KIRKLAND, Wash. – Due to the discovery of high levels of Fecal Coliform Bacteria in Lake Washington at Marina Park Beach in Kirkland, humans and animals should not go in the water. Advisory signs warning about the high levels of “Fecal Coliform Bacteria” have been posted at the beach which is located at 25 Lakeshore Plaza. The beach will be closed for at least a week as testing is done to determine the source of the bacteria.

Fecal coliform bacteria is an indicator of sewage pollution and is monitored weekly by the Seattle-King County Public Health Department. Most bacteria present are typically assumed to be of non-human origin. Many animals such as dogs and waterfowl can contribute to this form of bacteria in the water. The City of Kirkland will be conducting testing on Monday, June 27, 2016, to determine the source of the bacteria.

For more information, visit the King County website and search for "fecal coliform bacteria." Updates about Marina Beach Park and other Kirkland waterfront parks will be posted to the City’s News Room webpage. To receive news releases via email, subscribe at and select “City News Releases.”
