They've had water rights from Haystack since they sold it off a few years ago. What they got this year was the ability to use an EXTRA I believe 18 million gallons(or some amount close to that), over the course of the year that previously just sat in the pond next to the entry for Haystack.
Mount Snow's entire pumping system is connected. If you were to drive down Handle Road (the road that goes from Carinthia to Haystack), there's a big supply pipe burried on the West Side of the road that connects Haystack's water to Mount Snow's system. Then once it gets to Mount Snow, the pump house/ snow making building that's off to the left of the Nitro Quad as you look up at the mountain from the parking lot sends the water up the hill and into the system, and depending on what valves are opened/closed the water can end up on any snowmaking trail on the mountain.
This already existing pipe between Haystack and Mount Snow is a component of what would be the final pipe/pump system for the proposed West Lake project, although the town of Wilmington wants the ability to use some of it for fire hydrant purposes.
Thanks for the info. I wasn't sure if they had the mountain split into different zones that couldn't be easily connected.
