Bar-K fence on Rock Lake -- when to be removed?

[KlausW]

If you want to reduce evaporation from Rock Lake, just stop the bubblers that keep the ice from freezing over and speed up the melt out in spring.  Open water surfaces evaporate way more than frozen ones.  Since many fish appear to die anyway, the main rationale for keeping the bubblers going may need to be questioned as well.  The fence did not help much with the drifting snow on Rock Lake road, did it?  Mind you we had a cold and windy winter (that is not quitting yet either), but below normal snowfall.  My 2c.
