CALISTOGA -- The Santa Clara Valley Water District will purchase a portion of Calistoga’s allotment from the State Water Project, generating nearly $80,000 for the city’s enterprise fund.
Calistoga will sell 400 acre-feet of water to the Santa Clara Valley Water District for $200 per acre-foot (one acre-foot is about 326,000 gallons). The district will “return” 50 percent of that water exchange within the next 10 years.
The water being sold is not water that actually comes through the city, nor is it water that the city could or would use, officials said. It is a portion of Calistoga's state water allocation, which this year is 770 acre-feet. To date, Calistoga has used 20 acre-feet of the 2018 allocation, said Public Works Director Mike Kirn.
The city's main supply is the local, city-owned Kimball Reservoir.
The city is allowed to “carry over” a portion of its water allocation from year-to-year, but what isn’t used is essentially “lost,” he said.
Calistoga has sold water in the past, such as in 2013 when it sold 1,100 acre-feet, and again in 2016 when it sold 500 acre-feet of water.
After reviewing the current demand and usage, Kirn estimates that the city will use about 300 acre-feet of its 2018 state allocation.
