Take the minor road from Ardgay towards Rosehall. Go past Carbisdale Castle and park at Inver house (OS map ref. 567965). Do not obstruct entrances or gateways. Cross the stile and keeping to the fence line, walk down to the Kyle.
At the Scap (also known as the Scarp), the Kyle narrows and the whole stretch to just above the mouth of the Shin can be fished. Roll casting helps under the trees. The flow at the Scap is affected when power is being generated at Shin Power Station.
Paul Moran has kindly put down a few thoughts on fishing at the Scap:
In Low Water:
Begin just below the old marker post indicating “Fly Only”. In Low water/Summer Levels enter the water at the point where the Cows have worn a path to the riverside. The wading at the Scap is fairly easy and there are no large stones or rocks to trip up the unwary angler. Work your way downstream moving at least a yard after each cast (some favour a square cast here and some prefer casting at an angle of 45 degrees). In Low water conditions (when the stones below where the small burn enters the Kyle on the right bank are showing) you can fish until you are parallel to the second post on the right bank, if the stones are covered then it is best to cease fishing at the first post as there is a fairly large deep hole and it is unadvisable to continue further. It is best to come out the water and walk round to continue fishing down about 3 yards above the row of trees. Wading is possible down to end of the row of trees but do not go any further from the bank than 2ft as there is a deep channel that runs parallel to the trees, a roll cast or single spey off the left shoulder is preferable here due to the steep bank at your back.
In High Water:
When the Kyle is in spate the Scap will still be fishable (some might say that it fishes better when the water is high) however wading is inadvisable if the water level is higher than a foot below the top of the bank, in any case a wading stick is recommended in these conditions.
Again start on the bank and fish down. A long cast in these conditions is not really necessary as often the fish will be travelling about a foot or two from the bank, continue to fish down until you reach the end of the bank. Take care at the point where the bend in the burn is closest to the river as it has been eroded during floods and is getting narrower every year.
