Narrative:

On the river visual 19 into dca I was pilot flying. Abeam the georgetown reservoir I got a little low as the altitude recommendation slipped out of my mind. I was between 1100 and 1200 feet when we got an obstacle caution. I corrected by pulling up and climbing 100 feet. The caution extinguished and we continued the approach in visual conditions.
