hi if you contact the core or engineers they most likely have records of those plots and sales. there is or used to be a small office beside the post office, it was or is for farmer that sign up for subsidies from the gov for farming. they used to have records and Ariel photos of all the plots of land in the country or the county tax office might still have those. i think that took place in the 60 so that is not that long ago in terms of how long they keep records. i remember a lot of farms were and i think some home sites were covered with the water. but i would first start at the tax map office that man has a lot of records or he used to. and then the office beside the post office. they may have the Ariel photos, you may just have to dig for them a bit.
