Hope you have fun down there!
My first trip to ABC, was in mid-February. I didn't catch any at the Radio Tower Pond. But, then I caught four 12 - 14 inchers, at the I-5 Spillway on Power Eggs. And I wrapped up the day, by catching 6 or 7 more in about an hour, at the "outflow / spillway" pond. Got 'em all on Green/Orange combo Power Eggs n' scent.
I really like that place. I wish that we had a park like that in my neck o' the woods.
Have fun!
P.S. The locals (nwkiller, natro, and others) have said that there are also some BIG bucketmouths in the Radio Tower Pond.
