Was reading a different forum where folks were having an in-depth discussion about who owns the water or beach area in relation as to whether we can water detect such areas. Searched here on the forum and found no occurrence of the terms for such laws, so thought I'd push these details out to the group for reference.
There are two "principals" or laws that govern the rules we should follow based on either Eastern or Western States. Wikipedia does a good job with the general details, and once you Google the correct terms you'll find plenty of additional details...
Wikipedia - Riparian water rights for Eastern States
Wikipedia - Prior appropriation water rights for Western States
For instance, here in Minnesota the State is governed by Riparian Water Rights, and the Minnesota Department of Natural Resources dictates that nobody owns the water adjacent to land owner property. As long as you gain access to that water area without trespassing on private dry land, you can legally go right on over to any water area right up to the beach and start water detecting without breaking the law, regardless of what a land owner on their property may "think". Obviously it's a good idea to not shed bad light on our hobby, but then again we don't need to be pushed around by the unknowing public as well.
Be sure to check your local and State laws regardless, as these laws vary widely. Sometimes adjacent landowners have no right to these water areas, yet some dictate that a pie shaped slice to the center of the water body is controlled by the adjacent landowner, and different yet some indicate that a certain number of feet into the water from the dry land property lines is what the adjacent land owner has control of.
Google up you local geographic details along with those terms above and you should be able to locate the "true" laws regarding your circumstances...
