Marin's reservoirs jumped 10% in one day (scroll to the bottom of marinwater.org/sites/default…)

IIRC Marin's reservoirs fill fast (large watershed area / reservoir volume) and drain fast (small reservoir volume / demand).

The watershed area is also fairly small (you and I have hiked from Lake Lagunitas to nearly the top of Mt Tam) so the storm will end up in the reservoirs almost immediately and no over several days.

Still, the total capacity of Marin's 7 reservoirs is 1/44 that of Lake Oroville or 1/57 of Lake Shasta. Being in a rainier area does help.
