WEAVERVILLE, Calif. - The Bureau of Reclamation announced today that Lewiston Dam releases into the Trinity River will increase Tuesday, April 17, and will reach approximately 1,900 cubic feet per second (cfs) by Sunday, May 13, and remain at peak flow for one day. Four sub-peaks are scheduled at discharges of 1,390 cfs on Wednesday, April 18; 1,400 cfs on Sunday, April 29; 1,600 cfs on Saturday, May 5; and, 1,620 cfs on Friday, May 25.
People residing near the river or recreating on the river can expect river levels to increase and should take appropriate safety precautions. Landowners are advised to clear personal items from the floodplain prior to the releases.
The releases will start ramping down May 26 until the summer base flow of 450 cfs is reached June 30. The releases for this “critically dry" 2018 water year will result in an annual total volume of 369,000 acre-feet.
