Fished the Yough from the dam to ramcat a number of times. Its been about 10 years since I"ve been there. Wait until the fall (Sept. Oct. Nov.). Water temps. getting back to normal. Have had many on that I could not Land. Some approaching 2'. If fishing nymps, you must get the fly/ flies bouncing off the bottom. The only way I could do this was tie a tag line 12" below droppers and add split shot. Also a staff for the river is a MUST. Ramcat was my favorite place. Always had the place to myself.
