We're probably within 15-20 miles or so of each other. Our property is north of Lampasas and south of Evant. Your stock tank is similar to one of ours (one of our dry ones). Is there any chance you have clay somewhere on your property to seal the tank properly? I noticed that with one of our tanks, it looks like they dug it out and then tried laying a thin "skim coat" of clay (optimists??) so it makes sense to me why you were told that your tank needed to be re-clayed. I don't know if it worked initially but with the drought and all, our tank is in really bad shape (will need to be redone properly). Also, you may want to check with
http://acme.com/planimeter/and check the topography map to confirm that you are capturing all the runoff. When I checked our land, the water was indeed running down the hill but it jogged due south of the tank! If you're going to have work done anyway and the funds are available (and depending on the topo), you may want/need to have some regrading done at the same time so that you can capture all of the runoff possible. When you say that you have soil at the bottom of your tank, is it silt or ??? The guys here have been really helpful in teaching me about sediment/settling ponds, too.
