Yep they did open up splitrock to fishing and people are always in there with canoe's and small boats. I know they set up a lot of gates recently that are padlocked. The security around splitrock is private but the local police has some racing quads that we have seen go into the woods. I have been just heading up north near layton. It's a little bit of a drive but It's definitely worth it and nobody bothers you at all. We actually plan on heading there tomorrow night with a couple trucks. Not sure exactly what time though.
