National news has mentioned the Needwood earthen dam is in jeopardy.
Thousands have been evacuated but so far we have had no alert.
At the end of Oriental St. in Aspen Hill the dam channel is about 200 yards away and 45 ft lower than our house.

Thing is, the dam is 80 feet tall and 2.5 miles away. There is still no information on my immediate area and have had no evacuation orders.

I'm wondering if a GPS unit would give me clear elevation data?
