Just tripped over this thread.
GEOTHERMAL. By Geothermal I mean that you have a continuously self-replacing heat sink to use a high-efficiency heat pump with. All that water could flow over coils looking to either suck heat out of the ~60 degree water (during winter when it is far colder than that outside), or to dump the heat pulled out of the house into it during cooling months.
It's really better than what most geothermal systems have - they are usually using a set amount of earth as a big heat sink - your heat sink gets replaced all the time.
In all seriousness you could slash your heating and cooling bills (especially cooling) tremendously.
If you can't afford a heat pump etc - if all you did was to pipe the output through a radiator block that you got for cheap and blew air through it during the summer, and let the water back out again - free cooling using NO pumps or compressors!
You can't beat that with a stick.
THEN I'd take the output and keep a good poly cistern full.
THEN I'd use the overflow from that and have a lovely waterfeature.
THEN I'd run the pond runoff over a narrow, rocky, artificial stream over a liner down to the nearest creek.
2-3 gallons a minute won't make a lot of electricity btw. Enough to maybe power low-voltage landscape lighting perhaps.
