A 10 pound northern strain bass in TX is reasonable if the right conditions are present... I would say yes, there is a high likelihood, you have at least a few double digit bass in your pond so smart they are near impossible to catch. Try a live BG in the 4"-5" range on a 2/0 circle hook with no weight and live line it... You may shock yourself at what you catch...
I would look into stocking threadfin shad next spring if growing big bass is your goal... Consider an electroshock survey, which will tell a more accurate story. Hard to grow double digit bass without at least 1 species of shad present. If 25% of your bass are over 16", consider the risks which there are plenty... But, you can also consider gizzard shad. I would try the threadfins first though.
