Pond Boss Forums Thread Like Summary - New pond on a live spring

I plan to build a pond on a live spring with a constant flow of about 50 gpm in a 20 ft deep ravine and I'm concerned that that flow will be a problem during construction. A temporary dam can be built at the head of the pond but 72K gallons of water every 24 hours seems like a lot. I don't see how the spring can be diverted due to the lay of the land. I guess a pump with a long (100 yd ?) discharge hose could move the water past the pond site? Do I have a problem and what can be done about it?

My pond is complete and a small temporary upstream dam kept the water out.

Depending on the Spring water temp, you might be able to have trout all year long if the water temp in the upper pond is below 70°F all year long. Cecil keeps trout alive all year long with 50 gpm into 1/2 ac pond, but the ground water temp here is 53°F.
