226.53 m NN
226.53 m NN is the gauge reading converted with SYKE's official datum correction. It is elevation, not a share of stored water. The percentage is where that elevation sits between the lower and upper levels in the regulation permit, both shown on NN. A lake can stand above 100% when it is over the upper limit. SYKE does not publish the stage-storage curve that would turn this into a volume percent. Compared with 2025-10-04, the level is 0.66 m higher.
