California sewage discharges in 2020

202 records of sewage discharges and water advisories in California dated in 2020, newest first. Each record keeps the source's own times and wording; a record from the last three months, or one that sets a status now, also has a page of its own.

By type: Cyanobacteria advisory (harmful blue-green algae)202

By source: California State Water Resources Control Board (FHAB program)202

2020 in other states: Connecticut, Florida, Illinois, Maine, Michigan, New Hampshire, New York, North Carolina, Pennsylvania, Rhode Island, Vermont.

Source: the agencies, sewer operators and EPA records named on each row and on the Sources page. Updated 2026-11-06 09:03 UTC.

Cyanobacteria (harmful blue-green algae) can make water unfit for contact; the issuing authority decides when its advisory ends.
