It was the question in the upper left-hand corner of the saveourh2o.org website that caught my attention. I wondered if the average person tosses away the question of conserving water like a worn-out pair of shoes. For me, the question took me back to a conversation I overheard a few weeks ago between Jack and our 80-plus-year-old neighbor.

ranch waterThey spoke of water rights, which drew me in as I hoped to glean more knowledge about a subject I knew little about. During the conversation, I learned that our ranches had first rights to our allotments, but others downstream were only given second rights to the use of that water. It was easy to understand the concern of those who might need more water than they were allowed—especially where one’s livelihood hinges on having enough water for cattle and crops. The conversation had me running to the computer to find out how these rights were established, and I found, as a side note, that the ‘49er gold rush played a huge part in the water laws of California!

While exploring the subject, I considered what water rights meant to me growing up in San Rafael. Awareness seemed to be the missing link between the two worlds. We grew up believing we had the right to turn on the water without thought of how that use would affect our neighbor. We had no restrictions regarding the time of day or year we could use water. The only minor concern was how that usage would show up on the water bill, and as a child, that thought barely crossed my mind—let alone the idea that this was a resource we needed to share with others!

Our awareness of water changed when the 1976-77 drought came. Everyone scrambled to conserve as reservoirs became dangerously low. MMWD customers cut back their consumption by 63 percent. Heritage landscapes were sacrificed to stretch our water supply for indoor use. Creative ideas about how to save water were shared in local newspapers and seen on television ads. The talk carried over to social events, educational institutions and the dinner table. Lack of rain sharpened our awareness. Many of us who lived in Marin during those days continue those water-saving habits today.

Though retired, I continue to read about water. There is a real concern about the lack of usable water for our world’s growing population. Many places suffer from horrible drought. Even in Marin—where we’re fortunate to have access to clean, local water—our supply is limited. We depend on rainfall captured in our local reservoirs. Still, most of us take for granted that when we turn on the faucet the water will be there. I wonder what we all need to do to raise our awareness to a higher level? What can you do to improve the conservation practices in your home? Are your toilets the most efficient? Is the garden mulched? Are you using smart controllers programmed to replace only the amount of water lost through evapotranspiration? Can those actions take care of our neighbors who may not have enough water?

Check out the saveourh2o.org website. There are many conservation ideas and resources for both the homeowner and the professional. You’ll find short videos demonstrating various methods of improving irrigation systems, as well as links to manufacturers’ manuals, suggested literature, tips and more. Let me know what you learned, or share your conservation ideas with other readers. Let’s all sharpen our awareness!

The dry period that started with the beginning of the year has continued right through the month of March. Average rainfall for March is 7.39 inches; March 2013 rainfall to date is 0.82 inches. The record low of zero inches of rain for March occurred in 1923.

Our reservoir storage levels are still above average, although the gap is narrowing compared to what it was earlier in the season.

Here are the current water statistics:

Reservoir Levels: As of March 24 reservoir storage is 74,869 acre-feet,* or 94 percent of capacity. The average for this date is 72,917 acre-feet, or 92 percent of capacity. Total capacity is 79,566 acre-feet.

Rainfall: Rainfall this year (July 1, 2012 to March 24, 2013) is 36.20 inches. Last year for the same period we had 33.26 inches; average is 45.23 inches.

Water Use: Water use for the week ending March 24 averaged 20.6 million gallons per day, compared to 16.4 million gallons per day for the same week last year.

Supply Source: Last week we averaged 14.8 million gallons per day from our reservoirs and 5.8 million gallons per day from the Russian River.

Creek Releases: During the month of February 2013 MMWD released 537 million gallons, or a total of 1,648 acre-feet, into Lagunitas and Walker creeks in west Marin. We release water throughout the year to maintain adequate flows for the fishery per our agreements with the State of California.

World Water Day logoToday is World Water Day. First declared in 1993, World Water Day has been observed every March 22 for the past 20 years. Recognizing that the fulfillment of basic human needs, our environment, socio-economic development and poverty reduction are heavily dependent on water, the United Nations declared 2013 as the International Year of Water Cooperation. The objective is to raise awareness of the potential for, and value of, increased cooperation in relation to water.

