Reservoirs in Good Shape Despite Low Rainfall

Posted on March 20, 2015 at 8:27 AM by Ann Vallee

Thanks primarily to heavy storms in December, and again in early February, MMWD's reservoirs contain slightly above-average storage levels today. But customers' ongoing conservation efforts have also made a difference. Our running 12-month production figures show a reduction of 15% since mid-March 2014. As we head into the warm summer months, conservation will be even more critical to the preservation of our existing supply.

Here are the current water statistics:

Reservoir Levels: As of March 15, reservoir storage is 76,820 acre-feet,* or 97% of capacity. The average for this date is 72,119 acre-feet, or 91% of capacity.    

Rainfall: Rainfall this year to date (July 1, 2014 - March 15, 2015) is 36.88 inches. Average for the same period is 43.07 inches; last year on this date we had 26.91 inches.

Water Use: Water use for the week of March 9-15 averaged 19.69 million gallons per day, up from 15.41 million gallons per day for the same week last year.

Creek Releases: During the month of February 2015 MMWD released 433 million gallons, or 1,328 acre-feet, into Lagunitas and Walker creeks in west Marin for habitat enhancement.  

Water use and reservoir figures are updated weekly and can be found on our Water Watch page.

*One acre-foot is 325,851 gallons
