Streams, Lakes and Wetlands

Bellevue stream Streams, lakes and wetlands are critical areas protected from development, and constitute a natural part of Bellevue's drainage system.

Bellevue has more than 60 miles of streams.
Streams provide a natural setting and feeding areas for chinook, coho, sockeye, steelhead, cutthroat trout, waterfowl and other wildlife.
In Bellevue it's illegal to remove plants from or disturb stream corridors. Please call Development Services at 425-452-4188 for more information.
In addition to bordering Lake Washington and Lake Sammamish, Bellevue has three small lakes – Phantom Lake, Larsen Lake and Lake Bellevue.
Bellevue has more than 800 acres of wetlands.
Wetlands slow down stormwater runoff, which prevents flooding and erosion, and serve as a rich habitat for fish and wildlife.
If you see signs of pollutant spills near a storm drain or water body, please call 425-452-7840.

To receive a guidebook to Bellevue’s streams, lakes, wetlands, watersheds, salmon migration and other information, call the Utilities Department and ask for a copy of Water All Around Us.

Some common water quality concerns are iron-oxide deposits and blue-green algae.

To volunteer to help our waterways, see Stream Team. To volunteer to mark storm drains with a pollution prevention message, call Karren Gratt at 425-452-6166. By appointment only.
