River Flows
Live gauge readings for the South Fork Boise, pulled straight from USGS every time you open this page (nothing is cached on the site, so it’s as fresh as the gauge). Flow is in cubic feet per second; the South Fork is a tailwater below Anderson Ranch Dam, so releases, not weather, drive most of what you see.

Source: USGS National Water Information System api.waterdata.usgs.gov, 15-minute values. Provisional data, subject to revision. Water temperature shows only where the gauge has a sensor. A big jump in flow in 24 hours usually means a release change: fish may relocate and wading can get sketchy, so check before you cross.
