Folsom Lake Storage

Current Status: 819,008 acre-feet (af) — 6% above the 5-year median

Recent Trends:

• Weekly: Down 5.2% from 863,627 af (typical seasonal drawdown)
• Monthly: Down 13.8% from 950,518 af (continued drawdown into summer)
• Annual: Up 5.6% from 775,411 af year-ago (stronger recharge cycle)

Summary: Folsom Lake is tracking well above its 5-year average for early July, suggesting healthy recharge from spring snowmelt and adequate storage heading into peak summer demand. The month-over-month decline of 13.8% reflects normal summer irrigation and hydroelectric operations, not a stress signal. Year-over-year gain of 5.6% indicates 2026 is performing better than 2025 at this point in the cycle.

Context: Storage is in a comfortable band relative to historical norms — no immediate concerns, but continued monitoring through peak summer (July–September) is warranted as demand peaks.
