Kellogg Beach is a saltwater beach in Del Norte County, California. Across 93 bacteria samples collected between 2022 and 2025 at nearby monitoring stations, it earns a Beach Safety Grade of D — Poor.
About 15% of samples at Kellogg Beach exceeded the EPA Beach Action Value of 235 CFU/100 mL for Escherichia coli — the threshold at which water managers typically post a swimming advisory. In practice that means the safe-swimming limit was frequently crossed here over the monitored period. Bacteria samples frequently exceed the safe-swimming threshold; swimming advisories are common here.
The evidence behind this grade is deep for a beach page: 93 results from 8 monitoring stations, spanning 2022 to 2025. Enough sampling, from enough places, over enough seasons that one bad week can't drive the letter.
Kellogg Beach is currently listed as inactive in the EPA beach-monitoring program, so it may no longer be routinely sampled. Its grade reflects the water-quality results collected while it was active — useful history, but confirm the beach's current status and any local advisory before you visit.
