You can run Walnut quite a bit above 2000 CFS, you must be aware that around this level, The Tubes (Marajuannica Falls) becomes extremely sketchy. Local paddl
About .25 miles after going under the first railroad bridge, you will come to a two tubes that the river flows into. They were put there by the railroad company. You must take the left tunnel to avoid being turned into fish bait! In low water, this falls is easy because there is not much of a hole at the end of the tunnels but still sounds like Niagara Falls while in the tunnel! In high water (above 1.5 feet), you should probably portage as a river wide hole forms which can easily suck boats back into it and surf you over to the right side and into the sharp metal and you could die! After comming out of the tunnels, look on the right side of the river and you can see where this rapid gets it's name. There is graffiti of a flag of a marijuana leaf on the tunnel structure and it says Marijuanica.