In many parts of the world, there is no indoor plumbing and people must travel long distances each day to get water. This chore falls mainly on women and girls who walk an average of 3.7 miles a day, carrying loads of 40 pounds in order to obtain water for their families. This job can take as long as six hours per day even though an average person in sub-Saharan Africa uses only about four gallons of water per day. Unfortunately, the daily chore of finding and transporting water often takes the place of education or other opportunities.

In the United States and other developed countries, technology has made using water very easy. We turn on the tap and clean water pours out, seemingly in an endless supply. A complex system of pipes, storage tanks, treatment plants and pumps is used to treat and deliver water to our homes, businesses, parks and institutions every day. In large part these systems are invisible to many of us. We don’t need to think about where our water comes from or where it goes after we use it. We just count on it being there when we need it.

This ease of use has resulted in a drastic increase in the amount of water we use today as compared to 100 years ago. Back in the “old days” many people had to pump and haul their own water for washing, cooking, bathing and other needs, creating a built-in incentive towards strict conservation. These days, the use of water is made even easier with appliances taking over chores like laundry and dishwashing. The Environmental Protection Agency estimates that on average a person in the United States today consumes about 100 gallons of water per day. The good news is that progress has been made over the past 40 years in stretching our water supplies through water conservation efforts and the introduction of new technologies like high-efficiency toilets, low-flow showerheads, and front-loading clothes washers.

Here in Marin, we are fortunate to enjoy a reliable supply of high quality water and a strong conservation ethic. Please show your support for World Water Day by taking action to conserve water, both today and beyond. Visit the official World Water Day website for additional information about the importance of freshwater and the need for sustainable management of freshwater resources.

Yes, that’s right. We expect to set a low rainfall record this year for the January-February time frame even though our reservoir storage levels are above average. With only 2.07 inches of rain received at Lake Lagunitas since the first of the year, and no rain in the forecast for the remaining days of February, we are on track to set a new record low for January-February rainfall. The previous low of 3.43 inches dates back to 1920. Average rainfall for January and February combined is about 20 inches.

Paradoxically, our reservoir storage levels are actually above average at 97 percent of capacity today compared to the average of 88 percent. Why? Two reasons: one, we entered the rainy season last fall with above-average storage and two, we had an extremely rainy November and December. We received 29.27 inches in the last two months of 2012, nearly double the average of 15 inches for that two-month period.

Here are the current water statistics:

  • Reservoir Levels – As of February 25 reservoir storage is 77,196 acre-feet,* or 97 percent of capacity. The average for this date is 70,074 acre-feet, or 88 percent of capacity. Total capacity is 79,566 acre-feet.
  • Rainfall – Rainfall this year (July 1, 2012 to February 25, 2013) is 35.38 inches. Last year for the same period we had 18.45 inches; average is 38.45 inches.
  • Water Use – Water use for the week ending February 25 averaged 17.4 million gallons per day, compared to 17.1 million gallons per day for the same week last year.
  • Creek Releases – During the month of January 2013 MMWD released 376 million gallons, or a total of 1,155 acre-feet, into Lagunitas and Walker creeks in west Marin. We release water throughout the year to maintain adequate flows for the fishery per our agreement with the State of California.

Reservoir levels are still well above average at 99.4 percent of capacity in spite of an extremely dry January. We received just 1.26 inches of rain this month, well below the January average of 10.93 inches. The last time we had a dry January was in 2008, when we received just 1.08 inches. This month’s rainfall is a stark contrast to the first half of the 2012/13 rainy season. By December 31, 2012, we had received 33.31 inches, compared to the yearly average of 19.64 for the same date.

Here are the current water statistics:

Reservoir Levels: As of January 27, reservoir storage is 79,082 acre-feet.* The average for this date is 64,842 acre-feet, or 81.5 percent of capacity. Total capacity is 79,566 acre-feet.

