This waterbody in one line

Puzzle 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 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 not supporting.

Puzzle 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.

How Puzzle Lake 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: assessed size

The number that most separates Puzzle Lake nationally is assessed size: 1,770 acres, larger than 96% of the 38,628 lake-type units with an area on file.

No ruled-on use clears the bar

On the uses this filer ruled on, fish consumption, recreation, aquatic life, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.

Puzzle Lake: Category 5, TMDL still owed

Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Puzzle Lake. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.

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

EPA-established cleanup plan. EPA, not Florida, established the cleanup plan on this record. ATTAINS records the agency responsible for each determination and records EPA's for these; it does not record why. The Clean Water Act provides for EPA to establish a load itself where a state does not submit one, or where EPA disapproves the one it submits.

Scale and rank

Puzzle 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 1,770 assessed acres it ranks 1,497th 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 1,496 lakes with a larger one.

What to do with this record

  • The fish-consumption use is assessed as not supporting. Before eating fish from this lake, check your state fish-advisory program for species-specific meal limits. 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 FL2964B. 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.
