This waterbody in one line

Fanny Lake, 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 above 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.

Fanny Lake

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 Fanny 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: cause-list length

The standout filed fact is cause-list length: 2 listed impairment causes, a longer list than 80% of assessed lake-type units (n=23,610). List length tracks how states sample and code, not a severity score.

Not one verdict, several

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.

Fanny Lake: Category 4C reading

Category 4C marks impairment from pollution that is not a pollutant (for example habitat or flow alteration) on Fanny Lake. A classic TMDL load model often does not apply; the cause list should name the non-pollutant stressor.

Overall status: not supporting

The filer's overall status for Fanny Lake is Not Supporting. That tile summarizes the assessment unit; the designated-use rows and cause list are the evidence behind it.

Large assessed unit

At 97.4 acres, Fanny Lake clears the upper tercile of assessed lake-type units with an area on file (11,902 still larger). Size comparisons use the portal's deduplicated lake ranking population, not raw ATTAINS row counts.

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 Fanny Lake without modification. See our methodology for reporting-unit limits and gauge linking rules.

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

Fanny Lake: 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

Fanny Lake 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 97 assessed acres it ranks 11,903rd 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 11,902 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.

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, Fanny Lake ranks 290th by listed-cause count (2 listed causes) and 470th 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 FL2732X. 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.
