By the middle of July last summer Star Valley was very dry with virtually no rain having fallen since May. However there has been a major improvement in the Valley water conditions heading into the coming winter. Last winters snowpack was below normal and with the ground water depleted by the previously very dry summer, much of the snow melt went to recharge the ground water, leading to the current very low levels in reservoir systems of the area.
However beginning the last of July 2021 much of the area has received beneficial precipitation. Most recently was this past week when up to 2 inches or more was measured over much of the area west of the Salt Range including Star Valley. These last nearly 3 months have provided a significant recharge of the ground water, which will favor a much improved runoff next Spring provided the winter snows are substantial
As a comparison, the 3 month period ending October 10th this year at Star Valley Ranch of 8.37 inches is almost 8 times greater than the same period last year of 1.15 inches. Smoot at the south end of the valley has had 6.24 this year vs 1.27 last year.
A couple of charts covering the last 3 months clearly illustrate the widespread nature of precipitation since mid July

All of Lincoln County has benefited from the rains of the past 3 months.
