Water Quality and Safety Concerns at Lake Sammamish

Lake Sammamish, a beautiful and popular recreational area near Seattle, offers swimming, boating, and fishing opportunities. However, like many lakes, its water quality can fluctuate, raising concerns about swimming safety. Understanding these potential risks is crucial for a safe and enjoyable experience.

Harmful Algal Blooms (HABs)

One major concern is the presence of harmful algal blooms (HABs). HABs are excessive growths of algae that can produce toxins harmful to humans and animals. These blooms can appear as green scum, foam, or mats on the water's surface. Contact with HABs can cause skin irritation, nausea, vomiting, and more serious health problems.

What to do: Check the King County Public Health website for current water quality alerts before heading to the lake. Avoid swimming or other water contact if a HAB is present. Keep pets away from affected areas as well.

Bacteria Levels

Another factor influencing Lake Sammamish's swimming safety is bacteria levels. Rainfall and runoff can introduce bacteria like E. coli into the lake, potentially leading to illness if ingested. High bacteria levels are more common after periods of heavy rain.

What to do: King County Public Health regularly monitors water quality and provides updates. Check their website before your visit for the latest bacteria level reports. Avoid swimming in areas with visible signs of pollution, such as excessive debris or runoff.

Other Potential Hazards at Lake Sammamish

Beyond water quality, several other factors can impact swimming safety at Lake Sammamish:

Cold Water: Lake Sammamish water temperatures can be surprisingly cold, even during summer months. Cold water shock can lead to hypothermia and impaired swimming ability.
Hidden Obstructions: Submerged debris and uneven lake bottoms present potential hazards for swimmers. Be cautious and avoid diving in unfamiliar areas.
Watercraft Traffic: Boats, kayaks, and paddleboards share the lake with swimmers. Maintain awareness of your surroundings and avoid areas with heavy watercraft traffic.
Wildlife: While generally not aggressive, wildlife like geese and other birds can affect water quality through their droppings. Avoid swimming near large bird gatherings.

Tips for Safe Swimming at Lake Sammamish

To minimize risks, follow these safety precautions:

Check Water Quality Reports: Before your visit, consult King County Public Health's website for the latest water quality information. Look for advisories concerning HABs and bacteria levels.
Choose Designated Swimming Areas: Stick to designated swimming areas for improved safety and water quality monitoring.
Swim with a Buddy: Never swim alone. A companion can offer assistance if needed.
Supervise Children Closely: Children should always be supervised by an adult while swimming.
Be Aware of Weather Conditions: Avoid swimming during storms or when weather conditions appear unsafe.
Enter the Water Gradually: Acclimate to the water temperature gradually to avoid cold water shock.
Avoid Alcohol and Drugs: Avoid alcohol and drug use before and during swimming.
Know Your Limits: Don’t overestimate your swimming abilities or push yourself too hard.
