I think Texas has a lot of advantages that other states may not have. You can do most anything you want if property rights and state rules are followed.
When we built our puddle, the dam turned out to be 1050'. There were no issues or permits, but we were careful to have the overflow go directly into the existing creek bed, and cap the water at the top of the property so it wouldn't back up into our neighbor's property.
Other than that, we could have built the lake 3' inside the property lines if we wanted to.
