I've fished here many times below the falls, under the old Roman Bridge and down into the deep gulley leading to Dunning Glen, but don't try that now, not without scuba gear because all of that racey little section of the river Devon and a bit of ancient history, an old roman bridge, were flood out when the Castlehill Dam was build to create the reservoir. I've fished the reservoir too, it was a bit dour on the day and I suffer from vertigo. On the day I took the photographs the water was cascading over the the dam creating a spectacular waterfall and just knowing that drop was there left me feeling queezy, weird or what?
The loch fishes well for brown trout and rainbows, there are also some very big pike and perch. Where the pike and perch came from someone knows because they put them there, naughty. There were none in the Devon when it was flooded.
If you go to the dam and look over you will get a fair idea of how deep the water is in the main body. I remember the glen was steep wending up to the narrows where there was a long section of rapids flowing from the falls up by the bridge. I recon it could be cosy up there in a boat now.
There are boats available while bank fishing can be limited by the steep banks and bankside vegetation in higher water.
