I have boated both above the 10 freeway and below the 10 freeway. I personally like Lost Lake for the North side of the Dam and McIntyre for the South side of the Dam. The problem is finding a place to stay. I stayed in a 5th wheel at Lost Lake and a mobile home at McIntyre and it was bitchen. If you call the local stores you may be able to get a hold of someone that will rent you a trailer or mobile. I have also stayed at the local flea bag hotels (they are ok if you're spending most of your time on the water). Also, staying in parker at the Blue Water Casino isn't that bad either, it's only a 30 minute drive to Lost Lake if you take Angnes Wilson Rd to cross the river from AZ to CA. I haven't been out that way for a while so others may have some other ideas for you.
Lost Lake is cool because they have the Saturday Night Drags (at least they use to).
They would also have a band on the big weekends. They have fuel at Lost Lake but you might want to call to make sure they have 91 Octane if that is what you run.
One of the launch ramps is in a cove and is protected so you don't have to launch into moving water.
Just down river there is a nice sandy beach.
There is also a nice cove just past the three bends in the river that everyone hangs out at (if the waters low you will have to walk your boat in).
There is also some nice beaches up river.
My best trip has been a day trip from McIntyre to Fishers. It's about a 65 / 70 mile trip each way though. I have always wanted to do a week trip from McIntyre to Fishers. Stay at McIntyre for a couple days then camp for 2 days and then stay in Fishers for 2 days then head back up to McIntyre. There are several boat-in only camping sites on the way to Fishers from McIntyre. We went on a week day which was a Monday since they only have gas at Walters Camp Thursday through Monday.
McIntyre also has a launch ramp which is also in a cove so you don't have to worry about the current. They also have fuel.
