I have a freshly excavated pond:

-spring fed (cold water always flowing in even in summer)
-average depth 4 ft, max depth 8 ft
-remains open without freezing at inflow and outflow (good aeration)
-about 25 yards wide by 20 yards long
-location in the Adirondacks of NY
-zero fish life in it now

1) what would be the best species of trout to stock (fingerlings)?
2) what are 'compatible' trout species to stock?
3) what would be an acceptable number to stock in this size pond?
4) what other considerations are important to establish them?

Thanks,
Rich
