This waterbody in one line
Lake Lindero, a reservoir in California, is assessed as not supporting one or more designated uses, with 7 listed impairment causes in the state's most recent Integrated Report cycle (2020). By assessed acreage it sits below the national median by assessed acreage (38,628 lakes); its impairment list is among the longest nationally (7 listed causes vs 23,610 assessed lakes). Aquatic life is assessed as not supporting. California assesses commercial and sport fishing 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.
Lake Lindero 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: cause-list length
The standout filed fact is cause-list length: 7 listed impairment causes, a longer list than 99% of assessed lake-type units (n=23,610). List length tracks how states sample and code, not a severity score.
No ruled-on use clears the bar
On the uses this filer ruled on, fish consumption, 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.
Lake Lindero: Category 5, TMDL still owed
Category 5 is the Integrated Report band where a TMDL (or equivalent) is still expected for Lake Lindero. Read the listed causes and any cleanup actions filed beside them before treating the overall status tile as a finished restoration story.
Small within California
State size rank 182 of 195 puts Lake Lindero toward the small end of California's indexed lake-type units with an area.
Overall status: not supporting
The filer's overall status for Lake Lindero 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, California carries 607 filed lake-type waterbodies in the August 2026 extract, and this page renders the assessment record EPA assigned to Lake Lindero 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 |
|---|---|---|
| Commercial and Sport Fishing | Fish-consumption or fishery | Not Supporting |
| Non-Contact Water Recreation | Recreation | Not Supporting |
| Warm Freshwater Habitat | Aquatic-life or related | Not Supporting |

Scale and rank
Lake Lindero is one of 607 lake-type waterbodies reported to EPA from California, and one of 195 whose reported record carries enough populated assessment or gauge data for this site to list and index it. At 14 assessed acres it ranks 29,140th 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 29,139 lakes with a larger one.

In context
California context
ATTAINS carries 607 lake-type waterbodies in California, 202 assessed as not supporting at least one use and 22 fully supporting. Among the 195 indexed units there, Lake Lindero ranks 7th by listed-cause count (7 listed causes) and 182nd by assessed size among the 195 with an area filed; it sits in the not-supporting set (202 statewide) . Its listed causes (Algae, Chloride, Eutrophication, Odor, Selenium, Specific Conductivity, and Trash) sit outside California's top-five list, which is led by Mercury.

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 CAL4042300019990201145528. Counts and percentiles are computed across all lake-type records PlainLakes ingests from ATTAINS.
