Water extraction from Lake
Ohau into the Ohau Canal has severely reduced the Ohau River
flow. It is still a reasonably sized river however with a
number of good runs and pools, particularly the section of
the river from where it leaves Lake Ohau down to the Ohau
B Power Station. Due to its glacial origins however, it often
contains a degree of glacial silt that discolours the water
making spotting of fish difficuly. Consequently, fishing blind
with a nymph or spinner are the favoured options when fishing
||There is good access to the
upper section from a road that follows both banks.
||This water is best fished with
a nymph or spinner. At times the fish do rise to hatches and
so the angler should be armed with the approriate flies etc
especially during the late spring and summer months.
||Rods of around 6 weight with
a floating line for the nymph fishing or a spin rod capable
of casting lures between 7 - 12g are recommended.
