2021 Ketchikan Beaches


Bacteria monitoring on Ketchikan beaches will begin in late May and continue through the 2021 recreational season. Sampling will occur every other week at 12 beaches. Bacteria monitoring is conducted to evaluate potential public health risks indicated by fecal coliform and enterococci bacteria, and to notify the public when levels exceed state standards. For more detailed information, click on the document links below.

Virtual Beach

DEC will be evaluating the EPA Virtual Beach model (VBeach) during the 2021 recreation season. The model uses local environmental data (temperature, tide, etc.) to forecast bacteria levels on recreational beaches. Check out the Frequently Asked Questions document below to learn more about VBeach and how DEC is piloting it this summer.

2020 Ketchikan Beaches

Bacteria monitoring on 12 Ketchikan beaches began in May and continued through the 2020 recreational season. Weekly marine water sampling was conducted to evaluate potential public health risks indicated by fecal coliform and enterococci bacteria, and to notify the public when levels exceeded state standards. For more detailed information, click on documents linked below and previous year tabs above.

Off Season Monitoring

An off-season monitoring project began in October 2020 and continued through January 2021. Sampling consisted of one sampling event per month and was conducted and funded by the Ketchikan Indian Community. Monitoring was planned for the entire off-season, through the month of April, however funding constraints resulted in ending the project in January.
