Plant the plants shallow 12" to 2.5 -3 ft deep. This assumes the pond water level will stay full. Plant some even along areas of your steep slope on opposite shore of the stone ledge. They will colonize to depths and areas that they find suitable for growth. If you product clear water with visibilities to 8ft there will be enough penetrating light for plants to grow to 16ft deep. Usually it is at least 2X the visibility or Secchi disk depth.
