Rainfall, debris buildup contribute to Upper Lake flooding
LAKE COUNTY, Calif. — Following the weekend’s heavy rain, flooding was reported by residents of Upper Lake on Monday.
The area around First and Washington streets in Upper Lake was taped off on Monday due to water going over the road.
That location also experienced flooding in 2023.
Flooding also was reported in Scotts Valley on Monday.
In response to questions from Lake County News, Public Works Director Scott De Leon confirmed that the area along Washington Street in Upper Lake experienced flooding from the overnight rainfall, with the worst area being between First and Second streets on the west side of Clover Creek. He said the area on Washington Street south of First Street also had some minor flooding.
De Leon said debris in the original channel of Clover Creek between First and Second streets is contributing to the situation.
“There is a large wood jam consisting of several large trees, limbs and berries, and from what we can see, it appears the flows hit that debris jam and got pushed over the private levees,” he said.
Lake County News received reports that one of the levee's diversion gates has been broken for months and couldn’t be closed to stop the flow.
De Leon acknowledged that one of the gates is damaged, but he said, “the damage prevents the gate from completely opening – not closing – and that gate is closed. The diversion structure actually has 5 culverts, two with gates and the other three have steel plates covering them to reduce flows. Based on our inspection today, the Clover Creek channel downstream of the diversion structure carried the flows, and it was the debris jam that created the problem.”
He said his county road department staff worked with the Northshore Fire Department to place pumps to help drain the area, “which according to staff was effective.”
By the end of the day Monday there was approximately 6 inches of water on Washington near First Street, with the rest of the street clear, De Leon said.
“Water Resources staff will be evaluating the wood jam to see if any of the outside contractors currently in the county performing vegetation management can tackle it,” he said. “This is all private property, so county crews can’t perform the work, but we are trying to utilize whatever resources we have available to help the situation.”
