Arizona snow pack levels have fallen 24 percent since mid-January due to lower precipitation, according to the Natural Resources Conservation Service (NRCS) in Phoenix, Ariz.
Arizona snow pack fell from 106 percent of normal on Jan. 15 to 86 percent on Feb. 1 due to lower precipitation, NRCS reports. Snowpack levels are well below normal in all basins, except the Verde River Basin, which is at about normal for this point in the season.
Precipitation in January was well below normal throughout the basins. The Salt and Verde River reservoir system stands at 87 percent of capacity while the San Carlos Reservoir is at 13 percent of capacity.
The forecast now calls for well below normal runoff in all basins for the spring runoff period.
Snow water equivalent levels are now generally well below normal, ranging from a low of 49 percent of average in the San Francisco-Upper Gila River Basin to a high of 93 percent of average in the Verde River Basin.
NRCS’ stream flow forecast calls for well below normal stream flow in all basins for the spring runoff period, ranging from 28 percent of median in the Salt River near Roosevelt to 45 percent of median in the Verde River above Horseshoe Dam.
