Paulina Lake was also good for me and FFP guide Steve this week. We both found beetles to be really effective, and he was using an ant. I tried with a pink hopper for a while to no avail, and when the other angler in the boat continued to catch on a jiggy beetle, well, it was time to tie on 2 of those. 
I also found some quality indicator action on black double down nymphs (essentially a dark assassin) and with red 2 bit hookers and watermelon leeches.
