Efforts to bolster Hudson River Estuary fisheries have focused a great deal on tributary dam removals. However, concern for sediment impacts often forestalls these projects. In the case of the Hudson, stakeholders have questioned whether sediment mobilized during dam removal might adversely affect water quality and submerged aquatic vegetation in the estuary. Others have pointed the potential benefits of releasing impounded sediment to downstream tidal marshes, which need to accumulate sediment to keep pace with sea level rise.
