Potomac

The Potomac River is the river that runs its course through the Capital Wasteland. Before that, the Potomac runs along most of the border of Maryland, West Virginia and Virginia and after the cutting through D.C., continues along the border of Virginia until it reaches the Chesapeake Bay.

Layout
Starting in Maryland and West Virginia with the North Branch Potomac River and South Branch Potomac rivers meet, the Potomac courses along the borders of both states until it reaches the Washington D.C.

Capital Wasteland
Its course is generally northwest to southeast and essentially divides the Wasteland in half. Many portions of the river have dried up all the way to the river bed. To the north and east of the river is Maryland, to the south and west is Virginia, and all of Washington, D.C. is on the east side. It empties into the Tidal Basin along with the Anacostia River. Its waters are moderately radioactive, making swimming a somewhat hazardous method of crossing depending on the width of the section attempted. It is best to find an intact bridge or narrow or dried up section. Swimming down the river allows the player character to reach late game areas relatively safely. It is possible to bypass a number of main quests by swimming the river to the Jefferson Memorial.

There are a few boats in the river both above the surface and resting on the bed of the river, these boats sometimes contain ammunition and first aid boxes. Mirelurks are often found in and around it, with mirelurk hunters and mirelurk kings found at higher levels. The murky waters of the river make noticing mirelurks difficult in certain cases, as they can blend into the surrounding rock formations.

In the Broken Steel add-on, the Tidal Basin in front of the Jefferson Memorial is pure and drinkable thanks to the activation of Project Purity. The Potomac River remains irradiated, as the Basin has been dammed off and the purifier was never intended to affect the river itself.

Appalachia
The Potomac River appears only in a small, unmarked portion at Harpers Ferry in the Mire.

Appearances
The Potomac River appears in Fallout 3 and Fallout 76.

Bugs
The Tidal Basin may remain irradiated in Broken Steel, as the script may not fire correctly.
