This waterbody in one line

Red Lake-Anton Road Pond, a lake in Alaska, is assessed as not supporting one or more designated uses, with 2 listed impairment causes in the state's most recent Integrated Report cycle (1994). 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 (2 listed causes vs 23,610 assessed lakes). Aquatic life is assessed as not supporting.

Red Lake-Anton Road Pond

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 Red Lake-Anton Road Pond 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: 0.9 acres, smaller than 98% of the 38,628 lake-type units carrying an area.

Every ruled-on use is not supporting

On the uses this filer ruled on, 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.

Red Lake-Anton Road Pond: Category 4A reading

Category 4A means a TMDL (or equivalent) is already approved for the impairment on Red Lake-Anton Road Pond. The remaining work is implementation and tracking, read the cleanup-standing and cause rows for what the state already committed to address.

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.

Overall status: not supporting

The filer's overall status for Red Lake-Anton Road Pond is Not Supporting. That tile summarizes the assessment unit; the designated-use rows and cause list are the evidence behind it.

According to the U.S. Environmental Protection Agency's ATTAINS program, Alaska carries 77 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Red Lake-Anton Road Pond without modification.

The record

Designated-use assessments

Fully Supporting and Not Supporting are the state's definitive verdicts; other entries mean the use was not conclusively assessed in this cycle. Alaska filed its own confidence on the 7 definitive verdicts it rated: Good. That rating is the filer's, in EPA's own field, and EPA publishes no definition of the four words it offers.

Reading the record

Red Lake-Anton Road Pond: Category 4A reading

4A Category 4A: impaired, TMDL completed

Alaska filed this assessment unit as Category 4A: impaired, with a pollutant-budget TMDL already completed under 303(d). The listing remains an impairment finding; the plan is on file rather than still awaiting write-up.

How listing and cleanup work.

Scale and rank

Red Lake-Anton Road Pond is one of 77 lake-type waterbodies reported to EPA from Alaska, and one of 12 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 0.90 assessed acres it ranks 37,736th 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 37,735 lakes with a larger one.

Awaiting a filing

The state has not yet filed a definitive fish-consumption verdict for this record; that field populates when it reports it in a future Integrated Report cycle.

Reported trophic class

Alaska carried the trophic field for this assessment unit and filed it as unclassified, which records that no class was determined rather than that the water is unenriched. 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 AK_L_2070115_036. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
