ZZ,
Fish relate to "edges"....you can spot various edges & structures by changes in surface chop, water color, water clarity, etc. Any change in appearance on top of the water relates to change subsurface. Other edges can be very obvious, such as visible brush, weeds, docks. If there is significant shade on a shore, especially with the wind blowing in, try that as well.
In a bowl shaped pond, Rick is right on the depth & a good "search & destroy" fly for me in those type waters has been a small Black Ghost streamer....takes gills, crappie, bass.
Good luck & please keep us posted.
Mike
