Pine Lake Park

Managed by King County Department Natural Resources and Parks

Located along the shores of Pine Lake, the wooded park offers swimming, boat launch, fishing pier, and two new play areas. Along with these amenities there is also a baseball/softball/open play field and a basketball court. Picnic facilities are plentiful and may be reserved. Because of its central location and beautiful wooded setting, the park is host to numerous community events, including the annual Summer Nights At The Park series of music concerts, plays and outdoor movies.

Formerly a King County Park, this 16-acre facility was transferred to the city of Sammamish after incorporation. Restoration projects completed to date include replacement of restroom fixtures and the construction of two new play areas.

COVID-19

Keep your distance from other people.

Practicing social distancing is still essential. Only go to the beach if you are able to keep 6 feet or 2 meters away from others. Follow the instructions provided by your local health authorities. If your community has asked that you remain indoors and away from others, do so. Spending a day in any crowded place is the worst thing we can do for our most vulnerable right now and will counter our efforts to curb the virus’s spread.

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 Tuesdays. Results are generally posted to the King County Lake Swimming Beach Bacteria Monitoring page by noon on Wednesday.

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.

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.

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.
