Rangitata River

 

The Rangitata River is a big river offering some of the best salmon fishing in New Zealand. It also supports good stocks of brown and rainbow trout which are less seldom targeted by anglers.

Water Conservation Order A WCO was passed in 2006 identifying the outstanding characteristics of the Rangitata River. The order lays down constraints on damming, alteration of river flow and form and water quality, and maintenance of fish passage. The WCO recognises the economic value of the river, and provides for some existing uses including the RDR.

Fish type Salmon, rainbow and brown trout
Situation

The Rangitata is a snow fed river that originates in the Southern Alps and flows in a south-easterly direction to the coast south of Ashburton.

Driving south from Christchurch, SH1 crosses the Rangitata River at Rangitata between Ashburton and Timaru.

View the river flow

Heavy rainstorms between November and early January can make the river dirty and unfishable for a few days. This occurs when the river flow at the Gorge exceeds about 125 cumecs.

As the discoloured waters clears, there is good fishing to be had. The best fishing is when the water is slightly coloured and the flow is in the range 80-110 cumecs (which equates to 50-80 cumecs at SH1).

Description

The Rangitata is prone to floods and freshes from high rainfall and snow melt, particularly from the north-west wind conditions that occur frequently throughout the main salmon season from November to March. It is unstable, braided and often silt-laden

The Rangitata is a big river and care is required. At the mouth, and particularly from the beach, watch out for waves washing onto shore. When crossing braids of the river, choose your crossing point carefully.

Salmon fishing

When to fish

The salmon fishing begins around mid November. Between November and mid-February, the best stretch of water to fish is below the SH1 bridge. From February to April, above SH1 provides the better fishing.

Recommended tackle

Lure fishing:
- A 9-11 kg line
- A feathered lure plus added weight

Spinning:
- A 7-9 kg line
- A Zed spinner,
silver white or yellow, with 14-28 gm weight, or a Colarado spoon and lead.

Trout fishing

In the estuary

During October-December sea run browns are to be found in the estuarine area.

Above the Gorge

Both rainbow and brown trout are to be found above the Rangitata Gorge from 1 October when fishing season begins, through to about mid February when the spawning salmon arrive. This is the best place on the Rangitata for trout fishing.

Fish numbers and size

There are good stocks of both rainbow and brown trout above the gorge and in relatively inaccessible side creeks such as Deep Stream and Deep Creek.

Recommended tackle

Lure fishing:
- A 10lb plus line for salmon, 6lb for trout
- A smelt type lure such as Grey Ghost, Parsons' Glory, or Mrs Simpson, with up to 28 gm lead. Nymphs and flies such as yellow Dorothy

Spinning:
- A 2-4 kg line (though use heavier for salmon)
- A Tasmanian Devil or silver Toby
