Numerous roads and bridges remained closed throughout San Luis Obispo County. See the county’s updated map here for details.

Chimney Rock

There are people who chose to stay in their homes near Lake Nacimiento and are unable to leave their neighborhood due to the road closure at Chimney Rock Road outside Paso Robles, according to the County of San Luis Obispo Public Works Department. The eroding ground surrounding the culvert below the road surface has made the road unsafe. However, public works crews and contractors have been working 24 hours a day and have managed to temporarily rebuild the road. Inspectors are making sure the temporary repair is safe for limited vehicle traffic.

In addition to the Chimney Rock closure, there are many other roads that are closed due to unsafe conditions. You can find the list and map at readyslo.org at this link: Road Closures – San Luis Obispo County (emergencyslo.org). Citizens are reminded not to travel past road-closed signs. A road can appear safe on the surface and be degrading underneath the asphalt. There are a few closures that have left residents isolated. In the case of medical need, the county can conduct an emergency transport to a health-care facility.

Water releases from Nacimiento Reservoir increase slowly for public safety

Extremely small water releases from Nacimiento Reservoir into the Salinas River that have been on-going through the series of current winter storms are required for safe operations. The current releases increased slowly from Friday overnight to Saturday to reduce the risk of the reservoir spilling over as a result of the next series of storms in our area.

During the recent storms, reservoir levels dramatically increased from 27% to 76% since Dec. 31, 2022. Approximately 183,000 acre-feet of water were captured and not released into the river, significantly reducing flood impacts throughout the Salinas Valley. However, at this point, minimal flood control releases must commence, according to the County of Monterey. “It is healthy for the system to release small amounts of water now, versus waiting and having to release larger amounts of water later,” said District 3 Supervisor Chris Lopez.

“It is not safe to keep the flood pool (the term used to describe the upper capacity of the reservoir) full,” said County of Monterey County Administrative Officer Sonia M. De La Rosa. “With the recent weather, now is the best time to begin this normal operational procedure.” During the current storm events, the fractional releases from the reservoir were 60 cubic feet per second, compared to the flood-stage flow of the river which was well over 40,000 cubic feet per second. The small reservoir releases will increase to 350 cubic feet per second, and then slowly increase to under 4,000 cubic feet per second for about a week.

County experts are timing the releases to complement the lower river levels at the south end of the valley. And, because it takes three to five days for water to travel from the Nacimiento Reservoir to Spreckels, the current river flood levels at that location will have passed. “The releases that are being initiated will follow the lower flows in the river. Our conservation pool will be full through this weather event and will be available for releases during the dry months. Such measures are highly beneficial for groundwater recharge and diversions to the Castroville Seawater Intrusion Project,” said Certified Floodplain Manager & Operations Manager for the Monterey County Water Resources Agency Shaunna Murray.
