Fishing for carp with flies or other methods

Hey all - I did a donation kayak fishing trip for the Native Fish Society and the winning bidder wants to fly fish for carp sometime in June. This is something I have also wanted to do but I don't know many locations around Portland and it would be great for the person to at least see a couple carp. If anyone is willing to provide some recommendations I would appreciate it. We will be using Hobies so the water cannot be super shallow. You can PM if you prefer. Again, I appreciate any suggestions.

The lakes on Sauvie are pretty solid bets.  Shallow, though.  But worth looking into.  Read up on the lakes on this guy's blog:

I've seen a ton of them at Smith and Bybee Lakes (near the confluence of the Willamette and Columbia) but never got them to bite (using bait). I saw a guy in a canoe there bow-fishing for them.

A few years ago when I lived in Yorba Linda, CA......on a 15 acre lake, hot dogs were favored by both Bass and believe it or not, Carp......some Carp went over 25 pounds......the largest bass was 14 pounds.
This was a barbless hook, catch and release lake (East Lake).....
The Bass and Catfish also loved the ducklings......they would disappear from the surface as these larger fish would feed on them

Thanks for the tips and links. I'll do some scouting on the island and post some reports.

Carp on the fly is a blast.  They are some really strong fish.

Went to Sauvie's and found some carp at Round Lake but the water had the visibility of a fresh puddle. Not certain if I want to put my kayaks in that. Looking at the gorge for the trip. Hope to post a successful video. Thanks again for the tips and if anyone has others, I would appreciate it.
