trout with a good number of rainbow trout liberated into
the lake each year (1,400 were liberated by Fish and Game in
Nov 2007). Fish average between 1 - 2 kg though fish over 3
kg are not uncommon.
Lake Grasmere is located in
a broad valley surrounded by high mountains between Porters
Pass and Arthurs Pass.
Access is via a track that leads
of SH 73 just south of the small settlement of Cass.
Lake Grasmere is a small
oval shaped lake high in a mountain valley. It is in a wide
valley and mostly surrounded by distant snow covered mountains.
The north-eastern shoreline is generally inaccessible being
quite steep and rocky and with bush-clad banks. The rest of
the lake is generally accessible though the shoreline can
be quite swampy in places especially early in the season.
As the lake is also a bird and wildlife reguge, there is
a high bird population and as a result the water quality is
sometimes not the best. On clear days however fish are easy
to spot as they cruise the shoreline. This is a very scenic
lake and a pleasure to fish on a beautiful summer or autumn
day. Being in the high country however, it can receive strong
cold winds at times and can be challenging to fish early in
All methods work well on the
lake. Dry fly fishing can be excellent from Dec through to March
with Nymph and spinning / wet flies working well all the season.
No boat fishing is allowed.
5 to 7 weight. 9 foot fast
action graphite are ideal as these can cut through the winds
that often blow in the area. Have plenty of backing as some
fish are large and can make a very gopod run out into the
lake. Tippets of around 3kg and leaders of 12 feet are ideal.
