I would think the people managing the state lakes would raise or lower the limit if needed to keep the population healthy. when I lived in sc the limit was thirty and they have lowered it to twenty since I moved to alabama. Anyone in sc know why they lowered the limit. Was it due to fish population, lake health etc... With that said I'm sure all lakes are not the same. You would think it should be done by the lakes health and raising the limit or size for the entire state seems a little strange.
