Overall, the average water content of California’s snowpack was 26 percent of the expected April 1 normal and continued to remain significantly below normal. The relative composition of the Sierra Nevada snowpack was 28 percent of April 1 normal for the northern Sierras, 26 percent of the April 1 normal for the central Sierras, and 33 percent of the April 1 normal for the southern Sierras.
During normal water conditions, January and Feb. are usually wet. However, the dearth of winter storms has caused state and Federal water managers to announce that projected water deliveries for the upcoming water year will be substantially below normal contract maximums. Although March affords an opportunity for chance for more precipitation, both the state and Federal water projects have announced reduced deliveries for the upcoming water year.
The reduced water deliveries are expected to result in reduced hydropower generation output for the Central Valley and State Water Projects. The impact of reduced water deliveries are, however, somewhat mitigated by last year’s above-normal precipitation which resulted in higher-than- average starting reservoir storage levels.
