Lake Grasmere

Access Access is via a track that leads of SH73 just south of the small settlement of Cass.
Description 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 refuge, 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 the season.

Methods 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. There is very good access to much of the lake for land-based anglers.
Recommended tackle 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 strong run out into the lake. Tippets of around 3kg and leaders of 12 feet are ideal. Spin rods capable of casting a 5 - 10 gram lure.
Recommended lures Dry flies: Adams, Kakahi Queen, Twilight Beauty, Deers Hair Sedge, cicada , Black Gnat, Blowfly and Humpy in sizes 12 - 16.

Nymphs: Hare and Copper, Hare's ear, Prince nymph, Stonefly and Pheasants tails in sizes 10- 14

Wet flies: Bully patterns such as Mrs Simpson or Hamills Killer, Woolly Buggers in sizes 6-10

Spinners: Rapalas in green and gold patterns (dark patterns are best for this lake), Tobies and Mepps.

Tributaries There are no tributaries or streams of note for the angler. The outlet stream tends to be weed infested and overgrown.
