There is a well known duck hole here in central alabama off the river that has been hunted for years. The hole is accessed by the river and it always has water summer and winter. Well this year the land owner took a dozier and pushed over several trees across the entrance to the hole right off the river. First off is this legal for the land owner to intentionally block a navigable waterway like that? Second, would you take a chain saw and cut the trees where you could get to the whole? Thanks for opinions.
