This waterbody in one line
Pike Lake, a lake in Indiana, is assessed as not supporting one or more designated uses, with 2 listed impairment causes in the state's most recent Integrated Report cycle (2008). By assessed acreage it sits in the upper quartile by assessed acreage nationally (38,628 lakes); its impairment list is among the longest nationally (2 listed causes vs 23,610 assessed lakes). Indiana assesses human health and wildlife as not supported; it reported no verdict on fish consumption itself. A USGS gauge tracks its gage height daily.

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.
Pike Lake against the ATTAINS 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 Indiana, cause-list rank is the local separator: Pike Lake is 20 of 162 indexed units by listed-cause count, toward the top of that state's filed lists.
Every ruled-on use is not supporting
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.
Pike Lake: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Pike Lake. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Large assessed unit
At 203 acres, Pike Lake clears the upper tercile of assessed lake-type units with an area on file (7,121 still larger). Size comparisons use the portal's deduplicated lake ranking population, not raw ATTAINS row counts.
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.
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 Pike Lake 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. Indiana filed its own confidence on the 2 definitive verdicts it rated: Good and Excellent. 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 |
|---|---|---|
| Full Body Contact | Recreation | Not Supporting Filer confidence: Excellent |
| Human Health and Wildlife | Fish-consumption or fishery | Not Supporting Filer confidence: Good |
| Warm Water Aquatic Life | Aquatic-life or related | Not Assessed |

Listed impairment causes
Causes the state listed as impairing designated uses of this lake, with the cycle each was first listed and the Clean Water Act action recorded against it.
| Cause | Affected uses | First listed | Cleanup standing |
|---|---|---|---|
| PCBs in Fish Tissue | Human Health and Wildlife | 2006 | TMDL priority: Low |
| Phosphorus, Total | Full Body Contact | 2006 | TMDL priority: Medium |

Where Pike Lake sits among peers
22% of Indiana's lakes assessed this deeply also had no use supported
Indiana ruled definitively on 2 designated uses at Pike Lake and found none of them supported. The dataset shows 69 Indiana lakes judged to that same depth.
Indiana's assessed lakes are most often judged on 1 use; this one was judged on 2.

Scale and rank
Pike Lake is one of 1,588 lake-type waterbodies reported to EPA from Indiana, and one of 162 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 203 assessed acres it ranks 7,122nd 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 7,121 lakes with a larger one.
Water level
A USGS gauge tracks this lake's gage height daily, and the latest reading is 0.12 ft above the reading 30 days earlier, against a 365-day observed range of 4.0 ft. 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.
Water level: 365-day record
Daily gage height values, feet above this gauge’s own local zero, not above sea level, from USGS gauge 03331040 (Pike Lake at Warsaw, in), shown weekly. Readings are daily-batch snapshots, not real-time conditions. Each daily value is a single reading taken at 24:00, not a daily mean. It is the only daily statistic USGS files for this gauge.

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
- Water levels shown are daily snapshots. Seasonal drawdown and datum conventions matter when comparing levels. How to read level data
- 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 INB06P1005_00. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
