I have recently read magazine articles that recommended having eight to ten feet between flies. I have also seen nine foot leaders with two droppers. What is the minimum distance you would have between flies for still water bank fishing?

It all depends on the fish, conditions and what you are trying to achieve.

When fishing the washing line, often the most important nymph is the one closest to the booby. (fish are attracted to the disturbance the booby causes then take the nymph closest to the booby)

Also this can occur when fishing the Bung -fish are attracted to the disturbance or sillouette of the bung and take the nymph closest.

I have in some instances fished a nymph 2.5ft from the bung or booby...although usually it is a size 12 nymph.

For Lure fishing I still prefere 6ft to my top dropper, then 7ft to middle dropper then 10ft to my point.....(long handled net required)

Or if it's very windy and I'm pulling just 2 flies 6ft to the top dropper and 16ft to the point

No hard and fast rules, just depends upon the conditions and angling pressure the fish have recieved.

I have tried every combination over the years and this is my starting point from the bank with floating line , I use a 13' level leader with 1 dropper 5' from the point . Use a shorter leader with sinking line , dropper spacing the same .
