DD Wave (Dam Drop)

Just downstream from the Pedestrian Bridge, this wave is green most of the time, but can also become foamy at low levels.

0-600

ELF flows. This feature can either be green or foamy.

Playboat: Very minor front surfing.

Board: Go for inflatable or a foamie you don’t care too much about as its pretty shallow.

600-1000

Usually green but sometimes foams up.

Playboat: Front surfs and flatspins

Board: Still shallow (still recommend inflatable or foamie).

1000-1500

The wave is green, has flat spots guarding the little bit steeper middle area.

Playboat: front surfing and maybe flatspins on the lower end of this range.

Longboat: at the higher end of this range the wave becomes too flat for playboats so bring your longer boat and soul surf! (I have seen a sea kayak surf but they tend to purl a lot.)

Board: it is possible to surf with a fast, floaty board. Boards with high volume, sleek, and around 6' seem to work best. SUPs and work too. It can be challenging to get to the steeper center area but it is possible. Carves and shuvits possible.

1500-3400cfs

Playboat: its too flat and fast to surf a playboat. The pocket on river left is weak, may be able to briefly surf it.

Longboat: Able to surf in a long boat.

Board: a bit of an awkward level, the wave becomes tricky to catch and easy to flush off of -- you gotta move and generate speed. Fast boards tend to have more success. The upper end of this range is better

3500-5500

The main portion continues to be green. Eddy access is easier from river left via the pocket.

Playboat: the face of the wave is too flat and too fast for short boats to surf. Stick to the river left pocket for a little front surfing action.

Longboat: you can still surf a long boat if you want, but most head down to the other features for playboating.

Board: SUPs and shortboards can be surfed in the river left pocket at starting at around 3500cfs. The sweet spot appears to be 4000-5000 cfs for short boards.

5500-10000

Eddy access to the main wave becomes blocked by a guard curler. The wave is green and nearly uncatchable on the fly in boat. Boards may be able to catch the wave, but its fickle and tough to stay on. At the high end of this range (7500-10000) there is a secondary wave that forms behind DD Wave which tends to change moment to moment but does have eddy access and is entertaining to try to surf/spin in a boat. Good for practicing how to wipeout in style!

At about 12000-13800 the top wave can be caught on the fly in a boat or on a sup for front surfs and spins -- fun to be surfing on that much water through the park. A portion of the wave on surfers left builds (green) and crashes just a few feet from you! The secondary wave is also catchable so after you flush off the top wave, take a few strokes and you’re ready for another ride. The secondary wave is a bit foamier but very waveish, front surf and spins mostly.

Above 13,800 cfs all features become flat/washed out.
