Stream Restoration

Extensive logging removed riparian trees throughout many watersheds, which has led to deteriorating streambanks, a discharge of sediment and impacts to the stream channel.  This continuous watershed instability negatively effects water temperature, sediment load and fish habitat.  ET utilizes a restoration approach called Natural Channel Design to restore critical stream parameters. ET’s Natural Channel Design approach includes: 

  • Assessment and surveying of the stream using Natural Channel Design methodology.

  • Collection survey data and biological data necessary to complete project permit applications and design a rehabilitation project.

  • Monitoring the water temperature to select project site(s).

  • Designing a stream restoration project to restore watershed function and stability.

  • Restore the stream channel’s shape, dimension and profile.

  • Enhance instream trout habitat by strategically positioning large woody debris, rock vanes and “J” hooks into the channel.

  • Reconnect the channel to the floodplain. 

  • Create new floodplain benches and wetlands to retain water on the landscape. 

  • Raise the groundwater table.

  • Stabilize streambanks with use of Toe Wood/Root Wads.

  • Rehabilitate the riparian overhead tree canopy with native vegetative species.
