This is an amazing view if you have the skill to get up here - the second largest waterfall by flow in the United States, I think.  Launch from Clackamette Park or closer.   Watch out for lots of fishermen, their lines, and sea lions

• Water Level (note that this area is tidal):  http://water.weather.gov/ahps2/hydrograph.php?wfo=pqr&gage=orco3
• Water Flow Rate:  http://levels.wkcc.org/?D=wr1#Awr1
• Paddling up on river left is calmest, river right has back eddies you can use.  Deep, except for some obvious rocks that are exposed at certain tides/flow levels.
• You are not allowed to get closer to the falls than the line between the top building on either shore
• Intermediate/advanced will have a lot of fun from 30-40,000 cfs.  Standing wave on river right at 35-40,000 cfs on slack to first 30 minutes of the ebb.
• Stay away past 40,000 cfs.

Notes from the two times I have been there:

• 20,000 cfs:  Areas of strong current, boils, currents from multiple directions
• 14,200 cfs:  Outfall from falls quite manageable, outflow from dam quite fast but manageable with skill
