You can probably use a back/trackhoe to excavate close to shore, deepening the edges and leaving a steeper slope under the waterline so as to reduce the available habitat friendly to cattails. I have seen posts/pics of this being down with water still in ponds. I don't believe there is a major risk to the existing fish population; there will be some sediment introduced to the water column during such renovation, but if only one 'hoe is working at a time it will be somewhat limited.

I don't think shoreline work will have a major affect on DW.
