Weekend

Few days late but Sunday headed to the Allegheny river and fished it at my highest it was about 12' at the LD I normally go to and a gentleman was telling me about 20"+ walleye in the crooked creek outflow, and I was thinking to myself he's crazy or just telling me stories... Can anyone confirm or deny this and if it can be confirmed I assume it's during high water instances and i'm wondering if anyone has a relative idea of a good "high water" time for the outflow cause as of 9:45pm EDT today (5/9) it's at 1830 CFS which is um... Probably nasty high making the outflow almost unfishable or even unable to be accessed...  Any info would be great i'm heading out that way this weekend and may try up there if the river is much above 12'...
