The picture could be taken closer to the plant to show more detail. From the picture it looks to me like sago pondweed. There are a couple other similar looking submerged plants it could be - all pondweed species. Normally when this plant is abundant the water is pretty clear. As it becomes more abundant water becomes more clear. The plant does have numerous benefits for the overall pond ecosystem. When the plant is over abundant and interferes with normal pond use, several options are possible.

If it were my pond, I would try to remove about 1/2 to 2/3 of it with either manual removal (lake rake or weed razor) and grass carp. Add grass carp gradually over 2-4 yrs so some plant remains. Having some plant still present is very beneficial for the pond and fishery. This plant depending on abundance competes against filamentous string algae (FA) and keeps it at less coverage. No competition allows FA to grow rampantly.

Thank you for the reply. The pond is right at .47 ac per google earth 12' deep . The fish truck is coming to my area at the end of September. They advertise 6-8" grass carp.. How many would you recommend??

You don't want the grass carp to denude the pond. Start gradually with adding the GC. Number to add depends on how much of the pond bottom is covered by the plant. If the GC eat all the current plants the recycled nutrients will grow another plant, likely filamentous algae (FA), the GC will not eat or eat it very poorly. Then you have another problem that is often worse than the original plant. Allow around 25% of plants to survive. You will not know how well the GC control the plants until after 2.5-3 yrs and the GC are 24"-28". GC are known to eat 3X their body weight per day when water is above 70F. I would start with 2 fish. Then after 2 yrs you still have ample weeds then add 1 or 2 more. Make sure they are 1/2 the length of the largest bass or they will be expensive bass food.

I run into this problem frequently when I am called to stock Triploid Grass Carp in peoples ponds.

People say "The fish truck stocked 6"-8" fish but I never saw them/" When I explain to them how they have to stock Triploid Grass Carp that are at least 1/2 the length of the largest Largemouth Bass in the pond or they'd most likely end up as expensive LMB food they reply "Now why didn't the fish truck guy tell me that?"
