Good news on harbour health
The rate of sedimentation in Porirua Harbour is decreasing, according to the latest scorecard issued by the Porirua Harbour Trust.
The second annual State of the Harbour report, which charts progress towards returning the harbour to a healthy state, said sedimentation in the Onepoto and Pauatahanui arms was improving.
Trust chairman Grant Baker said the result was pleasing.
The feedback from sports clubs – yachting, boating, rowing, waka ama and kayak clubs were surveyed over the Christmas period – which were regularly using the harbour was also positive.
The general rating from the clubs on water quality was ‘‘good’’ and rub- bish that collects in the mouth of the Porirua Stream has risen from ‘‘very poor’’ last year to ‘‘fair’’ this year.
However, soft mud in the subtidal areas, poor water quality at beaches and shellfish gathering areas, and rubbish in Porirua Stream, were still issues of concern, Baker said.
‘‘The historical development and use of land around the harbour has resulted in the steady degradation of values that make the harbour special,’’ he said.
‘‘But the scorecard is starting to show a small amount of progress from the first report [last year].’’
Baker said steady and encouraging work was being done, with progress each year to be measured against the Porirua Harbour and Catchment Strategy and Action Plan.
