Concave Dam Lake
Play the game at least 50 times to unlock the dam
Increase the size of the fish you catch (in and out of tournament mode)
After selecting a lake (non tournament) the lure screen pops up for you to select a lure. Choose the lure you want, and at the same time press the Triangle, circle, X and square buttons with the R1 and R2. (same thing in tournament, except the instruction diagram and text don't appear.) good luck and good fishing!!
