Safety details

- Launch only at the Idaho Power Lower Salmon Falls whitewater access and take out at the Bliss Bridge parking area before the Bliss Dam exclusion zone. Twin Falls County prohibits public access immediately below the dam, spillway, powerhouse, and upstream buoy line.
- Use 4,000 cfs as a published runnable floor, not a guarantee. Recheck the direct 13135000 gauge, dam operations, weather, water temperature, wind, and the current channel before launch.
