Awesome to hear..
Eagle Creek is certainly a pool-drop run. It's pretty much a few big drops in a creek with large, slow pools in between.
I haven't ran the length of the run but I have dropped Punchbowl. They say Punchbowl is a pretty hard hit for it's 30-35 foot height. While I wasn't injured and felt no pain after, it was a significant blasting hit.
Metlako is about the easiest of all waterfalls in it's height range. So if you want to run a big one, this one might worth considering. Like all large waterfalls though, a small error could be costly.
You park at the take-out and hike up the creek. While boaters have hiked up further, most go up four miles to Skoonichuck Falls, which is like a 35 footer immediately followed by a fifteen footer. You can see most of the drops on the hike up. It's a very beautiful and popular hike so people will stare at you like you're nuts as you make your way up the canyon.
I would suggest going to Oregon Kayaking
and clicking on Creeks, then click on Eagle Creek. OregonKayaking.net is among the best websites and resources the paddling community has, in my opinion.
