Paul, most ponds are just accumulated rainfall, those with wells have it made ! If you can find the best of both worlds, ask the owner why he's selling ! Many times the price of a well equals that of the pond, it's not uncommon to pay 10,000 per pond or well. If you're seriously looking, the rainfall in your area has been generous so far this year, skip ANY pond that is not at or near capacity. There is no need for an alternative water source if you have a decent watershed area in Brenham...I can help you with topo maps once you pinpoint an area, that will assist with how your pond accumulates water. A general rule of thumb is that you need 10 to 15 acres of watershed area per surface acre of water.
