I tried it off Big Pine...didn't get a bite, but got the technique.
you can use the same rigs, but depending on current and depth you may need more weight....a lot more weight. (maybe with light current and a good captn on the motors you can slow your drift down, but we're typically in the stream!) I only dropped 2 lines with my standard rigs (weights, lights and all) then used cinder blocks to get them down to 1100-ish feet. I used 20# mono to attach the block and once down gave it a real good pull to break it off (remember that mono streches a lot, and you have plenty of line out, so don't be afraid to crank up a bit to get the block off).
that pretty much gets your rigs down. then just drift as normal.
