Depends on what "carp" your looking for. I was at my hunting spot opening day of turkey season (06APR08)and the carpsuckers were already moving upstream on the high water (I hunt in the far NE corner of Oklahoma). Didn't manage to get a bird, but did fill a 5gal. bucket with sand bass. Squirrel season won't start here until mid May or I could try for a real fur, fin and feather trip. We have had a lot of rain, keeping the water temps low, but I think most fish that move up stream to spawn are more influenced by water level and photo period.
