This waterbody in one line

Kelly Creek (Lay Lake), a reservoir embayment in Alabama, is assessed as not supporting one or more designated uses, with 5 listed impairment causes 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 (5 listed causes vs 23,610 assessed lakes). Aquatic life is assessed as not supporting. Alabama assesses fishing as not supported; it reported no verdict on fish consumption itself.

Kelly Creek (Lay Lake)

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 Kelly Creek (Lay 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: in-state cause rank

Inside Alabama, cause-list rank is the local separator: Kelly Creek (Lay Lake) is 4 of 263 indexed units by listed-cause count, toward the top of that state's filed lists.

Longer than most cause lists

5 listed causes puts this unit above 97% 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.

No ruled-on use clears the bar

On the uses this filer ruled on, fish consumption, recreation, aquatic life, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.

Kelly Creek (Lay Lake): Category 5, TMDL still owed

Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Kelly Creek (Lay Lake). 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

6.5 acres puts Kelly Creek (Lay Lake) 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.

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 Kelly Creek (Lay Lake) without modification. See our methodology for reporting-unit limits and gauge linking rules.

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 embayment. 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 AL03150106-0808-111. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
