The Maryland Lines are the highest volume channel of great falls. These 3 drops are generally run only at low water, and there is no easy line.
Maryland Side - Paddlers may put in anywhere on the Maryland shore, but may not leave the boardwalk across Olmstead Island. To run the Falls from the Maryland side, most people put in above and run the aqueduct dam, or put in below the dam at higher levels.
Virginia Side - Paddlers may not put in upstream of the Falls. To run the Falls from the Virginia side you must put in at Fisherman's Eddy and then ferry and carry above both O-Deck rapid and the Falls themselves.

Also known as Sunburst. The line is level-dependent. Here are my general rules of thumb based on the Little Falls gage:
LF > 2.80 - Build up some speed and launch off the end of the diving board. This is quite possibly the sickest boof known to mankind. Miss the boof and learn how Pummel got its name.
2.60 < LF < 2.80 - The boof kicker turns into a rock, so run right side instead.
LF < 2.60 - The right side dries up at drought levels, forcing you to run the Notch on the left, which is one of the sweetest lines out here.
there are also other smaller chutes to the left of the notch that have been run at higher levels.
Below Pummel you have (from left to right): Pencil Sharpener, Z-Turn, and Charlie's Hole
Enter the narrow slot against the river left shore, boof 2-3' onto a boil, and slide down a broken shelf. You must anticipate the cross current or it will push you into the inhospitable crack on the left. Pencil Sharpener is the preferred option when LF < 2.80.
A 10-foot sluice into a super-powerful hole surrounded by underwater sieves. It’s named after Charlie Crowley, who escaped by crawling out along the bottom (bursting both eardrums in the process). This line used to be run regularly by boofing left into the eddy, but after numerous close calls and one fatality almost nobody runs it anymore. There is very little margin for error.
Start left of center, then cut hard left down a twisting drop next to a huge midstream rock. Be careful not to get washed around the right side of this rock into Charlie's Hole. Choose a conservative line. Z-Turn is the preferred option when LF > 2.80.
The scariest hole on the Potomac other than Charlie's, Horseshoe has been the site of many near-drownings. The line is level-dependent. Here are my general rules of thumb:
LF > 2.90 - Left line. Boof onto a rocky runout.
2.60 < LF < 2.90 - Far Right (standard) line. slide down the entrance, dont spin out, and boof off the shelf that extends past the hole. You can approach this directly or by doing a hairy ferry on the SOS wave at very low levels.
LF < 2.60 - Center line. super low water only. Boof off the knuckle through the hole.
If you get stuck in Horseshoe the odds of surfing your way out are slim, so save some energy for the swim.
