Big Fish Just Won't Bite

[Scott]

I was fishing a local res. one day when I saw a couple of small ponds, almost like drainage systems over yonder. I saw it was really shallow and grassy. Maybe 3 ft. at the most. I threw a 4" worm in and caught about 20 small bass in about an hour. Today I went back and it was really small, and saw two really huge bass about 5ft. off shore. I tried throwing everything I had at it and it just kept swimming back and forth over and over again. Water clarity is very clear. Any tips on what I could use or try to catch it with? It almost looked like a small pike, but i couldn't tell? Thanks
