Lake Zumbro Spring and Summer Pool

Monday, March 23rd, 2015

The level of Lake Zumbro will be raised from winter pool (913.0 MSL) to the normal summer pool (914.5 MSL) beginning March 23, 2015.  It will take approximately one week for the gradual transition to summer pool to be completed.  Lake Zumbro will be maintained at normal summer pool (914.5 MSL) throughout the rest of the spring and summer season, to the extent possible.  However, the public should be aware that the Zumbro Hydroelectric Plant has extremely limited capacity to pass flood flow, resulting in occasional high water events that exceed normal pool.

Real-time lake level information is available on the RPU web site ( For additional information regarding the Zumbro Dam and Hydroelectric Facility please contact Tony Benson 280-1534 or Todd Osweiler, 280-1589.

Tips for safe boating:

Watch the weather. Be aware of changing water levels and conditions that would expose logs, snags or cause floating debris. Be cautious when boating in the vicinity of the dam. Do not proceed past the warning signs and buoys. Tell someone where you are going, who is with you, and how long you will be away. Avoid standing, and when changing seats, stay low and near the centerline of your boat. Be ready for trouble when a powerboat passes you in a narrow channel. Maintain a safe operating speed. Always wear approved personal flotation devices (PFD).
