I do need to think about some bottom structure, but nothing that will eat fishing lures...
The most lure-friendly structure is "stick-ups" made from floating poly pipe. Cut 3/4" poly pipe into 2'-4' lengths (according to the water depth). Plug 1 end with clay, and it will cause the pipe to sink and stand upright on the pond bottom. A group of 20-40 make a nice little artificial weed bed, with no worries about snagging your lures.
