lees ferry research
I've been wanting to get down there and fish, and have done some research. The access is by motor powered boat, or down one trail which is not marked and may require rope. If you were brininging down rubber, it certainly would require rope. There is a group out of page that does scenic tours that will pull you up to the dam for a fee at the end of each day. They have a charge per person and per boat. . The water is flat, and slow. The CFS is big, and tey are trying to keep it very steady in recent years withthe exception of well forcasted dumps to try to release sediment. Fishing is off of sand bars with nymphs and sight casting of micro midges. There is camping first come first serve at some sites. you can hike up to the first few sand bars, but the feedback is that the best bars are taken by guides early in the morning, driving upstream with headlights at peak spawns.
hope this helps.