Rainfall: Rainfall this year (July 1, 2012, to January 27, 2012) is 34.57 inches. Last year for the same period we had 16.93 inches; average is 28.85 inches.

Water Use: Water use for the week ending January 27 averaged 16.6 million gallons per day, exactly the same as water use for the same week last year.

Supply Source: Last week we averaged 11.6 million gallons per day from our reservoirs and 5.0 million gallons per day from the Russian River.

Creek Releases: During the month of December 2012, MMWD released 142 million gallons, or a total of 434 acre-feet, into Lagunitas and Walker creeks in west Marin. We release water throughout the year to maintain adequate flows for the fishery per our agreement with the State of California.

This year’s early, heavy rains have produced substantial runoff, bringing MMWD reservoirs to 100 percent of capacity. Water is now flowing over the spillway at Kent Lake, the district’s largest reservoir and the last to fill. In the past 20 years, the reservoirs have filled to capacity in December three other times: 2010, 2005 and 1996. More typically, the reservoirs reach their highest levels in late March. Here are the current water statistics:

Reservoir  Storage

Reservoir storage as of December 28

Reservoir Levels: As of December 28, reservoir storage is 100 percent of capacity, or 79,566 acre-feet.* The average for this date is 72 percent, or 57,377 acre-feet.

Water Use: Water use for the week ending December 23 averaged 16.0 million gallons per day, somewhat lower than last year’s average of 18.4 million gallons per day. Last December was unusually dry.

Supply Source: Last week we averaged 10.6 million gallons per day from our reservoirs and 5.4 million gallons per day from the Russian River.

Creek Releases: During the month of November 2012, MMWD released more than 300 million gallons, or a total of nearly 1,000 acre-feet, into Lagunitas and Walker creeks in west Marin. We release water throughout the year to maintain adequate flows for the fishery per our agreement with the State of California.

emergency water supplyOne of the easiest yet most essential steps you can take to prepare for an earthquake or other disaster is to set aside an emergency water supply. Every household should keep at least a 72-hour (three-day) emergency supply of water handy. Store one gallon per person per day, or a total of three gallons per person, for a 72-hour period. Store extra water for pets and family members with special needs.

Tap water from MMWD can be safely stored in well-sanitized, food-grade containers such as plastic soda bottles. Avoid used milk jugs and containers that will decompose or break. Seal tightly, then label and store in an easily accessible, dark, cool, dry area away from solvents and chemicals. Replace every six months. Don’t forget your other emergency supplies (find a list at ready.gov).

See our emergency preparedness brochure for additional steps you can take to be water-ready in an emergency.

This fall MMWD is beginning the environmental review process for the district’s Draft Wildfire Protection and Habitat Improvement Plan (WPHIP). Formerly known as the 2012 Draft Vegetation Management Plan, MMWD has renamed the plan with the launch of the environmental review process to avoid confusion with the district’s 1995 Vegetation Management Plan. The new name also more accurately reflects the plan’s purpose. This new plan addresses fire hazard reduction and biodiversity protection on the 22,000 acres of watershed land managed by MMWD with drinking water protection as the number one priority.

The main goals of the Draft WPHIP, which will replace the 1995 Vegetation Management Plan, are:

  • To protect Marin’s communities, water supply and natural resources from catastrophic wildfire;
  • To preserve habitats, plants and animals into the future;
  • To prepare for and adapt to future changes.

The next step in the environmental review process is the scoping period, during which MMWD will accept comments on what should be included in the environmental review. The 30-day scoping period begins today, November 1, with a scoping meeting at San Rafael City Council Chambers set for Thursday, November 15, 7:00-9:30 p.m. The scoping period ends December 3.

The environmental review process will lead to the release in 2013 of a draft environmental impact report (EIR), which will include an assessment of the potential impacts of implementing various alternative approaches or of continuing the current program without changes. The draft EIR will also recommend the alternative approach that best protects the water supply, Mt. Tamalpais and the communities in MMWD’s service area.

More information on the draft WPHIP is available on MMWD’s website.
