Good news on har­bour health

Kapi-Mana News - - NEWS - By KRIS DANDO

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.
