Remember this time last year, when water stores depleted by several years of drought left water managers and consumers alike hoping desperately for a wet winter ahead? Well, Sonoma Water says the region’s main reservoirs — Lakes Sonoma and Mendocino — ended this August with the highest combined storage level since 1985, the first full year the newly constructed Lake Sonoma was filled. This, less than nine months after the reservoir on Dry Creek reached its lowest level in history on Dec. 9 — 96,310 acre feet, just more than a third full. Lake Sonoma now has nearly 240,000 acre feet in it, while Lake Mendocino, which is smaller, has nearly 84,000 acre feet, for a combined total of more than 322,000 acre feet. (An acre foot of water equals 325,851 gallons, or about the amount of water needed to flood most of a football field one foot deep.)
