Well that's very pretty! I'm guessing the problem is too much of it?

Bag it up and give it away for cost of shipping on here!

It appears to be an invasive plant, which means it’s probably banned in a lot of states.
According to one source at https://www.invasivespeciesinfo.gov/profile/curly-pondweed:
"Curlyleaf can be managed using mechanical methods, herbicides, and habitat manipulation. Since curlyleaf is generally gone by mid-July, management activities should be undertaken in spring or very early summer to have the maximum benefit.
Mechanical control includes raking, cutting or harvesting vegetation.
Raking and hand cutting generally remove the plants at the sediment surface, while harvesting generally removes the top five feet of the plants.
Mechanical methods control plants in the specific areas where they are causing a nuisance, and there is immediate relief from the nuisance. There is some evidence that early season cutting of curlyleaf at the sediment surface can prevent turion production (McComas and Stuckert, 1996). MnDNR Exotic Species Program staff monitored the results of this type of cutting in French Lake (Rice County) and Weaver Lake (Hennepin County). It appears that cutting is effective in removing curlyleaf in the cut areas, though annual cutting appears to be required."

This is a highly problematic nationally-recognised invasive species in the USA. Potamogeton crispus can outcompete native species for light and space early in the growing season reducing plant diversity.

It's at the top of the list at https://portal.ct.gov/DEEP/Fishing/General-Information/Aquatic-Invasive-Species:
The importation, transportation, sale, purchase, cultivation or distribution of a number of invasive plants including the following aquatic plants is prohibited*:
Violators can be fined $50 per plant! (CGA 22a-381d)
- curly leaved pondweed (Potamogeton crispus)...
The thing about that method is that if you kill all the plant life, suddenly you have a massive amount of rotting plant matter to deal with. When you kill off a ton of vegetation suddenly, the dissolved oxygen (DO) in the water drops due to plant matter dying and decomposing, causing fish to suffocate.
