The Lower Junction City site was constructed to enhance both terrestrial and aquatic habitat quality. In-river work was done to increase habitat complexity through construction of slow water refuge habitats, reconnection of the floodplain with the river, and placement of in-river geomorphic and habitat features (e.g., construction of islands and wood structures). On-shore included revegetation of riverine and upland areas with native vegetation.
