  • Lake Celilo water levels to fluctuate through Dec.

    During October, November and December, the water levels of Lake Umatilla, located between The Dalles and John Day dams, will likely fluctuate between elevation 262.0 and 266.5 feet. The lake could reach as low as 257 feet or as high as 268 feet to help contain water if the region experiences a large (unlikely but possible) winter flood.
