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.
Bradys Lake-02040106001139 against the ATTAINS 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: in-state cause rank
Inside Pennsylvania, cause-list rank is the local separator: Bradys Lake-02040106001139 is 31 of 246 indexed units by listed-cause count, toward the top of that state's filed lists.
Mixed use determinations
This record splits: Not Supporting on fish consumption, Fully Supporting on recreation. The divergence is inside the designated-use matrix, not a single all-or-nothing label.
Bradys Lake-02040106001139: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Bradys Lake-02040106001139. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Large assessed unit
At 223.4 acres, Bradys Lake-02040106001139 clears the upper tercile of assessed lake-type units with an area on file (6,617 still larger). Size comparisons use the portal's deduplicated lake ranking population, not raw ATTAINS row counts.
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.
According to the U.S. Environmental Protection Agency's ATTAINS program, Pennsylvania carries 516 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Bradys Lake-02040106001139 without modification.

The record
Assessment entries
Fully Supporting and Not Supporting are the state's definitive verdicts; other entries mean the use was not conclusively assessed in this cycle.
| Assessment entry | Group | Verdict |
|---|---|---|
| Aesthetics | Other | Fully Supporting |
| Boating | Recreation | Fully Supporting |
| Exceptional Value Waters | Other | Not Supporting |
| Fishing | Fish-consumption or fishery | Not Supporting |
| Potable Water Supply | Drinking-water supply designation | Fully Supporting |
Not every entry above is a designated use: Exceptional Value Waters is an antidegradation protection class, not a designated use. The state files it in the ATTAINS use column, so it carries whatever verdict the state recorded against it.

| Mercury | Fishing | 2018 | TMDL priority: Medium |
| pH | Exceptional Value Waters (a protection class, not a use) | 2018 | TMDL priority: Medium |

What to do with this record
- The listing here is on a fishery use, not on fish consumption, and this state reported no consumption verdict for this reservoir. Your state fish-advisory program is the source for whether the catch is safe to eat. 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 PA-LRP-02040106001139. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
