| A private levee constructed years ago along the Walla Walla River on the Lampson property is one of many that constrict the river's ability to meander and provide fish habitat complexity. This project helped to fund the construction of a levee setback, secondary channel creation, and revegetation of the riparian area and floodplain along a half mile reach. Thirty-six acres of conservation and flowage easements exist where this project expanded the Walla Walla River floodplain. This area is at the upper end of several miles of levee that continue below this reach. Half a mile of riparian habitat has been planted along this known (ESA listed) steelhead and spring chinook spawning habitat and bull trout rearing habitat. The river bank where the levee was removed has been designed and improved for stability and fish habitat, utilizing features such as J-hook, root wads, and a roughened channel. |
