The proposed pipeline appears to cross the Potomac near the mouth of the South Branch. It's hard to determine from the tiny map shared by the gas company whether it crosses the South Branch or travels east of the river to Levels.
The terrain map below shows that there are possible routes along the North Branch floodplain, French's Station Road, or along the South Branch meander that creates the French's Neck West / Blue Meadow's North floodplain.
This seems like an opportunity for planners and our government leaders to negotiate a better bridge crossing at Oldtown/Green Spring, or possible road improvements wherever the pipeline travels.
The line of cars waiting to enter Great Falls Park grew longer as Saturday morning progressed. Many people wanted to see spectacle of flood waters rushing and exploding over Great Falls after our recent heavy rain event. At one point on Saturday, the National Park Service posted that the wait was one-to-two hours to enter Great Falls Park.
I arrived early, before the crowds, and the sound of the falls immediately greeted me as I stepped out of my car in the park’s parking lot. When the Potomac River floods, Great Falls is loud. The sound is impressive.
The flow rate of the Potomac River at nearby Little Falls peaked at slightly over 150,000 cubic feet per second on Saturday. The median flow rate is 10,000 cubic feet per second. I have included a flow rate chart and photo comparison to show the difference in flow rates from near normal levels on the river and Saturday’s flood stage. The photo comparison also shows the contrast of seasons at Great Falls.
Potomac River flooding to the level we saw this past weekend is not too uncommon. On October 31, 2012, the flooding from Sandy was comparable, perhaps slightly less. Here’s a photo post to check out Sandy’s flooding of the Potomac. Here’s another post showing a flood from February 4, 2013.
