Transferred to the city of Sammamish on January 1, 2003, Beaver Lake Park offers opportunities for recreation, hiking, and exploring its 54 forested acres. In addition, Beaver Lake is an attractive fishing spot.

Facilities include a large pavilion and lodge with ADA accessible public restrooms on the north side; and three ball fields, a picnic shelter, play structure, and restrooms on the south side. Unpaved hiking paths connect the north and south sides of the park.

The Lodge at Beaver Lake is a Northwest log building, which houses weddings, private parties and meetings. Discounted rates are available to eligible community groups for use during the weekdays and Monday through Thursday evenings.

MONITORING FREQUENCY

Beaver Lake Beach is sampled weekly from June 1st to September 1st

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 24 hours after the samples are collected.

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.
