Road-Derived Fine Sediment Control (Funded
1999)
Current Status: Closed Complete
Over the past 5 decades, salmonid spawning habitat has been degraded & reduced
as a result of sediment deposition in spawning gravel in tributaries & the
lakeshore of Lake Ozette due to forest practices and roads. This sediment
deposition has been identified as a major limiting factor for the recovery
of the ESA listed Lake Ozette Sockeye Evolutionary Significant Unit. The
Recovery Team has determined that an efficient way to minimize road-derived
sediment loads is to selectively place cross-drain pipes as a means of
rerouting sediment to the forest floor, prioritized to maximize the reduction
of sediment delivery to the channel network. A detailed road survey/inventory
has been conducted on all Rayonier Timberlands roads in several sub-basins
of Lake Ozette. Tons/year of sediment delivery from roads to the channel
network for each stream-bearing drainage structure has been calculated.
This project will install 30 cross drains to immediately reduce sediment
inputs to several priority streams. The project will monitor effectiveness
of the cross-drains during times of moderate to heavy rainfall and road
use, as well as monitor streams & channels near roads to assess degree
of turbidity. Monitoring will also include post-project.
