Does anybody have an idea where the best place to buy or get clay around brownwood, texas? My dilemma is this. I had a pond dug over 4 years ago and it has not held water for extended periods of time. My contractor feels like the soil needs more clay in spots and we have now found those areas. I have looked at purchasing Texas sodium bentonite out of Comanche but would like to find some clay that I could purchase first. I am having a difficult time finding it and I looked over the 2,000 acres around us without success. Any ideas? Thank you.
