Due to the fire activity, Trinity Dam became isolated from the power network and continues to serve a local area of power for safety purposes. Spring Creek and Carr power plants are currently down. As a result, Lewiston water elevations were managed by emergency increased releases from Lewiston Dam and Carr Bypass.   Over Friday night, Lewiston Lake reservoir rose higher than the normal operating range which resulted in an increase in release from the Trinity River to about 1,100 cfs.  River releases are coming down today but are still higher than what was noted yesterday.  Please take extra precautions due to varying releases on the Trinity River.   We are trying to reduce the lake levels but expect this will be difficult due to the facility communication issues and power generation situation.   Low lying areas surrounding the lake and marinas at Lewiston Lake are expected to be affected by the higher and variable lake levels.     Reclamation managed to get Lewiston Dam releases to the Trinity River down to about 750 cfs by 3:00 pm Saturday afternoon and will remain at this level until further notice.

Please cancel the previous order:

Releases will remain at approximately 750 cfs from Lewiston Dam.

Release increases are due to mandatory evacuation of Trinity power plant.
