This waterbody in one line
Woodstock Pond, a reservoir in Virginia, is assessed as not supporting one or more designated uses, with one listed impairment cause in the state's most recent Integrated Report cycle (2026), a cycle that is open for public comment. By assessed acreage it sits among the smaller assessed lakes nationally (38,628 lakes with a filed area); its impairment list is among the longest nationally (one listed cause vs 23,610 assessed lakes).

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.
Reading Woodstock Pond'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: in-state cause rank
Inside Virginia, this unit sits toward the short-list end: cause-list rank 181 of 193 indexed units.
Every filed use falls short
On the uses this filer ruled on, recreation, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.
Woodstock Pond: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Woodstock Pond. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Small assessed unit
7.6 acres puts Woodstock Pond 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.
Small within Virginia
State size rank 193 of 193 puts Woodstock Pond toward the small end of Virginia's indexed lake-type units with an area.
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 Woodstock Pond 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 one definitive verdict 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 |
|---|---|---|
| Recreation | Recreation | Not Supporting Filer confidence: Good |
| Aquatic Life | Aquatic-life or related | Not Assessed |
| Fish Consumption | Fish-consumption or fishery | Not Assessed |
| Wildlife | Other | Not Assessed |
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 |
|---|---|---|---|
| Harmful Algal Blooms | Recreation | 2022 | 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.

Where Woodstock Pond sits among peers
87% of Virginia's lakes assessed this deeply also had no use supported
Virginia ruled definitively on a single designated use at Woodstock Pond and found it not supported. The dataset shows 52 Virginia lakes judged to that same depth.
Virginia's assessed lakes are most often judged on 3 uses; this one was judged on 1.

Scale and rank
Woodstock Pond 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 7.57 assessed acres it ranks 32,780th 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 32,779 lakes with a larger one.
Awaiting a filing
The state has not yet filed a definitive fish-consumption verdict and a definitive aquatic-life verdict for this record; those fields populate when it reports them 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, Woodstock Pond ranks 181st by listed-cause count (one listed cause) and 193rd by assessed size among the 193 with an area filed; it sits in the not-supporting set (181 statewide) . Its listed causes (Harmful Algal Blooms) sit outside Virginia's top-five list, which is led by PCBs in Fish Tissue.

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 VAT-F26L_WSP01A22. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
