Depending where you would like to fish.Here`s a list:Burk Lake,Lake Jackson and Occuaquan park all located on 123 towards Woodbridge in Lorton.You can launch by Ragan National into the Patomac Their should be a couple places to launch near or in Old Town Alex.

                 If you get the chance and want to drive alittle go to the Rappahanic River in Fredricksburg theres a city dock at the end of Old town great fishing clean water.

Old gaurd angler,
                           Turn on 123 from US-1 and its a about 2 miles or so on the left. Basically it`s the other side of Occuaquan. It` s worth it.If I remember right it`s bigger than Burk lake.It`` might`` be no gas engines,not sure..
                           If your stationed at Belvior, get a map there`s plenty of lakes close to you.One place to check out is a bit of a drive:Lake Orange in Orange co.down south;take 95 to rt3 Fredricksburg exit towards Culpepper about 15 miles take left on Rt.15 and go about 20+ you`ll see a sign to take a left and that takes you right there.Deffinately no gas eng.They stock it ,it cost to fish there but worth it.It`s privatly owned.Lots of crappie bass ect...My daughter at 2 was trying to hit ducks with a little pole I haveand caught a citation bass using a bobber and a minow.Bait and everything else you can buy there.
                          I`m also ex Army,86-90.
