Junction is a very dry area, if it's only 100 circular feet, you will need supplemental water, or a very deep hole. A liner could be easily damaged as the water levels recede.
My advice would be to wait until you get enough dough to bring in a dozer for a good sized 1/3rd to 1/2 acre 20ft. deep pit...it's deep enough in your area to hold water and last year round...providing the test holes produce some clay, which they should. If you have a decent runoff area, 4K will get you the catfish hole you're looking for, and keep the wildlife happy. Heck, throw in some CNBG & a few LMB too
