A set of wave/holes ("Center Wave", "Spin Hole", "Half-way Wave", and "Dream Hole") form under the 1st Street bridge, depending upon the water level:
3,500 - 10,000: Playable, but tame. (Pretty much just flatspins and surfs.) Many may consider this 'too low'.
10,000-15,000: Two waves are well-formed. Generally still too shallow for vertical moves, but still decent play.
15,000 - 20,000: Great surfs and spins in the big wave. Retendos are possible, but generally still a bit shallow for full vertical moves. "Halfway Wave" appears, steep, narrow and green.
20,000 - 30,000: Dream Hole begins to form, but may be irregular and changing moment to moment.
30,000+: Well, what can we say . . . DREAMLAND! Imagine, a cartwheeling hole 100' wide and friendly as could be!
