Thanks Idaho Trails Association and letting me camp, work and watch the Selway River rise and fall this May. Here’s a summary about the climatic conditions (daily/weekly weather, cold & warm fronts, record high day & non-freezing night temps, snowmelt rates, lack of spring precipitation) that produced this spring’s Selway River hydrograph shape. It’s a complex world out there. Hopefully this helps explain the diurnal river changes and why our rivers flow the way they do as our winter snowpack melts in the spring.
Snow Weather and Flow 
Ron, thank you for the report! It really helps explain my confusion after what I thought was a great snowy winter turned into a weaker run off and faster than I had expected. I was mostly watching the Bruneau and in April I predicted it would run at my or above my min levels well into June. It did do that but not at levels that I am good with. That hot spell in May really did some dammage to the snow pack.
Thanks for alll the details and for dumbing it down for a guy like me. I appreciate and learned a bunch, like “Seed line”. New term to me. Thanks
