I know it's not where you were asking about but the hatches can be similar. I was there in the evening. There was a pretty good PMD hatch coming off early as well as a bunch of caddis, especially later. If you're not seeing risers, shoot for small nymphs of those variety. Also, sow bugs and midges are always a good bet. There should be decent dry fly fishing for periods during the day and especially right at dusk too.
