California's water resources are under immense strain as the Sierra Nevada snowpack dwindles to just 18% of its average volume, marking the second-lowest April reading ever recorded. The Department of Water Resources (DWR) reports that unprecedented March heat and high-elevation rain have triggered an early and rapid snowmelt, effectively eliminating the snowpack months ahead of schedule. Historically, the snowpack acts as a natural reservoir, accumulating water during winter and releasing it gradually in spring and summer to replenish rivers and reservoirs.
