In the last seven days Kimball Reservoir received about 2-1/2 inches of rain with the heaviest rainfall on Monday at a little more than 1-1/2 inches, officials said.
“Yesterday’s inflow into the reservoir was approximately 220,000 gallons – which was approximately the same amount that we produced through the treatment plant. So far the water turbidity looks pretty good,” said Mike Kirn, public works director. “
Areas around Kimball were burned by the October fires and after the fires were extinguished the city worked with Cal Fire in taking erosion control measures that seem to be effective.
“During November and December we saw a pretty decent grow back of the grass in the watershed which has helped minimize erosion impacts,” Kirn said.
More than four inches of rain fell on some higher elevations in Napa County before Monday’s storm wound down Tuesday morning.
A gauge at the city of Napa’s Corporation Yard on Jackson Street recorded 2.79 inches, and Atlas Peak received 2.92 inches.
Gauges recorded 3.74 inches on Mount Veeder, 4.56 inches in Angwin and 3.35 inches on Sulphur Creek in St. Helena.
The National Weather Service had issued a flash flood watch, but no incidents were reported locally.
This week’s storm provided the season’s highest rainfall totals after a nearly bone-dry December.
