This waterbody in one line
Perch (Wolctt), a lake in Vermont, is assessed as fully supporting its designated uses, with no impairment causes listed in the state's most recent Integrated Report cycle (2015). By assessed acreage it sits among the smaller assessed lakes nationally (38,628 lakes with a filed area); its impairment list is shorter than on half of assessed lakes (0 listed causes). Aquatic life is assessed as fully 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.
Where Perch (Wolctt) 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.
Small assessed unit
7 acres puts Perch (Wolctt) 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.
Every ruled-on use is fully supporting
The filed use determinations for fish consumption, 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.
IR category in the supporting band
EPA's Integrated Report category for Perch (Wolctt) is 2. 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.
Overall status: fully supporting
Overall status is Fully Supporting. If an IR category or cause row still appears, it usually reflects a prior listing path or a use the overall rollup does not collapse, read those sections rather than stopping at the tile.
According to the U.S. Environmental Protection Agency's ATTAINS program, Vermont carries 712 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Perch (Wolctt) without modification.

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.

| Aquatic Habitat to Support Aquatic Biota, Wildlife, or Plant Life | Aquatic-life or related | Fully Supporting |
| Fish Consumption | Fish-consumption or fishery | Fully Supporting |
| The Use of Waters for Boating and Related Recreational Uses | Recreation | Fully Supporting |
| The Use of Waters for Fishing and Related Recreational Uses | Recreation | Fully Supporting |
| The Use of Waters for Swimming and Other Primary Contact Recreation | Recreation | Fully Supporting |
| The Use of Waters for the Enjoyment of Aesthetic Conditions | Other | Fully Supporting |
| The Use of Water for Irrigation of Crops and Other Agricultural Uses | Other | Not Assessed |
| The Use of the Water for Public Water Source | Drinking-water supply designation | Not Assessed |

Reading the record
Perch (Wolctt): Category 2 reading
2 Category 2: some uses supported, others not assessed
Vermont filed this assessment unit as Category 2: some designated uses are supported and others were not assessed in this cycle. Absence of a failing verdict is not the same as a full Category 1 finding.
Scale and rank
Perch (Wolctt) is one of 712 lake-type waterbodies reported to EPA from Vermont, and one of 712 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 7.00 assessed acres it ranks 33,083rd 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 33,082 lakes with a larger one.
What this record holds
Vermont 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.
Reported trophic class
Vermont carried the trophic field for this assessment unit and filed it as unclassified, which records that no class was determined rather than that the water is unenriched. What the trophic scale measures.

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

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 VT07-19L02. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
