Freezing Temperatures in California & Elsewhere - Protecting Plants, Animals and Fish

Hello all,
 
Anyone have advice on how they protect their borderline plants?  Freezing temperatures are expected in California for the next week or so.  I am covering my tender plants with sheets and blankets and wrapping my outside water spigots and insulating my well better.  I''m also keeping my cats inside at night (do anyway because of coyotes and owls).  
 
I have heard about floating a log in ponds with fish will keep it from freezing solid on top - does anyone know about this practice?  I have a sunken bathtub with some small Koi and so far they are doing well - I don't want to lose them - one has doubled his size this year from 2.5 to 5 inches. 
 
Thanks.
