Pine Lake Park

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.

SOURCE INFORMATION

During the sampling period, Puget Soundkeeper Alliance regularly updates the Swim Guide to reflect the most current information.

Local health officials follow the Ten State Standard –a geometric mean of 200 fecal coliforms with no single sample exceeding 1000 – to determine whether a swimming beach is polluted. The unit of measure is a CFU which stands for Colony Forming Units.

A beach is marked Green (open) when a single sample is below 1000 CFU/100ml and the geometric mean of the five most recent samples is below 200 CFU/100ml.

A beach is marked Red (closed) when either a single sample exceeds 1000 CFU/100ml or a geometric mean of the five most recent samples exceed 200 CFU/100ml

A beach is marked Grey when current water quality data is not available.

If a sample is found to exceed the Ten State Standard three new samples are collected. If the average of these samples confirms the results from the routine sample, Public Health Seattle & King County is alerted and determines the health and safety implications of the bacteria and algal toxin data collected and works with King County and the local park manager to post an advisory.
