The record
Listed impairment causes
The state reported this reservoir in its 2022 Integrated Report cycle but reached no assessment determination, so no causes are listed. The unit is recorded under EPA integrated-reporting Category 3: reviewed, with insufficient information to determine whether it meets water-quality standards. An undetermined waterbody is neither confirmed clean nor confirmed impaired.

What Swift Creek (Lake Benson)'s record holds
Scale and rank
Swift Creek (Lake Benson) is one of 299 lake-type waterbodies reported to EPA from North Carolina. It is not among the 92 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 472 assessed acres it ranks 3,864th 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 3,863 lakes with a larger one.
What this record holds
North Carolina filed this reservoir in its 2022 Integrated Report cycle but reached no determination, so the record holds that filing and its use rows, but no verdict, and with nothing judged, no impairment cause to track over time. The state has not yet filed a definitive fish-consumption verdict, a definitive recreation verdict, a definitive aquatic-life verdict, and 1 other for this record; those fields populate when it reports them in a future Integrated Report cycle.

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 NC27-43-(5.5)b. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
