Big Horn high water technique is to take a 6 oz bell sinker and put it on ""ought" x tippet...run some droppers with big nymphs and some with little nymphs off that main leader but on 12 inch tippets of 4x ...this was invesnted by guides to use when BHwater was totaly unfishbale from high discharges but the guides realy needed the $400 a day to survive and the clients were there and wanted to fish, so why not....anyway it is a fly rod equivalent of a drop shot as you put this bell sinker on the bottom and lift and drop it , like jigging, in foot long vertical pulls....take a lot of beer.
