Topband: Radials in the pond..?

[AA8R]

I'm putting out 60 1/4 wave radials for my 160m Inverted L on the 
ground.   4-5 of those radials will end up in my pond with anywhere from 
5-10 feet to 25 feet in the pond for those 4-5 radials.  The pond is to 
the NN/E of the Inverted L.

Should I:
   1)  Just attach to each radial a heavy enough weigh at the end of 
those 4-5 radials and toss the weight into the pond?
   2) Coil up those 4-5 radials and lay the coil wire at the shore line ?
   3) String those radials along the shore line?

Thanks for any suggestions.....
