I'd look for any natural riffles and/or pools. At Nugget Lake, I'm on a straight stretch of shallow rapids that drops into a shallow pool. The gold follows the left side to middle (looking upstream). My first hole there was a large rock with a sand trail into the pool where the current would slack. That tail was yielding about 5-10 colors per pan. Going upstream from there, the color continues.
I'd first test in a line across the stream to figure out where the gold line is, and then work upstream from there. If there is a pool, work on the upstream side first using the pool as a safety pan. Then go back and hit the pool to catch what your gear might have lost. Someone sluiced into my first hole at NL, and I pulled some real fines out of their tailings. Once I'm done working upstream, I'm hitting that pool and dumping my tailings in the hole on the downstream side.
