Reservoirs Above Average as Summer Approaches

Posted to MMWD Blog: Think Blue Marin on May 25, 2016 at 11:31 AM by Ann Vallee

Thanks to customer conservation efforts and near-normal rainfall for the 2015-16 winter, MMWD's reservoir levels are well above average for this time of year. Average storage for this date is 88%; actual storage is 97%.

Here are the latest water statistics:

Reservoir Levels: As of May 24, reservoir storage is 77,026 acre-feet,* or 97% of capacity. The average for this date is 70,292 acre-feet, or 88% of capacity.

Rainfall: Rainfall this year to date (July 1, 2015 - May 24, 2016) is 49.70 inches. Average for the same period is 51.20 inches; last year on this date we had 39.64 inches.

Water Use: Water use for the week ending May 24 averaged 23.77 million gallons per day, compared to last year when water use for the week was 21.53 million gallons per day.

Creek Releases:
During the month of April 2016 MMWD released 389 million gallons, or 1,194 acre-feet, into Lagunitas and Walker creeks in west Marin for habitat enhancement.

FAQ: Can MMWD Build Bigger Reservoirs?

Posted to MMWD Blog: Think Blue Marin on March 25, 2016 at 4:26 PM by Ann Vallee

Especially  in  a  rainy  year  like  this  one,  customers  ask  if  we  can  enlarge  our  reservoirs to hold more water by raising the dams. While creating additional storage may seem like good insurance against drought, it is not as simple as it sounds.

MMWD’s rights to divert and store water are granted by the State of California. The state has authority over how much water we can legally take from our local creeks to store in our reservoirs. As part of our agreement with the state, MMWD is required to maintain a certain amount of water in the creeks for fish habitat. This means  we  actually  release  water  every  year  from  our  reservoirs  into  the  creeks,  but  with  good  reason.  Endangered  coho  salmon  and  other  species  living  in  the  creeks need an adequate flow of water to ensure their health and survival. In 1980, when the district last requested state permission to expand storage, the result was 15 years of studies and hearings prior to reaching a court-ordered agreement that required  us  to  release  more water  annually.  In  summary,  since  the  state  will  not  allow MMWD to divert and store more water, increasing the size of our reservoirs would not provide any benefit.

The  simplest  and  least  expensive  way  we  can  maximize  our  water  supply  is  through conservation, not by creating new or bigger reservoirs. That’s why we ask our customers to use water wisely and why we offer a variety of conservation programs and rebates to help. Thank you for doing your part!

Reservoirs Above Average in Spite of Dry Spell

Posted to MMWD Blog: Think Blue Marin on February 24, 2016 at 10:02 AM by Ann Vallee

Thanks to heavy rains in December and January, MMWD's reservoirs are still above average in spite of the warm, dry conditions in the first half of February. Additional rain is still welcome, however. The reservoirs have some capacity remaining and local waterways will benefit from any rainstorms that come our way in the next few months.  

Here are the latest water statistics:

Reservoir Levels: As of February 23, reservoir storage is 78,719 acre-feet,* or 99% of capacity. The average for this date is 69,611 acre-feet, or 87% of capacity.   

Rainfall: Rainfall this year to date (July 1, 2015 - February 23, 2016) is 33.30 inches. Average for the same period is 37.57 inches; last year on this date we had 36.86 inches.

Water Use: Water use for the week ending February 23 averaged 14.68 million gallons per day, lower than last year when water use for the week was 16.19 million gallons per day.

Creek Releases: During the month of January 2016 MMWD released 176 million gallons, or 541 acre-feet, into Lagunitas and Walker creeks in west Marin for habitat enhancement.
