Oil Creek Memorial Day weekend

Planning a trip up that way Memorial Day weekend.  Will be fishing East Hickory and want to give Oil creek a go.  I have never fished Oil before any information on what hatches are usually on Oil around that time and how are the 2 DHALO areas to fish would be greatly appreciated.

Good mayfly hatches but I've found you just can't go wrong with a muddler minnow. Poor water conditions last fall should allow a good holdover of trout west of Petroleum Center.  

southern trout
How is Buffalo Creek?? Thinking the traveling the 2end week in June. Are the Fish big and easy to catch with the warm water? Rapalas or flys?

Buffalo on the Butler/Armstrong line? There should be some fish. Its part of the Keystone Select waters, so PFBC and local club adds some good size fish. Just use whatever trout lures you normally use.

Buffalo creek can be a lot of fun with soft hackles in or near the riffles.  The water can get a little warm in summer but can be good early morning and late afternoon/evening.  I haven't noticed a big mayfly population but lots of caddis and midges.  It does get hit hard being so close to Butler and Kittaning but has a lot of fish and occasionally have seen a beaver prowling around (NO NOT THAT ONE).   Black soft hackles and wets always seem to produce good throughout the day.  Good luck southern trout.  Oh one more thing It has a silty bottom in a lot of places so lace up your boots tight, thought I would lose mine once or twice lol.
