With the start of a new rainfall year on July 1, 2011, we are now back to zero inches of rain for the year to date. We typically don’t receive any measurable rainfall until October, and sometimes not until November, but rainfall this calendar year has been far from typical, so we’ll have to wait and see what fall 2011 has in store for us.
As of July 24, reservoir levels were 93 percent of capacity, or 73,683 acre-feet (one acre-foot is 325,851 gallons). These levels are much higher than the average for that date of 78 percent, or 61,709 acre-feet.
Water use has been on the low side this summer. Last week’s consumption averaged 30.5 million gallons, which translates into a per capita figure of 160.6 gallons. Per capita consumption for the same week in 2010 was 173.1 gallons.
For the month of June we released 171 million gallons, or a total of 525 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.
