In 2009, several restoration projects were undertaken in the Stillaguamish watershed by the Stillaguamish Tribe and the cities of Arlington and Snohomish County. Over 13 acres of invasive plants were treated across 7 sites. Over 2,600 native trees and shrubs were planted across 6 sites totaling 15.1 acres. Snohomish County completed the North Meander project, increasing side channel habitat by 1.8 hectares. The City of Arlington planted 2,000 trees and shrubs along Eagle Creek and restored fish passage at two sites on the Portage. Educational programs were also conducted.

13. Snohomish County - North Meander Project

14. North Meander increases
side-channel slough
habitat by 1.8 hectares an increase of 18.5% over
existing amounts - or 8%
of the historical loss in
lower river.
Appropriate depths (>1.0
m), slow water velocities
(<30cm/s), and complex
edge and cover are
provided for, especially
with woody debris
placement.
2009 woody debris
exceeds 1,200 pieces/km –
the most abundant LWD
in watershed after Boulder
River.
