I'm doing a 6 day Backpacking trip and was trying to pin down a few good springs for drinking water. What is the most accurate way of finding out this information without actually being there? I talked to the Forest Service but never recieved any staight answers. They told me there was an abundunce of water everywhere and all the streams are flowing full. I even told them the exact location i was going. Any other ideas would be helpful, Thanks.
