Just wanted to update on the progress. This first picture is basically what I was dealing with. The torpedo grass was extending out pretty far, all matted and thick across the whole bank.

This is what I cut back so far using the lake razer and a rake.

I've gotten a lot of the muck buildup out and like the improvement. I guess I'm wondering what else can I do to limit the grow back? Now that I got a lot of the buildup, should I let it grow back a little and target the plants individually as they pop up?

The lake razer doesn't cut all the way near the bottom of the grass as you can see in this photo

I bought the Midwest lake rake which is a double serrated blade, but that thing doesn't work well at all on grass near shore.
