I second the furled leader suggestion. I use a furled leader almost all the time, but I feel they truly excel in these conditions.
I also use the "bow and arrow" regularly on small streams.
the third "cast" that I find helpful I refer to is a flick cast. I'll below and off to the side of the pocket I want to fish, with the rod out over the water and the line downstream, in the water, and just 'flick' the rod to propel the fly upstream, keepin the line and fly close to the water and under any vegetation.
