If you go down to the launch and take those directions you will understand.
Thedirections for low water are right on the mark!!
the STUMP in aprox 6 feet in diameter...coweeman is accross the river from launch and 1/8 mile down river just above the bridge.
I talked to a guy last week that says you go like hell into the hole at the launch to get over the bar

then FULL REVERSE so you don't stack up on the rocks at the launch...
better off using rainier or willow grove and burning the extra gas if your skitish on this low water ramp
Go over the Cowlitz bridge at LOW TIDE..look at the river.
You will understand completely
