Boise River at Glenwood Bridge — Streamflow

Current Status: Discharge is 658 ft³/s, running 32% below the 5-year median. This represents a significant dry period for the Boise-Snake basin.

Recent Trend: The river has dropped sharply over the past month (down 67.6% since early June, from ~2,030 to 658 ft³/s), consistent with late-summer declining flows after spring snowmelt. Week-over-week, the river is stable (-1.9%), suggesting conditions have plateaued at current low levels.

Seasonal Context: Year-over-year comparison shows discharge is 31.6% below last year at this time, indicating this is tracking drier than the prior year. The alignment of the year-over-year and 5-year median comparisons (-31.6%) suggests this dry pattern is below normal for July.

Interpretation: The Boise River is in a dry phase typical of late summer, but deeper than historical baseline. Monitor for continued low flow conditions into late summer.
