Description Riparian vegetation was analyzed along six Lower Skagit River tributaries using GIS and orthoimagery. The tributaries were Carpenter, Fisher, Hansen, Lake, Nookachamps, and the East Fork Nookachamps Creeks.

The 2004 Lower Skagit River Tributaries Temperature Total Daily Maximum Load (TMDL) study determined that these tributaries have temperature impairments. The TMDL study also made recommendations for increasing shade-producing vegetation along the creeks.

This report summarizes the changes in vegetation as a result of voluntary shade enhancement efforts for the six creeks between the years 1990/1998 and 2006.

Report revised in April 2008: The boundary delineations of Carpenter, Fisher, and East Fork Nookachamps Creeks were revised to be consistent with uppermost Department of Ecology stream temperature sensors.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
