Project overview

In 2021, the City of Bozeman partnered with the GCF team to remap open channels both within and beyond city limits, with early support from key stakeholders including the National Park Service. 

The most recent phase, completed in June 2025 in collaboration with the City of Bozeman Stormwater Division, marked a major milestone in the effort. To date, the project has successfully remapped over 370 kilometers (230 miles) of open channels, combining on-the-ground verification with precise digital edits informed by high-resolution imagery and LiDAR data delivering an unprecedented level of accuracy and detail.
