i would say they are not runnable at current flows. there's also a big diversion on the encampment just upstream of the confluence with the platte. it's pretty clean, and i've run it a few times but not at current flows. i would guess it has to have a nice hole at the bottom.
the suspension bridge just upstream of treasure has to be impassable at current flows too. i've had to duck under that thing at 2k before.
if you're looking for the drakes, i'd guess they're a couple of weeks away. water temps have to still be too cold.
By the waterside I will lay my head.
Listen to the river sing sweet songs to rock my soul.
