Pritchard Island Beach

Seattle, Washington

HOURS: 6 a.m. - 10 p.m.

ABOUT THE PARK:

Pritchard Island Beach is located in the Rainier Beach area, north of Beer Sheva Park. Several large cottonwoods flutter in the breeze as swimmers head for the raft, where they spring into the air from high and low diving boards. Others just sit on the beach admiring the view of Seward Park to the north and Mercer Island to the east. You'll find this a fine, quiet complement to the Atlantic City beach to the south,since there is no boat ramp ruckus here.

(From Brandt Morgan's Enjoying Seattle's Parks.)

PRITCHARD WETLAND:

Pritchard Wetland is a unique haven of native plants and wildlife, just south of Pritchard Island Beach. Walk the gravel path that starts at the edge of the parking lot; it winds through more than four acres of marshy wildlife habitat. Watch for muskrats and herons in Pritchard Pond, and listen for the songs of Chorus frogs in the spring!

All the plantings in Pritchard/Loon Wetland are native to western Washington wetlands. Look for Red-osier dogwood, fawn lilies, and Western red cedar saplings. For more information and maps to the park, please visit the Friends of Pritchard Beach web site.

Acreage: 19.1

MONITORING FREQUENCY

Pritchard Island Beach is sampled weekly from May 12th 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.
