Pond Boss Forums POND CONSTRUCTION Renovating a Pond or Lake? No water in my central texas pond ?

My place is not too far from Lampasas (Kempner). The tank is basically dug into the lower 1/4 of a very big hill so it's getting atleast some watershed. The bottom of the tank is full of soil and green grass but the walls are all gravel/sand/big chunks of Texas limestone rock.
