Idaho River Flow Rates & Stream Gauge Data
Live USGS stream gauge data for Idaho — current CFS flow rates, gauge heights, water temperatures, and wading conditions for Idaho rivers and streams. Updated every 15 minutes. Know before you go.
Planning with Idaho river conditions
Browse USGS monitoring stations across Idaho rivers and streams. Each gauge page shows current readings plus 7, 14, and 30-day flow-rate charts with condition indicators. Compare the station name and location with your intended reach, then use the recent trend alongside the current reading. Rain, snowmelt, dams, tributaries, and the distance between stations can produce different conditions on the same river.
Idaho river guides
- Henrys Fork — Henrys Fork is a famous Idaho trout river with spring-fed and tailwater influences. The river's multiple gauges make reach-specific flow checks much more useful than a single basin-wide estimate.
- Silver Creek — Idaho's Silver Creek is a spring creek destination where clear water, aquatic vegetation, and exact presentation make current conditions and hatch timing especially valuable.
- Rock Creek — Idaho's Rock Creek has extensive mapped trout-water coverage and a gauge at Twin Falls that helps anglers put recent precipitation and runoff in context.
