The level of Lake Zumbro will be lowered from normal summer pool (Elevation 919.7 dam datum) to the winter pool beginning on October 31, 2005. The drawdown to winter pool will be accomplished by November 10. During the months of December through March, Rochester Public Utilities (RPU) will attempt to maintain the lake level within the winter pool range of 918.0 – 918.5, which is about 1.5 to 2 feet below the crest of the dam. The public should be aware that heavy precipitation and runoff events during this time-frame could result in high water levels.

Tips for lake ice safety:

Be extremely careful during winter activities that involve Lake Zumbro, such as ice fishing, snowmobiling or just walking out on the frozen lake. Watch the weather and river flow. Ice thickness and condition can vary greatly. Look out for ice heaves and exposed logs and snags. Be cautious in the vicinity of the dam. Deicing equipment has been installed along the upstream face of the dam resulting in open water and/or thin ice. Do not proceed past the warning signs and buoys.
