My favorite patterns for ponds are usually ones that will catch a variety of species. Rubber leg stonefly nymphs are very affective, especially on panfish and will catch their share of bass. For surface patterns, larger grasshoppers in sizes 6 and 8 will atract the attention of bass and larger panfish.
As for bass specifically, I love fishing poppers, and the ones that produce well for me are white sparsly tied ones. The white represents the beelly of the pray and a sparse tail adds movement to the fly even while at rest.
