This waterbody in one line

Laurelhurst Pond, a reservoir in Oregon, is assessed as not supporting one or more designated uses, with one listed impairment cause in the state's most recent Integrated Report cycle (2010). 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). Oregon assesses fishing as not supported; it reported no verdict on fish consumption itself.

Laurelhurst 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.

How Laurelhurst Pond 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: in-state cause rank

Inside Oregon, this unit sits toward the short-list end: cause-list rank 163 of 167 indexed units.

Every filed use falls short

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

Laurelhurst Pond: Category 5, TMDL still owed

Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Laurelhurst Pond. 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

5.4 acres puts Laurelhurst Pond 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.

Small within Oregon

State size rank 165 of 167 puts Laurelhurst Pond toward the small end of Oregon's indexed lake-type units with an area.

According to the U.S. Environmental Protection Agency's ATTAINS program, Oregon carries 1,431 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Laurelhurst Pond without modification.

Where Laurelhurst Pond sits among peers

46% of Oregon's lakes assessed this deeply also had no use supported

Oregon ruled definitively on 5 designated uses at Laurelhurst Pond and found none of them supported. The dataset shows 68 Oregon lakes judged to that same depth.

Oregon's assessed lakes are most often judged on 5 or more uses, as this one was.

Scale and rank

Laurelhurst Pond is one of 1,431 lake-type waterbodies reported to EPA from Oregon, and one of 167 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 5.41 assessed acres it ranks 34,225th 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 34,224 lakes with a larger one.

Still unfiled

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

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. 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 OR_LK_1709001202_02_107245. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
