Delta projects will accrete at a rate sufficient to restore historical wetlands and will keep up with sea level rise, given restoration of tidal prism and adequate connection to river flows that contain sufficient suspended load.

Notes

• Nisqually Refuge Restoration is removed from the mainstem river, which has reduced sediment budget due to Alder Dam.
• Distributary switching affects distribution of sediment.
