It's 73 F. right now air temp. Surface water temp in the big pond exposed to the wind is 53 F. on the surface and 49.9 on the bottom. With the high winds I wouldn't be surprised if the temps got up to the upper 50's or even low 60's by the end of the day.
I turned on the diffusers to warm the water faster so I can get better feeding and feed into the fish faster.
