Fished in the Keystone fly project near Wharton yesterday from 1:00 till 2:30PM. Sky was overcast, air temp 49, no wind, water temp was cold, (sorry I need to get a thermometer, new member). Water was clear but high and moving. USGS gauge at Wharton was 504. (it's 420 today May 12). Usually a good stream level there is below 300. It's been steadily coming down from a peak of 1500 cfs on May 6. I was the only fisherman in the stretch I fished and I saw only 4 other cars in the rest of the project.

I saw no rising fish and possibly only one mayfly on the water, it was against the far bank and I couldn't ID it but was a good sized fly, possibly a March Brown. A second hand report was that Gray Foxes were hatching earlier that day.

I was swinging a march brown soft hackle and a picket pin with a lot of weight and surprisingly caught a 17 inch fat rainbow on the pin. That was one of only 2 strikes during the 90 minutes I fished. I was there a week earlier before the storm front came thru and caught 3 big bows using similar flies. Stream flow then was about 220. God bless the Keystone project!
 
Aren't Grey Foxes just March Browns? I never thought there really was a real fly called a Grey Fox...just a version people tied.

to the best of my knowledge grey fox is just a fly pattern not an actual insect
 
The Gray Fox was originally classified as a separate species, Stenonema fuscum. It has since been reclassified as a March Brown, Maccafertium vivarium.

Two common color variations of essentially the same species... If the lighter variety is found on a particular stream, I would use a gray fox, not a march brown.
