Central Nebraska Public Power and Irrigation District will lower Jeffrey Lake near Brady on Monday as part of a maintenance project on the Jeffrey Hydroplant generation units.
The lake level will fluctuate up and down the next two weeks, before returning to normal winter operating levels by Feb. 1.
During that time, it will be unsafe to use the lake for any recreational activities or shoreline maintenance because of the constantly changing water levels.
Water levels in other CNPPID system lakes won’t be affected by the fluctuations at Jeffrey Lake.
