Cadjaw Pond-02040103000900, a reservoir in Pennsylvania, is assessed as not supporting one or more designated uses, with one listed impairment cause in the state's most recent Integrated Report cycle (2012). By assessed acreage it sits above the national median by assessed acreage (38,628 lakes); its impairment list is among the longest nationally (one listed cause vs 23,610 assessed lakes). Aquatic life is assessed as fully supporting. Pennsylvania assesses fishing as supported; it reported no verdict on fish consumption itself.

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.
How Cadjaw Pond-02040103000900 reads against 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: assessed size
The number that most separates Cadjaw Pond-02040103000900 nationally is assessed size: 87 acres, larger than 67% of the 38,628 lake-type units with an area on file.
Not one verdict, several
This record splits: Not Supporting on recreation, Fully Supporting on fish consumption, aquatic life. The divergence is inside the designated-use matrix, not a single all-or-nothing label.
Cadjaw Pond-02040103000900: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Cadjaw Pond-02040103000900. 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

Reading the record
Cleanup queue for Cadjaw Pond-02040103000900
1 listed cause ranked High in the TMDL queue, still without a plan
Pennsylvania ranked Nutrients high in its TMDL development queue, and no cleanup plan is on file for that listing yet. That queue rank is the state's own scheduling signal, not an EPA national rule.
A High ranking names a position in the state's plan-writing queue; it is not a measure of how impaired the water is. How listing and cleanup work.
Scale and rank
Cadjaw Pond-02040103000900 is one of 516 lake-type waterbodies reported to EPA from Pennsylvania, and one of 246 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 87 assessed acres it ranks 12,794th 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 12,793 lakes with a larger one.
Reported trophic class
Mesotrophic is the trophic class the filing agency reported to EPA ATTAINS for this assessment unit. It describes nutrient enrichment, not whether the water is safe, and it is not a PlainLakes inference. 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
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-02040103000900. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
