Thanks for the information/suggestions. The cattails extend almost 30 feet from the shoreline into the pond. Do you think a standard backhoe would reach that far?

I have never had a problem with DW until this past year when the cattails limited the wave action on the pond. There were days when the DW covered the whole pond except for the 20 ft diameter openings made by my two diffusers. Do you think I am at risk for summerkill if the DW continues to cover the pond even with my aeration system?

I purchased some bacteria this past week and intend on using it to limit the nutrients. Do you think I should buy some herbicides to control the DW just in case?

Thanks again,
Kasey
