Lake Travis water levels are extremely low but metal detecting is not allowed. I guess that takes care of Lake Travis. Don't know about the other lakes in the area. HH
I was wondering why you can't detect at that lake. I would think if you can't detect at a park, you could detect below the water line as it is not part of the park.
I feel the same about core of engineer lake in State parks,, you can hunt a corp of enginnere parks so why not as long as your in the water cant you hunt in state parks.
see second lnk to the no metal detecting rule for Lake Travis
