Central Coast residents warned to evacuate as lake nears capacity: ‘Stay out of the water’
Water releases from Lake Cachuma are expected to begin Saturday morning, ahead of upcoming storms, according to Santa Barbara County officials.
Lake Cachuma was at 86.4% of capacity as of 10 a.m. Friday, and about 9 feet below its spill level, according to the Santa Barbara County Public Works Department.
The U.S. Bureau of Reclamation, which operates the reservoir, has indicated it plans to release water at the rate of 2,000 cubic feet per second into the Santa Ynez River below Bradbury Dam, Matt Young, manager of the Santa Barbara County Water Agency, told Noozhawk.
That should boost the flow of the river to an estimated 4,000 cubic feet per second.
“Flooding issues are not expected at that level,” Young said.
At its peak during last week’s storms, the river was flowing at about 20,000 cubic feet per second through Lompoc, Young said.
The releases are based on modeling conducted by the Bureau of Reclamation, and are intended to make room for new inflow to the Cachuma reservoir expected from storms over the weekend.
Although those weather systems are not expected to be as intense as the one that hammered the county last week, the rain will be falling on already-saturated soils, which will increase the potential runoff.
The plan, Young said, is to release smaller amounts of water from Lake Cachuma over a longer period of time, as opposed to letting the lake fill and then spill with less control.
The lake still is expected to completely fill eventually, he said.
Evacuation warning for Santa Ynez, Santa Maria rivers
The Santa Barbara County Sheriff’s Office will be flying a helicopter over the Santa Ynez River in the Lompoc area on Friday and Saturday to give evacuation warnings to people living in the riverbed, according to Sgt. Sergio Arias of the Lompoc Police Department.
The riverbed in the Lompoc area has become a site for encampments used by homeless people.
“Water rescues are extremely hazardous,” Arias said in a press release. “Please do not put public safety officers at risk. The Lompoc Police Department requests that public stay out of the riverbed.”
The helicopter will be making the following announcement, according to Raquel Zick, sheriff’s spokeswoman: “Cachuma Lake will be releasing water and rain is expected for the next few days.The water levels are expected to rise. It is unsafe to be in the riverbed area. Stay out of the river. Temporary shelter is available.”
Similar warnings will be provided by the helicopter over the Santa Maria River, Zick said.
