Muddy Creek has high levels of confinement, with 90% of the study reach classified as confined and 85% constricted. This channel is largely bounded by valley walls with limited opportunity for lateral migration. The 3 km study reach has a relatively narrow riverscape width of 20m, suggesting a constrained corridor typical of many intermountain western streams.

The channel occupies 75% of the valley bottom, while active floodplain comprises 80% of the valley bottom area. The remaining 20% is classified as inactive valley bottom, potentially representing terraces or other disconnected surfaces. These metrics suggest a predominantly active system but with some areas that have become disconnected from regular floodplain processes.
