Fishing spiders in moving water is not too tricky. Find a nice riffly run. Cast up stream and let it dead drift. The fly will sink and the idea is to let it get down a bit. As it drifts passed you, turn with it keeping your rod pointed towards the fly, raising it to keep the line between your rod and the fly "almost tight'. You're just trying to maintain contact but not move the fly (the current does all the movement for you). Extend the drift by flipping out some line if you have to. Then, when the drift ends the line tightens, the fly will swing up towards the surface. Try and time this so it happens in a location you think holds a trout. This "lift" often induces a strike. Then retrive some line back, pulling the fly up stream for a bit. Mind you, you will have strikes at any time in the drift, swing & lift, and retrieve stage, so just always be ready for it. I don't know what the fish think of this emerger swimming against the current, but the retrieve seems to be a high strike time as welll. I think the fish were following, and now strike as it's "getting away".

Anyway, try and drift through all the likely lies. Fish love spider patterns.
