Is it possible to float the Portneuf River between McCammon and Inkom, and are there any public access sites along that stretch?
There is one fishing access on the Portneuf River between McCammon and Inkom. The access is called Crane Creek. Here is a link to help you locate the site:http://fishandgame.idaho.gov/ifwis/fishingplanner/access
Because of all the lack of road crossing to and all the private land, I do not believe you can float from McCammon and Inkom. IDFG has sampled short reaches of the river but have had to obtain permission from landowners to access those areas.
