Logan River

About

Logan River, Utah — 1820s-50s Fur Trade, 1859 Logan Settlement, 1900-1912 Stokes Dam, 1990s-2010s Restoration 50-mi. At the gaging station known as Logan River Above State Dam, near Logan, the river reveals itself in numbers as much as in current, its stage measured continuously where the channel passes the dam (Source: waterdata.usgs.gov). On the morning of June 18, 2026, at eight o'clock Mountain Daylight Time, the gage read a height of 2.99 feet — a reading that sits comfortably in the lower-middle of the river's working range (Source: waterdata.usgs.gov). That range itself tells a story of restraint and extremes: the station tracks the water between an operational minimum of 1.3 feet and a maximum of 12.5 feet, the full span across which the river is monitored throughout the seasons (Source: waterdata.usgs.gov). Beyond mere observation, those measurements carry public consequence, for the gage anchors a tiered flood-warning system that begins with an action stage at 5.2 feet and climbs through minor flooding at 5.5 feet to moderate and major flooding at 6 feet (Source: waterdata.usgs.gov). Today the Logan River remains a closely watched waterway, its steady stage readings guarding the valley below against the threshold where ordinary flow becomes hazard (Source: waterdata.usgs.gov).
