October Storm Dropped 7.72 Inches of Rain in Lake Lagunitas Local Public Issues, posted by Editor, Pacific Sun Online, a resident of the San Rafael neighborhood, on Oct 28, 2009 at 11:03 am
The October 13th storm produced rainfall measuring 7.72 inches at Lake Lagunitas, and was the biggest October storm since 1962, according to MMWD's Inside Source newsletter. It goes on to report that "rainfall at Lake Lagunitas for the month of October so far is 9.63 inches, well above the monthly average of 1.83 inches. Even with no additional rain this month, October 2009 will be the sixth wettest October in the 131 years that rainfall records have been kept at Lake Lagunitas. The average annual rainfall at Lake Lagunitas is about 52 inches.
"Significantly above-average rainfall (more than twice the average) has occurred in October about 20 times during those 131 years. Interestingly, about 60 percent of those years ended with above-average annual rainfall, about 20 percent turned out to be average, and the remaining 20 percent were below average.
"As these statistics indicate, the heavy rains this month are a promising start for the year. However, early rains have also occurred in drought years. October 1975 was also very rainy (about 8 inches), yet the 1975-76 rainy season turned out to be very dry and ended up as the first year of the most severe drought of record for MMWD."

Thank you very much for the good news. Lets all hope that this will be a good year for rainfall in all if the 6 water districts that serve Marin. Hopefully the public will be able to vote on the MMWD's proposed desalination plant AFTER the results of the 2010 census are published. If we continue to see a decline in population as we have seen from 2000 to 2007, and if we receive above average rainfall, we can squelch the desalination plant project for good.

Not so fast. You know we will fall back into normal rainfall patterns so lets do put in the desalinization plant at Stinson for future needs and to keep the water district bills lower than they are going to raise come hell or high water. The first year we get below average rainfall, we will get a raise so lets do everything possible to keep the raises reasonable.

johnnymarin, you need to do some research.
If we needed a desalination plant (and we do not), it would be much better to put it out on the open ocean than the proposed location in the shallow part of the San Pablo bay next to the CMSA sewer plant. BUT it would be cost prohibitive. To build a pipeline from the coast and the extra electricity to pump water up the mountain to the MMWD service area would be astronomical, and your water rates would skyrocket.
