Depends on who your talking to...and EF lists the same run twice. So starting at the base of the canyon.
On the right you see a lowhead dam and after a coupleof turns you see a 15ft dam on the left...this is the Res to canyon mouth section...rarely any water.
Between the 15fter and the large dam on the left...probably 5-6 miles up is the below dam section. This is often broken into 2 runs as a park on the right lays 1/2 way in between...The 1st 1/2 goes at a lower flow than the second 1/2.
Then the below drake section starts at the pulloff across from the post office on the west side of drake and goes until the big dam/res.
The main section starts 2.5miles above drake at the large pullout on the left hand side and goes until the PO in drake.
Immediately above the main section for 3/4 mile is the Gnarr section.
So the upper section/s are above the Gnarr...but I've heard the section below drake called the upper section since the run below the big dam is sometimes called the lower section? The main section and Gnarr are always called that. Can't wait for tomorrow...
