October began without any rain and apparently the month will end that way, too. Let’s hope November brings rainy weather. While our reservoir levels are almost normal for this time of year, at 62 percent of capacity there is plenty of space to capture water. (See current photos of the reservoirs on our Facebook page)
In response to the record-dry spring of 2013 and to preserve our reservoir levels to the degree possible, we made the following changes to our normal water operations this year:
- We carefully balanced the use of imported Russian River water with our reservoir water supply, importing more Russian River water than is typical in the summer months;
- We used more water from Nicasio Reservoir in West Marin, allowing us to save more water in our reservoirs on Mt. Tamalpais;
- We turned on our recycled water plant earlier in the spring than usual to reduce demand on our potable water supply.
Here are the current water statistics:
Reservoir Levels: As of October 27, reservoir storage is 50,366 acre-feet,* or 63 percent of capacity. The average for this date is 51,728 acre-feet, or 65 percent of capacity. Total capacity is 79,566 acre-feet.
Rainfall: Rainfall this fiscal year to date (July 1-October 27) is 1.16 inches. Average for the same period is 3.12 inches.
Water Use: Water use for the week ending October 27 averaged 26.5 million gallons per day, compared to 20.5 million gallons per day for the same week last year.
Supply Source: Last week we averaged 21.1 million gallons per day from our reservoirs and 5.4 million gallons per day from the Russian River.
Creek Releases: During the month of September 2013 MMWD released 266 million gallons, or a total of 817 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.
