So far my 4' x 20' walkway is only anchored to the shore. It is subject to moving laterally back a forth, but not too much. It will also seem unstable at times. I've used 8' poles on the corners, to stabilize it, but didn't like those either. My hope is once I put in another section "T,ing" off the walkway, that will cure the stability issue. I may put in the poles again at a point on the walkway where they won't stick up too far. Once up above a few feet, they become perfect perches for the kingfisher to wait in ambush.
I was trying to avoid the cables, because we swim in the pond so often, and they are not fun to swim into.
With your water level fluctuations the poles aren't applicable, you may have to use the cables described above by esshup.


9 yr old pond, 1 ac, 15' deep.
RES, YP, GS, FHM (no longer), HBG (going away), SMB, and HSB (only one seen in 5 yrs) Restocked HSB (2020) Have seen one of these.
I think that's about all I should put in my little pond.
