I put in a dry dam on the next draw over and ran a pipe to the pond to get more surface water. Works great and has solved my filling problem as it runs a full 8" pipe when a decent rain event occurs.
That led me to think about putting a small pond at the bottom of the dry dam and raise FHM for feedstock in my main pond. When rain event occurs the FHM pond would overflow into the inlet pipe to the main pond as the dry dam fills, then flows into the main pond. It looks to me the only thing I would have to do is dig a hole and construct FHM condo, everything else is already in place.
Questions:
How large a mini pond would I need to raise FHM without restocking or much care?
Do you think the water level fluctuation would be enough to carry a portion of the FHM into the main pond.
Am I entering the lunatic fringe of pondmiestering?
