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.
