I fished here once last year.
I payed about £7 for a day ticket from I think it was from Gee Tee Angling in Silsden, or I may have bought it from K L Tackle in Keighley.
It is a lovely reservoir which holds some decent fish. There are Rainbows and Brownies and some large Perch in the water.
You can use worm, fly and minnow.
I used wet flies, these were Wickhams Fancy, a beetle, Black & Peacock Spider and a few PTN's. I also used dry fly when there were some action on the surface.
I lost some small trout, most likely brownies on a red ant
see here for picture.
Some one told me that if you go past the stream that runs into the reservoir and fish where the rocks are, then you will find the Perch.
I haven't been since.
