Thank you Todd and Pond frog, We borrowed a boat to use until we can find a used one. we actually made a rope thing to corral the DW and it works well but getting it out once we get it to the bank is very hard. we worked at it all day yesterday and today the pond is covered again. I have been reading a lot about getting control of the weeds and we are considering herbicides but dont want to cause a major shock. do you think we should wait till spring and get them as they emerge or maybe do some spot kill in the fall? I was also wondering about dyes would that help control the DW? and with the spill tube constantly running would we lose the dye?
