2021 Kenai River Beaches

Bacteria monitoring on Kenai beaches began in May and continued through August of the 2021 recreational season. Sampling occurred every other week at North and South Kenai River beaches. Bacteria monitoring was conducted to evaluate potential public health risks indicated by fecal coliform and enterococci bacteria, and to notify the public when levels exceed state standards.

Virtual Beach

DEC is evaluating the EPA Virtual Beach model using data collected during the 2021 recreation season. The model uses local environmental data to forecast bacteria levels on recreational beaches. Check out the Frequently Asked Questions document on the Alaska Beach Program homepage to learn more about Virtual Beach.

2020 Kenai River Beaches

Bacteria monitoring on Kenai beaches began in late May and continued through the 2020 recreational season. Sampling occurred at North and South Kenai River beaches, upstream and downstream of the Kenai River gull rookery, and at the Warren Ames Memorial Bridge. Weekly bacteria monitoring was conducted to evaluate potential public health risks indicated by fecal coliform and enterococci bacteria, and to notify the public when levels exceed state standards.
