Another species affected by the dredging and the water quality is the winter run salmon. In order to maintain the water quality needed for this species' habitat, additional releases from upstream reservoirs will need to be made. These releases will negatively affect the amount of water stored in the reservoirs, which is needed for drinking water, agricultural purposes as well as providing cold water flows for the migration of the salmon. In other words, there may not be enough fresh water to make sure the salinity levels are maintained under the maximum amounts as well as serve all the other needs of the ecosystem and the people in the area.
