Our first snow this year was in September, we had a trace of snow in June which melted as soon as it fell. Snow is guaranteed from October through May every year. It looks like you have a lot more water than we do. Since we're the highest state in the nation, no water flows into the state, only out. Our water source is our snow. the lowest spot in the state is about 3,600 ft. on the border with Kansas. One of the quirks of living in Colorado is that everybody knows the altitude of where they live. What's the general altitude in Maine? I live at 5,600 ft. Have a great day.
