The pond has a large percentage of shallow water and very likely clear water due to a large amount of naiad growing. Bottom growing plants tend to promote / produce clear water. Clear water allows good light penetration deep into the water thus allowing lots of bottom plants to grow. Knowing this why would one not expect to have a lot of bottom vegetation? Long term fix IMO - deepen all the areas less than 6 ft deep. Dyes help reduce light penetration in water less than 3ft deep. Plankton algae blooms also are often used to reduce light penetration. Plankton blooms can be 'tricky" to get established and to maintain for the long term.
