You are so lucky. We don’t have enough area to have a fish pond here.
Lake Travis is a flood control lake that is 62 miles long from dam to dam. It has areas that are almost 200' deep when full. Right now, it is about 30% full and dropping daily. We need a flood to fill it again. Last two floods, Austin was lucky it was at a low level when the floods hit, or it would have gone over Mansfield Dam and flooded the lower parts of the city.
I have two stock tanks on the land I own about 80 miles from my home. I can go there if things get bad here, and live off the land. I just need to start a garden there and visit it more often.
