My buddy and I fish Aurora extensively year round, and we are both of the mind in the next few years this lake will have wipers of a state record size. The forage base (predominately crayfish) is absolutely amazing. Walking way back in Senac, I have seen so many crayfish it seemed as if the bottom was moving.
Fishing from the dam in the evenings during summertime we have seen schools of 12-16 pound fish cruising parallel to the dam no more than 10 feet from shore. These schools contain between 25-50 fish, all this size! Between this and seeing them start to boil in September, the visuals are incredible!
I think part of the reason they are all getting this size is lack of access. With a lake so deep and with so much open water (outside of the coves), they are very difficult to find. If and when you do, you can only go after them with an electric motor. So it will be hit and miss when you see these peeps, and I think that is a good thing. For me, it is part of the allure. You KNOW there is a monster swimming somewhere near you and there is a chance you will get spooled if you happen to hook him. There is also the chance you get to put him on your wall!
I have done best catching them with pumpkin gitzits back in LoneTree, but I have lost more than I have caught by at least a 2/1 margin. We have also hooked them trolling raps SUPER fast, and with bottombouncers also. If they are hungry and your bait happens to be in the right spot, they can be indiscriminate. They will take power bait, a worm under a bobber, etc. We all know trout are also a favorite table fare for them, and I can imagine them tying their napkins around their necks every time the baby rainbows are stocked.
