Welcome Webbster, I see you are from Boonsboro that is where I grew up. I currently live in Germantown.
Been awhile since I fished the spots you list, I would take a look at Big Pool (in Fort Frederick State Park) and Cunningham Falls. Both can offer some good fishing.
This time of year is tough on everyone, in a couple weeks once water gets 55-60 degrees things will get a lot better.
