HSB aren't an option in VA as they are illegal to stock. Just FYI on going that route...

If you can source pellet trained SMB I'd say they may be as good of an option as I can think of for what you are trying to accomplish. Good luck finding them in the mid Atlantic area though, we aren't exactly blessed with a large number of fish hatcheries to choose from. You can stock non pellet trained SMB, however I would attempt to keep them from having much success in spawning. This should prevent them from becoming too abundant and over eating their forage.

Speaking of forage, you have a new pond which means you have the golden window to establish a well rounded mix of forage species. Be patient in stocking them and you'll reap the rewards. Stocking SMB over LMB will mean you have a better chance of having at least a few species of forage naturally reproducing in your pond, particularly if you keep their numbers in check and provide good habitat for your forage fish.

Forage species I would highly recommend for a SMB pond in northern VA would be:

fathead minnows
bluntnose minnows
banded killifish
spotfin shiners
satinfin shiners
golden shiners
tessellated darter

If you decide to go the LMB route and not the SMB route, then your sunfish(BG/RES) will be the backbone of your forage as the LMB will almost certainly remove all the other non spiny forage fish. If you go the SMB route, I would skip the BG and only stock RES with possibly some redbreast sunfish. SMB struggle at best to properly control BG reproduction, even LMB struggle to control BG reproduction here in northern VA.

Skip the threadfin shad, they will not over winter in northern VA. Do not stock goldfish. They will make a muddy mess of your water and don't eat aquatic vegetation. If you can source a safe crayfish species, they would be fine to stock. Just understand that some crayfish dig holes and can damage your dam. If you don't plan on eating catfish and don't have much interest in fishing for them, skip them. They'll just compete with your bass for limited forage a 3/4 acre pond can produce.

In northern VA, it probably will be 3 and more like 4 years before your bass hit 14". Even with good forage. We don't have nearly as long a growing season as the south does... That is why a 6 lb bass is big around here! Research the forum... Understand how to measure and weight fish and keep track of relative weights. Do forum searches on SMB to decide if you want to go that route. The one nice thing about SMB is if you do decide on them and later don't like them, stock a few LMB and within a few years they'll be gone and you'll have a LMB pond.

Hume is a beautiful area, you can see that in your photos. Best of luck! Read up... There's lots to learn here in the archives and by doing searches with key words of interest to you.
