This waterbody in one line
Inman Lake, a lake in Kansas, is assessed as not supporting one or more designated uses, with one listed impairment cause in the state's most recent Integrated Report cycle (2024). By assessed acreage it sits above the national median by assessed acreage (38,628 lakes); its impairment list is among the longest nationally (one listed cause vs 23,610 assessed lakes).

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.
Where Inman 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: assessed size
The number that most separates Inman Lake nationally is assessed size: 125 acres, larger than 74% of the 38,628 lake-type units with an area on file.
Inman Lake: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Inman Lake. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Every filed use clears the bar
The filed use determinations for recreation are all Fully Supporting. Where an overall IR category still flags the unit, look at the cause list and report standing rather than treating the use row as empty.
Overall status: not supporting
The filer's overall status for Inman Lake is Not Supporting. That tile summarizes the assessment unit; the designated-use rows and cause list are the evidence behind it.
Typical cause-list length
1 listed cause is a middle-tercile list length among assessed lake-type units. Look to IR category and use outcomes for the distinctive reading.
According to the U.S. Environmental Protection Agency's ATTAINS program, Kansas carries 328 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Inman Lake 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.
| Designated use | Group | Verdict |
|---|---|---|
| Agricultural Supply Use--Irrigation | Other | Fully Supporting |
| Primary Contact Recreation | Recreation | Fully Supporting |
| Aquatic Life Use | Aquatic-life or related | Insufficient Information |
| Domestic Water Supply | Drinking-water supply designation | Insufficient Information |
The record
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 |
|---|---|---|---|
| Lead | Aquatic Life Use, Domestic Water Supply | 2022 | TMDL priority: Low |
Reading the record
Where Inman Lake sits among peers
8 of 11 Kansas lakes assessed this deeply were also judged fully supported
Kansas ruled definitively on 2 designated uses at Inman Lake and found every one of them supported, though the state recorded the cause below as not meeting criteria for Aquatic Life Use and Domestic Water Supply. The dataset shows 11 Kansas lakes judged to that same depth.
Kansas's assessed lakes are most often judged on 4 uses; this one was judged on 2.
| 1 | 2 | 3 | 4 | 5+ | |
|---|---|---|---|---|---|
| All supported | 7 | 8 (this record) | 15 | 53 | 0 |
| Mixed | Not possible | 3 | 1 | 222 | 1 |
| None supported | 1 | 0 | 5 | 2 | 0 |

Scale and rank
Inman Lake is one of 328 lake-type waterbodies reported to EPA from Kansas, and one of 304 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 125 assessed acres it ranks 10,084th 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 10,083 lakes with a larger one.
Awaiting a filing
The state has not yet filed a definitive fish-consumption verdict and a definitive aquatic-life verdict for this record; those fields populate when it reports them in a future Integrated Report cycle.

In context
Kansas context
ATTAINS carries 328 lake-type waterbodies in Kansas, 241 assessed as not supporting at least one use and 77 fully supporting. Among the 304 indexed units there, Inman Lake ranks 119th by listed-cause count (one listed cause) and 82nd by assessed size among the 304 with an area filed; it sits in the not-supporting set (241 statewide) . Its listed causes (Lead) sit outside Kansas's top-five list, which is led by Eutrophication.

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 KS-LM050301. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
