I’ve been driving across the Roosevelt Bridge most days to head into the city, taking the exit for Independence Avenue on my way to the Hill for some coffee and wireless internet. Every day I cross over that bridge, I see the level of the Potomac and I wonder why it’s so low. I recognize that the Potomac is on a tide schedule, but I don’t ever managed to see the river at high when the water line is anywhere near where the historic marks on the masonry sit.
Does this mean the Potomac’s a bit low? I know it looks like it’s down about 4-6 feet, judging by my optical guesswork, or am I just imaging all of this in the midst of a consistent debate on global warming?
