Sedanka Creek floats use Yurt like tent cabins that are set up at the beginning of each season,  they include electricity, hot showers and toilets! There is a dining cabin as well.  This is practically a lodge even though it is refered to as a float trip.

The Zhupanova float trips actually have permanent cabins built at different points on the rivers. they include electricity, hot showers and toilets! There is a dining cabin as well.  This is practically a lodge even though it is refered to as a float trip.

Other Semi permanent tent camps use traditional Weatherport tents with wood floors. 

The mobile tent camps use lighter weight tents but still have sheltered dining areas separate from the sleeping tents.  You will have a camp team that will take down and set up camp in advance of your arriving so there is unlimited time to fish.  You give up the showers and the flush toilets though .Breakfast and dinner are served in camp while lunch is served on the river if we can tear you away from the fishing.  No float planes passing by, no jet boats, no phone, no radio, you are out in a remarkable wilderness few westerners have ever seen.
