*Notice: Anticipated flows are always preliminary and are provided for informational purposes only. Flows are subject to real-time changes in weather and runoff conditions, and operations related to hydroelectric generation, flood control, and Federal Energy Regulatory Commission license requirements. This data is not intended to be used for flood forecasting. Storm runoff can produce extremely cold and variable flow releases below Englebright Reservoir. Flows can range from the minimum flow requirement to thousands or 10s of thousands cubic feet per second and change rapidly. Be prepared for sudden flow changes when recreating on the lower Yuba River or avoid the river altogether for your safety. Additional information can be viewed online.
Releases from Englebright Reservoir at the Smartsville gage are currently at 1,000 cfs. With the current forecast, we are going to hold the 1,000 cfs in expectation that storm flows will fill Englebright. Projections are for Narrows 1 and Narrows 2 to start increasing flows early on Thursday, Jan. 17, up to full capacity. Englebright is expected to start spilling on Thursday, Jan. 17. When storm flows subside and Englebright Reservoir's elevation drops to 523 feet, flows through Narrows 1 and Narrows 2 will be reduced at a rate of 100 cfs per hour, down to 1,100 cfs. Peak flows during this storm event are projected to exceed 6,500 cfs. All of the above information is based on the Jan. 14 forecast and is subject to change as needed to manage flows in the Yuba River and to comply with license and flow requirements. Flows can change swiftly and suddenly, so be prepared when recreating on the lower Yuba River or avoid the river for your safety.
New Bullards Bar Reservoir is operated to preserve the flood pool, therefore storm and flood control operations may require higher or lower releases. The minimum release from Englebright Reservoir at the Smartsville gage is 1000 cfs. On Jan. 16, the minimum flow requirement drops to 700 cfs. Currently, the minimum flow requirement at the Smartsville gage, through February is 700 cfs. Due to the storm event this week, it is expected that higher releases will be passed through and over the Englebright Dam, with peak flows exceeding 6,500 cfs. Flows can change swiftly and suddenly, so be prepared when recreating on the lower Yuba River or avoid the river for your safety.
*Reservoir elevations, storage and flood space data are based on midnight values, and flows are averages from the previous day.
