The top part of the river is faster then the lower part and so more rapids and fast moving runs and pools are to be found but as we move downstream the water slows down a bit and the river flows through grassy meadows with numerous bends and deep pools. The fish can be found anywhere but the bigger fish are normally found in the deeper pools. Wading is easy all over but of course wading is not to be done in the deepest of pools.
The river flows through two lakes on it‘s way to meet the Big Laxa before going to sea and in the lowest part after both lakes the fish tend to be smaller but very willing to rise to anglers dry flies. There is also some char to be had, especially in and around the first and biggest lake. This river is dry fly heaven!
It seems trout are all over the place in this river and the rule of thumb is that there is a fish anywhere you think to look for it.
What flies to use
Klinkhammers, Shuttlecocks, Caddis, Gnats, Midges etc. for dry flies. Caddis and midge imitations for nymphs. If the conditions for streamer present themselves we suggest using minnow patterns and stickleback imitations alike. Black Ghost, Wooly buggers and Dog Nobblers have proven themselves as well as Muddler Minnow.
