Safety Alert: Houghton Beach Closed to Swimming, Humans and pets cautioned to stay out of water

Routine weekly water testing revealed high levels of fecal coliform bacteria in Lake Washington at Houghton Beach in Kirkland, leading City officials to warn against people and pets entering into the water. Advisory signs warning about contaminated water have been posted at the beach, which is located at 5811 Lake Washington Blvd NE.

The City of Kirkland will be conducting follow-up testing as early as Monday, August 20, 2018, to determine the source and levels of the bacteria. The beach will be closed until at least Wednesday, August 22, 2018, as testing is done to determine the source of the bacteria. Houghton Beach will reopen when testing shows the water is safe.

The Seattle-King County Public Health Department tests beaches throughout King County on a weekly basis. 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.  Beach visitors are asked to refrain from feeding waterfowl such as ducks and geese since waterfowl populations raise levels of fecal coliform.
