No change this month in the patterns for reservoir levels, which continue to be above average, and water use, which continues to be below.
Here are the most current figures:
Reservoir Levels: As of September 25 the reservoirs contain 65,641 acre-feet,* or 81 percent of capacity. This volume is well above the average for this date of 53,350 acre-feet, or 67 percent of capacity.
Water Use: Per capita water use for the past week was 156.8 gallons per day; for the same week in 2010 it was 158.4 gallons.
Creek Releases: For the month of August we released 197 million gallons, or a total of 603 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.
Rainfall: We received our first measurable rainfall for the year on Sunday, September 25, in the amount of 0.03 inches. (Our rainfall year is July 1 – June 30; rainfall is measured at Lake Lagunitas.) Average rainfall through that date is 0.62 inches.
