About Tasman District Rivers and Rainfall

The Tasman District has catchments in the west that receive over 6000mm of rain each year. We also have areas that are sheltered from the westerlies and receive as little as 600 mm of rain each year. Most catchments begin in the mountains on land that is National Parks and reserves. From small creeks and streams our rivers grow to flow out to the sea in Tasman Bay, Golden Bay and the north west coast.

Uses and Values of Rivers and Streams

Tasman’s waterways provide valued places for:

  • swimming, boating, angling and other recreation;
  • a home for aquatic plants and animals;
  • a source of food;
  • traditional cultural values;
  • water for drinking;
  • water for hydroelectricity;
  • irrigation for horticulture and agriculture.

Tasman District Council works to ensure all these values are maintained or enhanced and used in a sustainable way.

Maori have strong traditional and historical links with wetlands and waterways. These are spiritually significant and closely linked to the identities of tangata whenua.
