This waterbody in one line
Little Crooked Lake, a lake in Florida, is assessed as fully supporting its designated uses, with no impairment causes listed in the state's most recent Integrated Report cycle (2024). By assessed acreage it sits among the largest 10% by assessed acreage nationally (38,628 lakes); its impairment list is shorter than on half of assessed lakes (0 listed causes). Aquatic life 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.
Where Little Crooked Lake stands in 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: cause-list length
The standout filed fact is a short cause list: 0 causes, shorter than 51% of assessed lake-type units. A short list can mean a focused impairment, or a shallow assessment.
Large assessed unit
At 762.4 acres, Little Crooked Lake clears the upper tercile of assessed lake-type units with an area on file (2,762 still larger). Size comparisons use the portal's deduplicated lake ranking population, not raw ATTAINS row counts.
All ruled-on uses pass
The filed use determinations for recreation, aquatic life are all Fully Supporting. Where an overall IR category still flags the unit, look at the cause list and report standing rather than treating the use row as empty.
Large within Florida
Among Florida's 973 indexed units with an area, Little Crooked Lake ranks 133 by assessed size, toward the large end of that state file.
IR category in the supporting band
EPA's Integrated Report category for Little Crooked Lake is 1. In ATTAINS that band means the assessed uses are supporting (or supporting with other waters in the unit), so the narrative weight shifts to how deep the assessment went and whether monitoring is current, not to a restoration plan.
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 Little Crooked Lake without modification.

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 and Wildlife Propagation - Freshwater | Aquatic-life or related | Fully Supporting |
| Recreation | Recreation | Fully Supporting |
The record
Listed impairment causes
The state's reported assessment lists no impairment causes for this lake.
Reading the record
Little Crooked Lake: Category 1 reading
1 Category 1: all designated uses supported
Florida filed this assessment unit as Category 1: every designated use assessed here was reported as supported. That is the filer's Integrated Report classification, not a PlainLakes score.
Scale and rank
Little Crooked 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 762 assessed acres it ranks 2,763rd 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 2,762 lakes with a larger one.
What this record holds
Florida completed an assessment here and listed no impairment cause, so the record holds a verdict and its supporting use rows but no pollutant to track over time. 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 FL1663B. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
