IMO you should be looking for 6"-8" LMB - some 10" if they have them. Keep in touch with Keystone hatcheries and Nate Herman as to their status of larger bass (6"-10"), often avilability changes in the hatchery business. YOur pond could have had a partial winter kill or numerous spawning failures due to over crowded sunfish /BCrappie to the point of eventually eating all the bass eggs and fry during the past 4-6 yrs. Thus as LMB died &/or were harvested few if any new LMB were recruited leading to few bass and over abundant smaller fish. 7 ac is quite a bit of water to get back into shape - 'balance'. It will take a quite a bit of effort and expense to manage it back into balance. Expanding it to 12 acres will not make it easier to manage.
