Waverly Beach Park

Kirkland, Washington

This park has some of the best views of Seattle and it feels like you are in your own private park. Bring the family and enjoy a picnic at the park and stroll to the end of the dock where one can rest on the benches and enjoy the panoramic views of Lake Washington.

The park sits on 2.76 acres of prime waterfront real estate right on Lake Washington. It features a public dock, picnic tables, benches, restrooms, children’s playground, open lawn areas, on-site parking, enclosed swimming area, fishing area, and windsurfing area. Not only that, but you will find that there is a privately run refreshment stand and a market operating during the summer months. This hidden treasure is well maintained and seamlessly integrated into the surrounding hillside.

MONITORING FREQUENCY

Waverly Beach Park is sampled weekly from May 12th to September 16th

SOURCE INFORMATION

The King County Department of Natural Resources and Parks monitors water quality at designated swimming beaches in the county from May to September. Water quality data is collected weekly, usually on Mondays. Results are generally posted to the King County Swimming Beach Bacteria Monitoring page by noon on Wednesday.

During the sampling period, Puget Soundkeeper Alliance regularly updates the Swim Guide to reflect the most current information. Local health officials use the following protocol to make closure determinations – A day’s average E. coli value is over 1000 CFU/100 mL – OR - The average of the E. coli values for the three most recent sampling days is over 200 CFU/100 mL. The three-day average is calculated using the geometric mean (geomean). The unit of measure is a CFU which stands for Colony Forming Units.

A beach is marked Green (open) when both of these protocols are met.
A beach is marked Red (closed) when these criteria are not met and the public health officials have closed the beach.

A beach may also be marked Red if there is a Harmful Algal Bloom (HAB) reported at the beach. A beach is marked Grey when current water quality data is not available. The King County Water and Land Resources Division (WLRD) collects and analyzes the samples. Public Health Seattle & King County is alerted when bacteria or state algal toxin thresholds are exceeded and determines the health and safety implications of the bacteria and algal toxin data collected, and they work with King County WLRD and the local park manager to post an advisory.
