Access caveats and watch for
Access caveats
- Long Bottom is a real public access, but KDFWR says the final road approach is extremely rugged and best suited to high-clearance four-wheel-drive vehicles.
- Thunderstruck is the intended finish. KDFWR warns it is easy to miss once you drop through Thunderstruck Shoals unless you are watching the left bank closely.
- Same-day USGS flow on this run was above the official preferred band, so expect a stronger-water feel than a lower-band casual outing.
Watch for
- Long Branch shoals, Thunderstruck Shoals, and fresh wood after rain.
- Muddy footing and rough access logistics at Long Bottom.
- Private banks and the temptation to drift past Thunderstruck instead of finishing at the named public ramp.
