If you access the link, go to the daily statewide reservoir report.

The "water year" runs from October 1 through the following September 30, so we just started a new year. Reservoir capacity updated for October 3, 2024 (using threepointer's scale). Listed with % of Average to date, and the % change from six weeks ago:

Large (1 MM+ AF):
Oroville, 55% / 98% / (-16%) 
Shasta, 61% / 109% / (-1%)
Pine Flat, 40% / 134% / (+19%)
San Luis, 50% / 116% / (+9%)
New Melones, 76% / 137% / (+2%)
Trinity, 70% / 115% / (+3%) 
Don Pedro, 75% / 109% / (-1%)  
Lake McClure, 68% / 141% / (+10%)  
Berryessa, 85% / 117% / (+1%) 
Almanor, 70% / 109% / (-2%) 

Medium (300k - 999k AF, where available)
Folsom, 47% / 94% / (-1%) 
New Bullards, 67% / 106% / (0%)
Diamond Valley, 97% / 131% / (+5%)
Millerton Lake, 47% / 100% / (+12%)
Isabella, 29% / 102% / (-6%) 
Lake San Antonio, 74% / 156% (+2%)
Lake Tahoe/Tahoe City, 74% / 197% / (+18%) 
Nacimiento, 56% / 144% / (+2%) 
Camanche, 86% / 141% / (+7%)
New Hogan, 57% / 149% / (+7%)
Castaic, 85% / 103% / (-6%) 
Clear Lake, 28% / 115% / (0%)

SF Bay Reservoirs (and of local interest, where available)
Hetch Hetchy, 80% / 101% / (-1%)
Calaveras, 88% / 197% / (+6%)
Del Valle, 42% / 95% / (0%)
Lexington Reservoir, 55% / 148% / (+4%)
San Antonio Reservoir, 99% / 113% / (0%)
Crystal Springs Reservoir, 75% / 113% / (+2%)

Sixteen up, eight down, five unchanged. Starting the year pretty strong, I think. 

But will this be a wet or dry winter? Six weeks ago, ABC reported a weak to moderate La Nina (74% chance of development between Nov and Jan), with an overall trend for dry conditions for California.
