Slippery rock white fly hatch

[Wishfishingpaid]

Hi all,
I'm new to fly fishing and was wondering if anyone had any info they could share about the white fly hatch that happens on slippery rock creek. I'm hoping I'm not too late, and being a new father I don't want to/can't spend too many evenings on the creek if it is over or hasn't started! I've fishes sr a few times near 79...does the hatch come off that far north or do I need to Try closer to McConnells mills? Any advice would be greatly appreciated!

Thanks!!

Plan to stay late. It should be coming off anytime now. When it does, you will know by the silence.

It is usually winding down by now. It is reliably the first week of Aug. There are still bugs but the best is past IMO.
