The Fremont River in this section has remarkably low confinement characteristics, with only 10% of the study reach classified as confined and just 5% constricted. This indicates a channel with exceptional freedom to migrate laterally across its valley bottom. The 3 km study reach has an expansive riverscape width of 800m, unconfined valley setting that allows for extensive floodplain development.

The channel occupies 90% of the valley bottom, while active floodplain comprises 95% of the valley bottom area. Only 5% is classified as inactive valley bottom. These show a highly dynamic, active system with minimal disconnected surfaces. The Fremont River appears to represent a textbook example of an unconfined, alluvial system with extensive floodplain connectivity.
