The sedimentation rate over the past 10 years in the Hutt Estuary shows an overall trend of deposition, a relatively consistent moderately elevated sediment mud content, and a moderately shallow depth at which anoxic sediments occur. The estuary flats remain under pressure from sediment impacts related to poor water clarity and muddy
intertidal substrates, with a macrofaunal community
likely dominated by mud tolerant species.
