This waterbody in one line
Eagle Creek Reservoir (Pws), a lake in Indiana, is assessed as not supporting one or more designated uses, with 3 listed impairment causes in the state's most recent Integrated Report cycle (2026). By assessed acreage it sits among the largest 5% by assessed acreage nationally (38,628 lakes); its impairment list is among the longest nationally (3 listed causes vs 23,610 assessed lakes). Aquatic life is assessed as not supporting. Indiana assesses human health and wildlife as not 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.
Reading Eagle Creek Reservoir (Pws)'s filed record
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 Indiana, cause-list rank is the local separator: Eagle Creek Reservoir (Pws) is 3 of 162 indexed units by listed-cause count, toward the top of that state's filed lists.
Large assessed unit
At 1,350 acres, Eagle Creek Reservoir (Pws) clears the upper tercile of assessed lake-type units with an area on file (1,836 still larger). Size comparisons use the portal's deduplicated lake ranking population, not raw ATTAINS row counts.
Every filed use falls short
On the uses this filer ruled on, fish consumption, aquatic life, every determination is Not Supporting. That is a use-by-use reading of the filed record, not a single overall lake grade.
Longer than most cause lists
3 listed causes puts this unit above 90% 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.
Eagle Creek Reservoir (Pws): Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Eagle Creek Reservoir (Pws). Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
According to the U.S. Environmental Protection Agency's ATTAINS program, Indiana carries 1,588 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Eagle Creek Reservoir (Pws) without modification. See our methodology for reporting-unit limits and gauge linking rules.
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. Indiana filed 2024 as the year this waterbody was last monitored. Indiana filed its own confidence on the one definitive verdict 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.
| Designated use | Group | Verdict |
|---|---|---|
| Human Health and Wildlife | Fish-consumption or fishery | Not Supporting Filer confidence: Good |
| Public Water Supply | Drinking-water supply designation | Not Supporting |
| Warm Water Aquatic Life | Aquatic-life or related | Not Supporting |
| Full Body Contact | Recreation | Not Assessed |

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 lake. 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 INW01P1069_00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
