Description

The objective of this project is to construct 76 LW features along 2.1 miles of Hollow Tree Creek. These features will contain 271 pieces of LW, including 90 key pieces and 60 pieces with rootwads attached. The addition of these structures will enhance spawning and rearing habitats for both adult and juvenile salmonids. Additionally, seedlings and native plants will be planted in the riparian zone along the project reach.

Project Benefit

The installation of 76 LW features will provide a number of benefits to salmonids. These benefits include enhancing pool area and depth, increasing shelter complexity, sorting substrate for spawning habitat, increasing the frequency of floodplain and side channel inundation, aggrading the channel, capturing large and small wood, and providing velocity refugia during high flows.
