Future land acquisitions by the Yakama Indian Nation (YIN) within the Wapato floodplain require the development and implementation of a scientifically based restoration plan which underscores and expedites the river's ability to rework and restore the structural complexity within this critical floodplain. Consequently, augmented structural complexity should reflect a concomitant increase in the ability of aquatic and terrestrial organisms to complete their various life-stages, which promotes higher levels of biocomplexity, bioproduction, and ecosystem integrity. As such, the river becomes the principal restorative tool employed throughout this process. However, this strategy necessitates substantial modifications to existing cultural features. Examples include, but may not be limited to, dike removal and setback, reconfiguring specific road segments and highway bridges, and grade control structures. These modifications must occur if normative river processes are to approximate historic conditions across the longitudinal, lateral, and vertical scales of this floodplain.
(1) To develop a preservation/restoration plan for the Wapato floodplain that achieves the following:
(2) Use the objectives listed above to adaptively manage and scientifically assess the long-term effects of reestablishing connectivity within the Wapato floodplain.
