number that most separates Lake Miccosukee nationally is assessed size: 5,007 acres, larger than 98% of the 38,628 lake-type units with an area on file.
The uses disagree
This record splits: Not Supporting on aquatic life, Fully Supporting on fish consumption, recreation. The divergence is inside the designated-use matrix, not a single all-or-nothing label.
Lake Miccosukee: Category 4C reading
Category 4C marks impairment from pollution that is not a pollutant (for example habitat or flow alteration) on Lake Miccosukee. A classic TMDL load model often does not apply; the cause list should name the non-pollutant stressor.
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.
Overall status: not supporting
The filer's overall status for Lake Miccosukee is Not Supporting. That tile summarizes the assessment unit; the designated-use rows and cause list are the evidence behind it.
According to the U.S. Environmental Protection Agency's ATTAINS program, Florida carries 1,475 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Lake Miccosukee 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.
| Designated use | Group | Verdict |
|---|---|---|
| Fish Consumption | Fish-consumption or fishery | Fully Supporting |
| Fish and Wildlife Propagation - Freshwater | Aquatic-life or related | Not Supporting |
| Recreation | Recreation | Fully Supporting |
The record
Listed impairment causes
Causes the state listed as impairing designated uses of this lake, with the cycle each was first listed. None is a pollutant, so none carries a TMDL cleanup plan.
| Cause | Affected uses | First listed | Cleanup standing |
|---|---|---|---|
| Alkalinity | Fish and Wildlife Propagation - Freshwater | Not reported | Not applicable (non-pollutant) |
| pH | Fish and Wildlife Propagation - Freshwater | Not reported | Not applicable (non-pollutant) |
Reading the record
Lake Miccosukee: Category 4C reading
4C Category 4C: impaired by a non-pollutant; TMDL programme does not apply
Florida filed this assessment unit as Category 4C: the impairment is not caused by a pollutant, so the Clean Water Act 303(d) cleanup-plan (TMDL) programme, which allocates pollutant loads, does not apply here.
A 4C listing is still an impairment finding about designated uses; it is not a clean bill of health. How listing and cleanup work.
Scale and rank
Lake Miccosukee is one of 1,475 lake-type waterbodies reported to EPA from Florida, and one of 973 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 5,007 assessed acres it ranks 618th 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 617 lakes with a larger one.
Why no water-level record
Lake Miccosukee has no daily USGS water-level or reservoir-storage series on this page because NWIS lists a lake monitoring site named for the waterbody, but the site is not active, and PlainLakes ingests only the active inventory, so there is no series to attach. How PlainLakes links gauges.

In context
Florida context
ATTAINS carries 1,475 lake-type waterbodies in Florida, 636 assessed as not supporting at least one use and 367 fully supporting. Among the 973 indexed units there, Lake Miccosukee ranks 223rd by listed-cause count (2 listed causes) and 39th by assessed size among the 973 with an area filed; it sits in the not-supporting set (636 statewide) . Its listed causes (Alkalinity and pH) sit outside Florida's top-five list, which is led by Phosphorus, Total.

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 FL791N. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS. See our editorial standards & corrections policy, the methodology behind these numbers, or report a data error. Data current as of 2026-08-17.
