Pottsy, pond still in planning stage - primarily for limited to moderate livestock watering (we call them tanks here)
Since we have a healthy 2 acre pond for LMB/hybrid striper with bluegills, thinking more along the lines of forage for main pond.
It will be located downstream from the main pond.
Don't know about depths until further along with the planning but probably only deep enough to survive our hot summers and prolonged droughts.
