Roseville gets full CVP allocation; snowpack low but local precipitation and ASR recharge bolster supply
Summary
Water Utility Manager George Hansen told the commission Roseville received a 100% CVP contract allocation for 2026; northern Sierra precipitation tracks near average but snowpack is unusually low; the city recharged about 4,500 acre‑feet into its ASR wells since December.
George Hansen, Water Utility Manager, presented the 2026 water‑year update to the commission, reporting that the Bureau of Reclamation allocated 100% of Roseville’s Central Valley Project contract supply for the year.
“We received a hundred percent allocation of our contract supply,” Hansen said, calling that good news for the current water year. He said northern Sierra precipitation is tracking near average (about 98% of the long‑term average) and that local precipitation for the early months of the water year is roughly 110% of the median.
Hansen cautioned that snowpack remains very low: the presentation showed April 1 snow‑water equivalents at only a few percent of historical averages in many Sierra basins (Northern Sierra ~2% of April 1 average; statewide ~4% of April 1 average), indicating that most runoff for the year has already occurred and reservoir storage now drives supply outlooks.
Hansen also highlighted Roseville’s Aquifer Storage and Recovery (ASR) program: because of surplus surface water earlier in the season, staff recharged about 4,500 acre‑feet across six ASR well sites beginning in mid‑December to build backup supply for potential dry years.
“That helps us build the backup storage,” Hansen said, noting ASR is a tool to increase resiliency in future dry periods. Commissioners asked about predictability for next year; Hansen said hydrology is variable and the city will monitor conditions in the fall and update planning accordingly.
The commission received the report for information; staff said they will continue to track conditions and update both the commission and the City Council as needed.
