Whilst some necessary shortcuts were used to arrive at your figure, the water heated by far fewer air conditioners would eventually arrive at the surface thermocline. [And not be a 1° increase equally-distributed amongst the lake's 625 billion gallons]. Just 1° increase at the surface would promote Winnipesaukee's present algae and milfoil woes
earlier.
Why not use the mass of the Earth as a possible workaround?
Use well water instead of lake water, and call it "geothermal energy"—which I
think jimbob1603 may have previously referenced. The exchanged water could then be injected at a much greater depth than the supply well (Or below a suitably-deep "impermeable clay" layer).

That's a good one: New Hampshire
pays you to take their air-dried and compressed "milfoil logs" for the woodstove?
