I got out after sunset last night at one of my go-to spots in the general area of the Pentagon. I must have beaten the dirty water, because it was clear and there were plenty of fish around. I felt a few herring bump into my legs, caught a 14" striper on a 5-6" long fly that looks a bit like a herring. Every few minutes i'd see a schoolie blast something on the surface, but I had my sinking leader on so I couldn't tie on a popper to take advantage. downsized to a clouser before leaving and immediately caught a 13" crappie. I am wondering if I return tonight if the muddy water will have filtered in?
There are a number of gauges along the Potomac, but here's my favorite: https://waterdata.usgs.gov/usa/nwis/uv?01638500
As you can see, it's about 2 feet above it's historical median right now. As long as we don't get any significant rain over the next few days, I think the Potomac should be fishable by Sunday at least.
