Marlborough's Aquifers
-
Are Are Creek Gravels Aquifer
Are Are Creek is a Northbank tributary of the Wairau River which drains the lower Kaituna Valley, north-west of Renwick.
-
Benmorven Aquifer
The Benmorven area is underlain by the most highly confined of the Southern Valleys' aquifers and contains the oldest groundwater, with the lowest yielding wells.
-
Brancott Aquifer
The Fairhall-Brancott Valley is home to some of the original grape plantings in Marlborough.
-
Coastal Wairau Plain Aquifers
The coastal aquifers occur at depths of greater than 30 metres below the surface, and are located within several kilometres of the Te Koko-o-Kupe/Cloudy Bay coastline.
-
Deep Wairau Aquifer
During the 1997/98 drought a number of irrigation supply wells in the Fairhall area ran dry and owners were forced to drill deeper in search of water.
-
Fairhall River Gravels Aquifer
The Fairhall River drains the southern hills catchment.
-
Lower Waihopai Aquifer
The Lower Waihopai Aquifer is the name given to all groundwater resources underlying the broad floodplain of the Waihopai River north of Craiglochart bridge.
-
Northbank Tributaries
Various creeks and streams drain the Richmond Range and flow into the Wairau River on its northern bank, opposite Wairau Valley.
-
Omaka Aquifer
Various creeks and streams drain the Richmond Range and flow into the Wairau River on its northern bank, opposite Wairau Valley.
-
Omaka River Aquifer
Groundwater losses from the Omaka River collect in the adjacent or underlying gravels to form a multi-layered groundwater system. This is known as the Omaka River Aquifer.
-
Rārangi Shallow Aquifer
The boundaries of the Rārangi Shallow Aquifer are the Pukaka River, Pukaka Hills, Wairau Diversion channel to the south, and the Pacific Ocean.
-
Riverlands Aquifer
The Riverlands Aquifer was recently defined as a separate system in recognition of its isolation from the Wairau River, low yield and old groundwater.
-
Southern Marlborough Groundwater Resources
There is little evidence of the presence of high-yielding aquifers in the Lower Awatere Valley, Blind River, Waima River or Flaxbourne areas.
-
Southern Springs
The Southern Springs occupy the area between Woodbourne and Blenheim, with northern and southern boundaries in the region of Middle Renwick Road and New Renwick Road.
-
Taylor River Related Aquifers
Associated with the Taylor River are two groundwater systems. A shallow aquifer known as the Taylor River Gravels Aquifer is linked to channel flow.
-
Tuamarina River Valley Aquifer
The Tuamarina or Waitohi Valley separates Picton from the Wairau Plain and is drained by the Tuamarina River.
-
Waikakaho River Gravels Aquifer
The Waikakaho River is a Northbank tributary of the Wairau River located between Kaituna and Tuamarina.
-
Wairau Aquifer
The Wairau Aquifer underlying the northern Wairau Plain is the highest-yielding system in Marlborough due to a perennial source of recharge from the Wairau River.
-
Wairau Valley Aquifer
The Wairau Aquifer underlying the northern Wairau Plain is the highest-yielding system in Marlborough due to a perennial source of recharge from the Wairau River.
-
Woodbourne
Sandwiched between the relatively water-rich Wairau Aquifer to the north, and the water short Southern Valleys to the south, is Woodbourne.
