I haven't been up there since this last snow, so I'm not sure today, but worst case you can drive to bottom of damn and snowshoe up the road to the top of the damn, it's a couple blocks maybe half mile worst case. Last time the snow cleared shortly (couple days) after, so within a few days I'm pretty sure you can drive to top of dam at a minimum, but most likely you can drive back in to the top of the reservoir as well, but this will be storm related and the closer to the storm, the tougher it will be to get in there. I'm thinking with serval storms this week, it will be tough next weekend, but that's a total guess... Thinking about trying it Friday possibly myself, but not really sure what my plans will be yet... Good luck... Jeff
