While working for Otak Kevin collaborated on multiple 2013 Emergency Watershed Protection Phase II projects on Left Hand Creek, Saint Vrain Creek, and Fall River. The Foothills project on Left Hand Creek was a large and challenging project for the Lefthand Watershed Oversight Group. I worked with a team of river professionals at Otak, FlyWater, and Iron Woman to design and construct this $4 million project.
Pictured below is a large wood structure during construction to protect the left bank of the river and the Streamcrest neighborhood below.
The root wads are used to create a guide bank on the outside of the bend. The wood serves two main functions 1) protect the bank from erosion and 2) encourage scour and pool formation at the end of the root wad. When the root wads are installed, the trunk of the tree is buried in the bank and weighted down with large boulders. Large wood structures have gained popularity in river restoration projects to create physical habitat for aquatic species and to return woody material to river reaches where it has been removed.
