We have an active artesian well on our property. It drains off into the
local lake in a 2" pipe 24X7X365, winter, summer, etc.

I would like to build a pond and water fall system and use the artesian
water to supply the system.

Questions:
Water is about 55 degrees, is this too cold to support plant and fish life?
With this steady flow, I should not need a pump or filters (right?)
I would like to drain the pond into the lake.

Probably could raise trout in the pond you create. Your local DNR will
be the ones to ask, if the water runs off your property.
