This waterbody in one line
Lake Gordon, a reservoir in Virginia, is assessed as not supporting one or more designated uses, with 2 listed impairment causes in the state's most recent Integrated Report cycle (2026), a cycle that is open for public comment. 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. Fish consumption is assessed as not 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 Lake Gordon 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 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.
No ruled-on use clears the bar
On the uses this filer ruled on, fish consumption, aquatic life, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.
Lake Gordon: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Lake Gordon. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Overall status: not supporting
The filer's overall status for Lake Gordon 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 107.5 acres, Lake Gordon clears the upper tercile of assessed lake-type units with an area on file (11,167 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, Virginia carries 275 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Lake Gordon 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. Virginia filed its own confidence on the 3 definitive verdicts it rated: Good. That rating is the filer's, in EPA's own field, and EPA publishes no definition of the four words it offers.
| Designated use | Group | Verdict |
|---|---|---|
| Aquatic Life | Aquatic-life or related | Not Supporting Filer confidence: Good |
| Fish Consumption | Fish-consumption or fishery | Not Supporting Filer confidence: Good |
| Wildlife | Other | Fully Supporting Filer confidence: Good |
| Public Water Supply | Drinking-water supply designation | Not Assessed |
| Recreation | Recreation | Insufficient Information Filer confidence: Good |
The record
Listed impairment causes
Causes the state listed as impairing designated uses of this reservoir, with the cycle each was first listed and the Clean Water Act action recorded against it.
| Cause | Affected uses | First listed | Cleanup standing |
|---|---|---|---|
| Mercury in Fish Tissue | Fish Consumption | 2010 | TMDL priority: Low |
| Chlorophyll-a | Aquatic Life | 2016 | TMDL priority: Low |
Probable sources
Virginia listed the source of the impairment as unknown. That is the state's own filed value, not a gap in this record: the cause has been identified, the origin has not.
Reading the record
Where Lake Gordon sits among peers
71% of Virginia's lakes assessed this deeply also came out mixed
Virginia ruled definitively on 3 designated uses at Lake Gordon and found 2 of 3 not supported. The dataset shows 93 Virginia lakes judged to that same depth.
Virginia's assessed lakes are most often judged on 3 uses, as this one was.

Scale and rank
Lake Gordon is one of 275 lake-type waterbodies reported to EPA from Virginia, and one of 193 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 107 assessed acres it ranks 11,168th 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 11,167 lakes with a larger one.
Open in the register
The state has not yet filed a definitive recreation verdict for this record; that field populates when it reports it in a future Integrated Report cycle.
Reported trophic class
Virginia 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.

In context
Virginia context
ATTAINS carries 275 lake-type waterbodies in Virginia, 181 assessed as not supporting at least one use and 50 fully supporting. Among the 193 indexed units there, Lake Gordon ranks 76th by listed-cause count (2 listed causes) and 119th by assessed size among the 193 with an area filed; it sits in the not-supporting set (181 statewide) . Its listed causes include Mercury in Fish Tissue, which also appears among Virginia's most-filed impairment causes (led by PCBs in Fish Tissue). It also lists Chlorophyll-a, outside that top-five list.

What to do with this record
- The fish-consumption use is assessed as not supporting. Before eating fish from this reservoir, 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 VAW-L79L_MES01L00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
