Can you post a couple of close-up pics of the plant (or plants) showing its main characteristics?

Step one for weed clearing is to identify the plant. Fortunately, there are several experts that can help.

Step two is to hit the plant with the proper tool (either mechanical or chemical) after it has been identified.

Step three is to take small bites if clearing the entire shoreline is too big of a job. Maybe create a few weed-free lanes or pie wedges in your best fishing areas. With the practice doing those areas, you should be a more efficient worker as you move up to tackling bigger sections.

Congrats on the lake front home!
