I've witnessed the carp spawn at a local lake before and can't for the life of me remember when it was. I wasn't fly fishing at the time either. I was hoping to find it again this year but they drained and dredged the lake and I'm assuming things will all be messed up for a while there.
Carp spawn or do you mean sucker spawn?
Catching suckers gets old after a couple fish. They turn your leader into a gooey string of snot. However, some of them do rget pretty darn big.
On the other hand, I've never seem many carp in the tribs. A few, but not enough to make me want to go there to target them. But. I usually don't fish all that close to the lake either.
I know about the sucker spawn, I believe its close to being full swing by now. Had a gentleman tell me about catching carp up to 10 pounds in late April/early May during the carp run on Elk Creek. Was wondering if anyone tried this?
