When we think about water management, we think about reservoirs. What we're really talking about across the west is snowpack. You know we think of reservoirs as physical things, but dams are really structures to manage snowmelt. Winter storms coming off the Pacific Ocean have to be of a certain nature. They have to be cold enough. They have to have enough moisture. They have to be able to tap into enough moisture to be able to put down snowpack at upper elevations. Those are really critical to building up water in the reservoirs.
