Welcome tserberis and MARsSPEED!!!
MARsSpeed, does you name have anything to do with Summit Point Raceway?
I have heard a lot of good fish from Lake Linganore but I have never been able to fish it before.
The water is down at Black Hills because they pull water out once every spring and fall. I imagine the bite is slower due to weather and fish being locked on beds. That should change soon. Hoping to get out there saturday if I can find someone with an empty back seat.
Basser89 is correct, there are no pike in the Potomac. In the Washington Country stretch there is a good population of musky but not to many farther downriver. As for the snakehead, I have only heard one reported caught in the upper, around the Whites Ferry area.
