Between Memorial Day and Labor Day, there is no powered boats allowed north of Willow on Sundays and Mondays.
You can thank you local kayaking tree hugger for that one

So consider that river of the closed until the end of may.
I dont mind sharing that strech of river (we've got 5 days, they get two

) but on saturdays "SLOWER TRAFFIC KEEP RIGHT" -they're usually streched all the way across the river like a floating road block, its like riding a 10 speed bike on the 405

Where at at mead? temple? lv marina?
FYI: willow has a 'fee station' under construction, prolly ready by may (I always get the lake mead pass in december/january for katherines)
