Looking at the forecast and the temps last night, I'm worried that the spigot will be turned off. Last night the low in Delta was around 40, so the higher elevations were probably pretty close to freezing. Tonight the low in Delta is forecasted to be 31, so the higher elevations will for sure be shutting the flow down. The Saturday night low will be 40 in Delta as well.
For perspective, last weekend the low while we were camping at the take-out was around 50, and we had medium-low flows. It took til Sunday for the FU rocks to be covered on the upper section.
Not trying to be a downer, but I'm not encouraged. I hope I'm wrong, and the run is still pretty entertaining at low water.
