However, before you dive in, it's crucial to understand the safety aspects of swimming in this lake. This comprehensive guide will address common concerns and provide you with the information you need for a safe and enjoyable swimming experience.

Water Quality Concerns in Lake Sammamish

While Lake Sammamish is a beautiful lake, its water quality can fluctuate. Several factors influence its safety for swimming:

Blue-Green Algae (Cyanobacteria):

The Risk: This is perhaps the biggest concern. Blue-green algae blooms can produce toxins harmful to humans and animals. Contact can cause skin irritation, nausea, vomiting, and in severe cases, liver damage.
Monitoring: King County Public Health regularly monitors the lake's water quality. Check their website ([insert King County Public Health website link here]) for the latest advisories and bloom reports before heading out. Look for signs posted at popular access points.
Identifying a Bloom: Blue-green algae blooms often appear as greenish-blue scum, mats, or streaks on the water's surface. They can also look like pea soup or paint. Never swim in water that looks suspicious.

Bacteria Levels:

Sources: Runoff from storms and other sources can introduce bacteria into the lake, potentially leading to illness if swallowed.
Monitoring: King County Public Health also monitors for bacteria levels. Refer to their website for updates on water quality.
Reducing Risk: Avoid swimming after heavy rainfall. Wash your hands thoroughly after swimming.

Other Potential Hazards:

Cold Water: Lake Sammamish's water temperature can be surprisingly cold, even in summer. Cold water shock can lead to hypothermia and drowning. Enter the water gradually to allow your body to adjust.
Hidden Obstructions: Submerged debris or uneven lake bottoms present tripping hazards. Be cautious and aware of your surroundings.
Wildlife: Although encounters are rare, be mindful of wildlife in and around the lake.
