Streams, Lakes and Wetlands
Streams, lakes and wetlands are critical areas protected from development, and constitute a natural part of Bellevue's drainage system.
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 Utilities at 425-452-6166. By appointment only.
