The dive may also find items Bryce threw into the water if he wanted to go missing. Remember that one of the scent trails went across the top of the dam.
I know we had so many discussions in the past about the possibility of him being in the lake itself and for me personally, I still feel its very possible.
I've just read of too many stories where a body stayed submerged. It could have gotten snagged on bottom or wedged between 2 rocks. I know there were previous searches of the lake but I have also read of other examples where searches just missed finding the person the first time. It is very difficult to find bodies underwater sometimes so I can easily see where he may have been missed.
Unfortunately it takes time and money to do new searches of the lake and its surrounding area but if there were funds available then I do think it would be worthwhile. And for me personally, I would begin in the lake itself again.
My reasons are nothing more than a hunch that perhaps when he got injured he walked into the water to get relief from his injuries. I am thinking he was under bad pain and so I think he may have waded out into the water just to get the cool relief of the water. At that point, I think it got deep over his head and perhaps he was so injured he couldnt swim well enough to make the shore again. Or his wet clothes impeded his ability to swim back to shore. People sometimes do not realize how quick the slope drops off when entering water. If he went out around waiste deep, then you can sometimes take just 1 step more and then drop in over your head if the slope was very steep depending on where he may have entered.
My understanding of that particular lake and especially the dam area has the slope dropping off very rapidly. I recall seeing TOPO maps that seemed to show a very very steep slope on some of the banks his vehicle was near. The dam area especially would have a steep slope. But even near his vehicle seemed steep in a couple coves.
And dont forget when walking in a lake, your footing underneath is probably rocks or muddy slippery spots so your footing is very difficult because you cant see what you are walking on and you can easily slip off what you are standing on.
Then I think his body sunk down to a relatively deep area and with boat currents moving him even further out till he got lodged between some rocks where it would not surface.
I hope I am wrong and he will just show up someday happy and healthy but as time goes on, this type of scenerio becomes more likely to me and its just too bad that there is not an easy way to prove one way or another he may be down there. Or like others mentioned, perhaps just in surrounding area and somehow has remained hidden.
