A real, north-central-Montana plains climate

Fort Benton experiences cold winters consistent with Montana's broader four-season, north-central plains climate profile (base record).

Real, documented Missouri River flood history

The Missouri River at Fort Benton carries 122 years of recorded gauge data, with the 1908 flood the most significant on record at 140,000 cfs -- a real, documented hazard (base record).

The historic district sits directly along the river levee

The Fort Benton Historic District -- a verified National Historic Landmark District -- sits directly along Front Street, the levee, and the bridge on the Missouri River, meaning the town's most historically significant structures carry real, direct river-adjacency exposure (base record).

A real, disclosed gap in current flood-zone data

This pass did not independently confirm a Fort-Benton-specific FEMA flood-zone designation despite the documented flood history -- a real, disclosed gap; confirm current, address-specific data directly via the FEMA Flood Map Service Center.
