This waterbody in one line
Wahalak Creek (Coffeeville Lake), a reservoir embayment in Alabama, is assessed as not supporting one or more designated uses, with one listed impairment cause in the state's most recent Integrated Report cycle (2022). 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). Aquatic life is assessed as fully supporting. Alabama 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.
Where Wahalak Creek (Coffeeville Lake) 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: assessed size
What stands out first is how small the assessed unit is: 4.9 acres, smaller than 90% of the 38,628 lake-type units carrying an area.
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.
Wahalak Creek (Coffeeville Lake): Category 4A reading
Category 4A means a TMDL (or equivalent) is already approved for the impairment on Wahalak Creek (Coffeeville Lake). The remaining work is implementation and tracking, read the cleanup-standing and cause rows for what the state already committed to address.
Overall status: not supporting
The filer's overall status for Wahalak Creek (Coffeeville Lake) is Not Supporting. That tile summarizes the assessment unit; the designated-use rows and cause list are the evidence behind it.
Typical cause-list length
1 listed cause is a middle-tercile list length among assessed lake-type units. Look to IR category and use outcomes for the distinctive reading.
According to the U.S. Environmental Protection Agency's ATTAINS program, Alabama carries 304 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Wahalak Creek (Coffeeville Lake) without modification.

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 AL03160201-0904-111. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
