The rain that fell last week on the Mt. Tamalpais Watershed measured 0.21 inches, bringing total rainfall to date (July 1-September 21) to 0.25 inches. While the small amount of rain was enough to be measured and to help settle the dust, it did not contribute to higher reservoir levels.
Here are the current water statistics:
Reservoir Levels: As of September 21, reservoir storage is 51,662 acre-feet,* or 65% of capacity. The average for this date is 55,148 acre-feet, or 69% of capacity. Total capacity is 79,566 acre-feet.
Rainfall: Rainfall this year to date (July 1-September 21) is 0.25 inches. Average for the same period is 0.52 inches.
Water Use: Water use for the week of September 15-21 averaged 25.19 million gallons per day, compared to 30.06 million gallons per day for the same week last year.
