The Mararoa River is a fast flowing medium-sized
river that has a very good stock of brown and rainbow trout. It
has several distincly different types of water along its length
and so will offer something for all anglers and skill levels. A
very attractive medium sized water to fish.
The Mararoa River rises in the
Livingston and Thomson mountains and flows south to enter the
northern tip off the North Mavora Lake. It is the outlet for
the North Mavora Lake and flows a few kilometres before entering
the South Mavora Lake. On leaving South Mavora it flows south
to join the Waiau River at the Mararoa Weir near Lake Manapouri.
The Mararoa provides many
kilometres of excellent fishing water for a good population
of both rainbow and brown trout.from its headquarters to the
confluence with the Waiau
river it provides a wide variety of fishing.
Upper reaches
Description
The upper reaches flow through a remote
tussock valley from a series of small tarns (small lakes)
high in the Livingston Mountains. The water through this section
is generally very clear though can be discovered early in
the season from snow melt.the river in the section is quite
small and flows over gravel beds that are easily waded. Fish
can generally be spotted in the clear water and they seem
to get bigger (and fewer in number) the further upstream you
walk.
The section bewteen the two lakes is deep
and not easily accessed. It holds reasonable numbers of fish
that rise freely but always seem to be frustratingly out of
casting range.
Fish numbers and size
Fish numbers in the section above North
Lake Mavora a reasonable with fish averaging around 1.5 kg
but going much bigger in the upper reaches.
Access
A four-wheel-drive track follows the eastern
side of North Mavora Lake and will take anglers to the Mararoa
river approximately 1 km above its confluence with the lake.
Middle reaches
Description
The middle reaches describe that part of
the Mararoa river between the outlet at the South Mavora Lake
and State Highway 94 which crosses the river near The Key.
As the outlet for the South Mavora Lake,
the Mararoa becomes a much larger river and flows quickly
down over a rocky and stone bed. Like most rivers that drain
from a lake, it remains relatively clear even after rain.
the river flows relatively quickly through long runs through
the section though it is possible to cross in a number of
places especially during the dry months. The banks can often
be heavily covered with vegetation making casting difficult.
The wind which can sweep down from the North can make for
difficult fishing conditions as well.
Fish numbers and size
In the section closest to the Mavora Lakes
most of the fish are rainbows while in the lower sections
near state highway 94, brown trout make up the majority of
the fish. Fish numbers are high and mostly in the 1 to 3 kg
range.
Access
There was good access to this section of
the river along Mavora Lakes Road which runs alongside the
river for most of its length.
Lower reaches
Description
The lower reaches of that section of the
river between state highway 94 and the confluence with the
Waiau
river.
The river in this section flows much more
quickly between Willow and Gorse covered banks. Trout are
much harder to spot in this area due to both the extra colour
in the water and the strong current. It can be very difficult
to fish when the river has inceased water flow and is best
fished late in the season after a drier period. This section
is still very worth exploring as it holds a good head of fish.
Fish numbers and size
Both rainbow and brown trout (with brown
being predominant in this section. Most fish are in the 1
- 3 kg range.
Access
Access can be gained where SH 94 crosses
the river but much of this section requires some walking (and
do seek the landowners permission before crossing their land)
Methods
Different methods suit different
sections of this long river. Much of it is excellent dry fly
and nymph water though anglers should try what the method they
are most comfortable with. Some areas require very skilled casting
to avoid the bankside vegetation.
Recommended tackle
9 foot fly rods with a weight
6 -7 line. Reasonably long leaders are required in the middle
and especially the very clear upper reaches.
Recommended lures
Nymphs:
Smaller lightly weighted slim profile flies such as a Dads
Favourite Nymph, Pheasants
Tail, Pheasant
Tail Emerger or Halfback
in the upper reaches. Heavier flies in the middle section
with some weight being necessary in the lower reaches. Most
fly patterns (especially Mayfly
emerger types) work well. In the middle section try some
flies with peacock herle such as a Theo's
Bomber.
Wet flies:
Small wet patterns such as spiders or March
Brown spiders in the middle and upper sections (or during
an evening rise) or if fishing deeper try a Woolly
Bugger or Matuka
pattern
